Software Testing Advice for Novice Testers

Novice testers have many questions about software testing and the actual work that they are going to perform.  As novice testers, you should be aware of certain facts in the software testing profession.

The tips below will certainly help to advance you in your software-testing career.  These ‘testing truths’ are applicable to and helpful for experienced testing professionals as well.  Apply each and every testing truth mentioned below in your career and you will never regret what you do.

Know Your Application
Don’t start testing without understanding the requirements.  If you test without knowledge of the requirements, you will not be able to determine if a program is functioning as designed and you will not be able to tell if required functionality is missing.  Clear knowledge of requirements, before starting testing, is a must for any tester.

Know Your Domain
As I have said many times, you should acquire a thorough knowledge of the domain on which you are working.  Knowing the domain will help you suggest good bug solutions.  Your test manager will appreciate your suggestions if you have valid points to make.  Don’t stop by only logging the bug.  Provide solutions as well.  Good domain knowledge will also help you to design better test cases with maximum test coverage.  For more guidance on acquiring domain knowledge, read this post.

No Assumptions In Testing
Don’t start testing with the assumption that there will be no errors.  As a tester, you should always be looking for errors.

Learn New Technologies
No doubt, old testing techniques still play a vital role in day-to-day testing, but try to introduce new testing procedures that work for you.  Don’t rely on book knowledge.  Be practical. Your new testing ideas may work amazingly for you.

You Can’t Guarantee a Bug-Free Application
No matter how much testing you perform, you can’t guarantee a 100% bug-free application.  There are some constraints that may force your team to advance a product to the next level, knowing some common or low priority issues remain. Try to explore as many bugs as you can, but prioritize your efforts on basic and crucial functions.  Put your best efforts doing good work.


Think Like An End User
This is my top piece of advice.  Don’t think only of a technical guy.  Think like customers or end users.  Also, always think beyond your end users.  Test your application as an end user.  Think how an end user will be using your application.  Technical plus end user thinking will assure that your application is user-friendly and will pass acceptance tests easily.  This was the first advice to me from my test manager when I was a novice tester.

100% Test Coverage Is Not Possible
Don’t obsess about 100% test coverage.  There are millions of inputs and test combinations that are simply impossible to cover.  Use techniques like boundary value analysis and equivalence partitioning testing to limit your test cases to manageable sizes.

Build Good Relations With Developers
As a tester, you communicate with many other team members, especially developers. There are many situations where tester and developer may not agree on certain points.  It will take your skill to handle such situations without harming a good relationship with the developer.  If you are wrong, admit it.  If you are right, be diplomatic.  Don’t take it personally.  After all, it is a profession, and you both want a good product.

Learn From Mistakes
As a novice, you will make mistakes.  If you don’t make mistakes, you are not testing hard enough!  You will learn things as you get experience.  Use these mistakes as your learning experience.  Try not to repeat the same mistakes.  It hurts when the client files any bug in an application tested by you.  It is definitely an embracing situation for you and cannot be avoided.  However, don’t beat yourself up.  Find the root cause of the failure. Try to find out why you didn’t find that bug, and avoid the same mistake in the future.  If required, change some testing procedures you are following.

Don’t Underestimate Yourself if Some of Your bugs Are Not Fixed
Some testers have assumptions that all bugs logged by them should get fixed.  It is a good point to a certain level but you must be flexible according to the situation.  All bugs may or may not be fixed.  Management can defer bugs to fix later as some bugs have low priority, low severity or no time to fix.  Over time you will also learn which bugs can be deferred until the next release.  Read an article on ‘How to get all your bugs resolved‘.

Over To You:
If you are an experienced tester, what advice do you like to give to novice testers?

hi vijay,

Excellent Article

Excellent Article.
Many experience for for Novice Testers

This artical is very helpful for those who are new in testing profession.

#6 kailash

All the things that you mention is true, take both condition valid and invalid.while testing think to break the application so are good to find out the bugs.

A test engineer should have a high level of thinking, what the application suppose to do or what he is not suppose to do.

Thanks for your support.

I have a point for the Novice testers …Your mantra should be “Quality ” this should be ur attitude towards u r work .No matter what domain and what extend be Diplomatic and try admit ur self in the user’s place then u will know what are errors can occur …u cant measure everything happens as it is,u should …..1.What is the objective of the project 2.What are u going to test 3..How are u going to test..4.What is the outcome of the testing …5.u should be thinking in positive way as well as Negative way ,if u think like this then u can shine in ur life as a Quality person …

#9 Kavita

Good work

#10 Bose

This article is not only good for starters, it’s also well applicable to the experienced testers. I really enjoyed it. My contribution is that , as a tester aiming at finding defects in order to improve the quality of the product, You have to be open minded and positive. Be inquisitive enough and always ask yrself various questions about how best the software can be while not deviating from the requirements…cheers!

#11 Inder P Singh

Tip 1. Use all existing resources e.g. requirements documentation, design documents, help files, closed and currently open bugs, discussions with other testers/ developers to build your knowledge of the application under test.

Tip 2. Instead of focussing on finding severe bugs only, focus on the number of bugs. Many efficient test methods could provide you a good number of bugs for the time you put in testing. Out of all the bugs that you find, there will undoubtedly be some gems and your team would be thankful to you for finding those bugs.

Tip 3. Think about the causes of bugs that you find or others find. If possible, get some of this knowledge from the developers. Once you have an understanding of the common causes of bugs, you would be able to focus more on the problem areas of the application.

#12 Inder P Singh

Tip 4. If another tester finds a good bug, congratulate that person and if possible, get that person to share the method or the though process he/ she used that resulted in the discovery of the bug. This way, you could build up your own set of test methods.

Tip 5. Remember, it takes time to develop expertise in any profession. Be patient when faced with problems or when frustrated.

Wish you good testing experience!

#13 yas

My advice for new testers not to ignore a single bug no matter how big or small, because later if other team member discover it you’ll regret that you didn’t log it.
even it was an extra space you should give it enough care
thanks,

#14 Dalip Kumar

Thanks Mr. Vijay for all your extreme knowledge about testing. It gives me way to do much better in testing efforts. I am very new in this field. I am non science graduate. You pls send me all your valuable views at my mail id i.e. dalipkumar_nic@yahoo.co.in

#16 hirani

nice article

#17 Vijay

Good advice from readers too!

Some excellent tips from Inder P Singh . But Inder I am disagree with you on your point no.2

“Tip 2. Instead of focussing on finding severe bugs only, focus on the number of bugs.”

If I am testing an application I will try to find and log all possible bugs in application. May be small or severe bugs.
The count doesn’t matter for me. What I will focus on is test coverage and a bug free application.

#18 kishore

Hello
Nicely compiled
My advice is to foucs on positive scenario first and then approach towards negative test cases.
Chances are there you may miss out some positive scenario in the race of finding bugs following negative approach.

#19 yald

My advice to testers: define a list of test ideas and test des you will be sure you have not missed any requirement aneply for each point of the list. Doing thid case.
You may have test cases and scenarios defined by your test analyst but there is no guarantee that they completely cover all cases system can work/break.

And think about automating some of you tests…

#20 yald

I’m sorry… my previous post should look like this:

” My advice to testers: define a list of test ideas and test and test deeply for each point of the list. Doing thies you will be sure you have not missed any requirement and case.
You may have test cases and scenarios defined by your test analyst but there is no guarantee that they completely cover all cases system can work/break.

#21 Inder P Singh

@Vijay,

Thanks for the nudge! My Tip 2 definitely needs clarification and additional information. It should not be taken verbatim. The final intent of this tip is to develop quality bugs. Let me explain how.

1. The tester may choose to log every bug the moment it is discovered. I would not prefer to do so. Instead, I would hold the bugs for some time and analyze them. This analysis might result in finding that a) Multiple problems are not separate bugs but manifestations of a single bug e.g. a single bug found in multiple test environments. b) A problem is not a bug by itself but simply the symptom of a bigger bug. I would prefer to log the bugs only after proper analysis.

2. While testing and after discovering some bugs, it is possible for the tester to become a little complacent. In my opinion, the tester should stay dissatisfied with the bugs found thus far. This invokes the thought process about the tests not yet conducted, any regression bugs that might be open etc.

If the tester continues to think and put in effort to discover more and more problems and analyze all the discovered problems properly, the tester should end up with good quality bugs. The tester should not focus on bug count, per se but on discovering more and more problems.

#22 yogini

Good discussion between the expert bolgers and Mr. Vijay. Very informative for freshers.

As I am a software test engineer, the points discussed above are quite close to software testing in real environment.

What my suggestions for the novice tester:

1) Always try to be a good listener as tester should devlop the habit of listening from the initial stage to understaned the projects more deeply.

2) Don’t be in hurry to log the bugs, unless you understand the whole procedure.

3) Always develop a good relationship with the developers, as we are appointed to point out mistakes from what they have developed, sometimes there may be clashes between a developer and tester regarding the work ( as developer gets frustated on seeing the long list of bugs. To develop the code is easy than fixing the bug which is somewhat difficult for them).

4) If you are working in a team as a novice tester try to discuss between yourselves as how to improve testing skills , you will get to learn many things from the experienced testers.

5) Don’t try to hide your mistakes, accept it gracefully it will help you to develop your testing skills in future .

Be good tester, and have patience.

Good job

#25 ksrinivas

hi, i am new to software testing. could u please tell me the good institute for testing.

#26 asritha

hi am novice to testing.am a fresher and no project experiance till now.am going to start my first project next month.i want some tips to get success in that project.I have to prepare test plan also.The requirement document is of 70 pages,so tell me the areas of requirement doc where i have to concentrate to write a test plan.

#27 Vijay

@Inder P Singh
Right, Bug count should not be the final aim and major of tester’s performance.

@yogini
Point no. 2 is good.
“Don’t be in hurry to log the bugs, unless you understand the whole procedure.”

If you log all the bugs along the way you will end up getting most of them marked as invalid. Troubleshoot and go to root cause to know whether the bug symptom is a bug or just a beginning of another major problem. Don’t forget to note down all steps to reproduce bug symptoms, finally this will help you write good bug report.

@asritha
Read the requirement doc carefully and understand the business logic. This will help you to visualize complete picture of final product. You will get clear idea of testing time required for each module, resource allocation, test schedule, risks associated and major modules to be tested. What remain will be just fitting your requirements in standard test plan.

For sample test plan and test plan guidance see posts on:
http://www.softwaretestinghelp.com/category/test-plan-template/

#28 William Echlin

Some really good points in this list. I think the point about “100% Test Coverage Is Not Possible” is a very important one. I would extend this to say that it is important to set realistic, clear, and achievable goals for both the team and yourself. 100% coverage isn’t possible but setting your goals (perhaps coverage related) helps to keep the team motivated even if they know they can’t test everything.

The other point I think is very important is that I believe it is helpful to also look for positives in the software. What I mean by this is that quite often in software testing we are about being critical and pointing out mistakes. It can help lift both the test teams and the development teams moral if the testers point out good things about the software here and there as well as the bad things. Give credit where it is due.

#29 Vishal

Hi Vijay,

Recently I had been to an interview and encounted to a new term hard error and soft error.

They have asked me the difference between Hard and soft error.

If u have the ans. pls reply for the thread.

ACCEPTANCE TESTING. Testing to verify a product meets customer specified requirements. A customer usually does this type of testing on a product that is developed externally.

BLACK BOX TESTING. Testing without knowledge of the internal workings of the item being tested. Tests are usually functional.

COMPATIBILITY TESTING. Testing to ensure compatibility of an application or Web site with different browsers, OSs, and hardware platforms. Compatibility testing can be performed manually or can be driven by an automated functional or regression test suite.

CONFORMANCE TESTING. Verifying implementation conformance to industry standards. Producing tests for the behavior of an implementation to be sure it provides the portability, interoperability, and/or compatibility a standard defines.

FUNCTIONAL TESTING. Validating an application or Web site conforms to its specifications and correctly performs all its required functions. This entails a series of tests which perform a feature by feature validation of behavior, using a wide range of normal and erroneous input data. This can involve testing of the product’s user interface, APIs, database management, security, installation, networking, etcF testing can be performed on an automated or manual basis using black box or white box methodologies.

INTEGRATION TESTING. Testing in which modules are combined and tested as a group. Modules are typically code modules, individual applications, client and server applications on a network, etc. Integration Testing follows unit testing and precedes system testing.

LOAD TESTING. Load testing is a generic term covering Performance Testing and Stress Testing.

PERFORMANCE TESTING. Performance testing can be applied to understand your application or WWW site’s scalability, or to benchmark the performance in an environment of third party products such as servers and middleware for potential purchase. This sort of testing is particularly useful to identify performance bottlenecks in high use applications. Performance testing generally involves an automated test suite as this allows easy simulation of a variety of normal, peak, and exceptional load conditions.

REGRESSION TESTING. Similar in scope to a functional test, a regression test allows a consistent, repeatable validation of each new release of a product or Web site. Such testing ensures reported product defects have been corrected for each new release and that no new quality problems were introduced in the maintenance process. Though regression testing can be performed manually an automated test suite is often used to reduce the time and resources needed to perform the required testing.

SMOKE TESTING. A quick-and-dirty test that the major functions of a piece of software work without bothering with finer details. Originated in the hardware testing practice of turning on a new piece of hardware for the first time and considering it a success if it does not catch on fire.

STRESS TESTING. Testing conducted to evaluate a system or component at or beyond the limits of its specified requirements to determine the load under which it fails and how. A graceful degradation under load leading to non-catastrophic failure is the desired result. Often Stress Testing is performed using the same process as Performance Testing but employing a very high level of simulated load.

SYSTEM TESTING. Testing conducted on a complete, integrated system to evaluate the system’s compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic.

UNIT TESTING. Functional and reliability testing in an Engineering environment. Producing tests for the behavior of components of a product to ensure their correct behavior prior to system integration.

WHITE BOX TESTING. Testing based on an analysis of internal workings and structure of a piece of software. Includes techniques such as Branch Testing and Path Testing. Also known as Structural Testing and Glass Box Testing.

Hi All
I am working on a project in which we are using liferay and alfresco as a database. Applicaton demands that there will be a sign in functionality and that users also saves in mailing list (Lyris using as a mailing list). so whem any user sign in liferay than his name should save in liferay database and at the same time in the mailing list as well in another database so what can be the possible scenarios for Rollback Testing.
Kindly help as I have to test that both the database gets updated as a person sign in…………………..

In short what can be the possible scenarios of rollback……….be a most destructive user (think all possible destructive possibilties)

Good post.

Freshers should also know that testing tools means not only the tools used for Test Execution, but also for Test Design and Test Data.

Please explore the free Online edition of http://www.TestersDesk.com and add it to your resumes as “Test Design and Data Generation Tools: http://www.TestersDesk.com“.

What is dat base testing

Data bas testing basically include the following.
1)Data validity testing.
2)Data Integritity testing
3)Performance related to data base.
4)Testing of Procedure,triggers and functions.

for doing data validity testing you should be good in SQL queries
For data integrity testing you should know about referintial integrity and different constraint.
For performance related things you should have idea about the table structure and design.
for testing Procedure triggers and functions you should be able to understand the same.

#39 CH.girish chander raju

hi my dear testing freshers,

iam suggesting you five steps to become reputed professionals:
1)Be a certified testing professional from ISTQB or TESTING SCENSE etc.because it brings you respect aznd recognisation too in the organisation
2)when you are in work environment,be a negative attitude tester.
3)Be patient and passionate
4)maintain Good relation with all your team(i mean developers,testers,administrators).
5)Always treat you as END USER and test the application.

Thank you

Please guide for the further proceedings friends.

hello there.. this is a great thread! i’ve been around the block doing some QA, some dev, and some PMing..

one thing i think is important to add (although it’s kinda been covered in the thread above), really know the specs of the app that you’re testing, and then pretend you’re a dumb enduser that knows nothing about the internet when testing begins. that’s usually the best way to get started, and when you’re done pretending you’re dumb you’ll find that you understand the app much better and can move onto more advanced tests.

if you’ve gone through all the PM’s documentation, you can think of that “pretending i’m dumb” phase as a “get to know the app” phase, ’cause really you won’t understand everything from just reading functional specs or statements of work.

also, for novices and pros, it’s probably a good idea to learn a little bit about usability and just be more aware/critical when you’re surfing around on your own time. what i mean by this is, just say you’re surfing bestbuy’s site.. take note of how their features work, take note of how easy or not easy it is to use their site, take note of how the scoping of the site works too.. like how the left bar is a child of the top nav elements. internet trends are important too for usability.. for example.. 10 years ago left bar and frames were the rage.. nowadays nobody uses the left bar for primary nav as most websites have top navs with left bars as a secondary nav, and.. well, what’s a frame? haha

you’ll be surprised how developers sometimes just get the job done without thinking about the implementation and how it can be confusing to an end user. there’s nothing wrong with this, since sometimes a developer will be too close to the project and doesn’t have the luxury of stepping back. it’s your job to help them regain their focus all in the name of quality.

#44 Laurie

A fantastic list.

I would add: Think outside the box when it comes to the definition of “bug”.

I remember my first QA project, I was the only tester to read the ‘help page’, which was incorrect, full of typos, and incomplete (string cut off in mid-sentence), not to mention in English regardless of the application language.

Bugs come in many forms-you’re not just looking for the unlikely crashes, but the embarassingly obvious stuff. ;)

Software Tester must has these qualities—
1)He/she must observe the problem from both the side say user and programmer.
2)Must has good under standing with other team members .
3)Able to understand programmers view.
4)Once start testing, do not put it remain.
5)First test requirements of the user.
6)Before start testing first analysis the project like ;
technology using in project, all the flow etc……

#48 Rajesh Kumar

A manual tester would typically perform the following steps for manual testing:

Understand the functionality of program

Prepare a test environment

Execute test case(s) manually

Verify the actual result

Record the result as Pass or Fail

Make a summary report of the Pass and Fail test cases

Publish the report

Record any new defects uncovered during the test case execution

There is no complete substitute for manual testing. Manual testing is crucial for testing software applications more thoroughly. Test automation has become a necessity mainly due to shorter deadlines for performing test activities, such as regression testing, performance testing, and load testing.

Very nice article. If any body know please tell me about use of stubs and drivers in testing.

#53 Rajesh Kumar

Stubs – stubs r the dummy modules tht simulates the low level modules.

Drivers- drivers r the dummy modules tht simulate the high level modules.

#54 Santosh kumar

Thanks Rajesh, for providing me information about stub and drivers.

Hi, can anybody tell me about agile testing and when agile testing we do?.

#56 Arunthathi

Is age a criteria for entering into software testing industry ? ( Have a long gap since graduation)

#57 Rob

Hi,
I work for a company doing some basic testing with Mercury Loadrunner of web applications. I want to be a QA tester. Is there any particular language I should learn or book to get certified. I live in the U.S.A.

#58 Rajesh Kumar

what are the Qualities needed by a software tester?

A software tester must have intent of showing the product is not working as specified.
Software tester have the basic attitude of showing the presence of errors. He must have perspective of customers i.e he has to use the system as he is the client of the system. He has to strive for the quality.
1)He/she must observe the problem from both the side say user and programmer.
2)Must has good under standing with other team members .
3)Able to understand programmers view.
4)Once start testing, do not put it remain.
5)First test requirements of the user.
6)Before start testing first analysis the project like ;

Really it is very useful for the beginners.
I want to ask u a question
that i have an experience of 11 months but some times m not able to under stand the functionality & some technical points

#61 Rajesh Kumar

What is software ‘quality’?
Quality software is reasonably bug-free, delivered on time and within budget, meets requirements and/or expectations, and is maintainable. However, quality is obviously a subjective term. It will depend on who the ‘customer’ is and their overall influence in the scheme of things. A wide-angle view of the ‘customers’ of a software development project might include end-users, customer acceptance testers, customer contract officers, customer management, the development organization’s management/accountants/testers/salespeople, future software maintenance engineers, stockholders, magazine columnists, etc. Each type of ‘customer’ will have their own slant on ‘quality’ – the accounting department might define quality in terms of profits while an end-user might define quality as user-friendly and bug-free.

#62 Rajesh Kumar

We need Test Scripts because of the following points:

Acceptance testing is a complex and painstaking process that requires great attention to detail in order to ensure that the software is adequately exercised and that it meets the original requirements.
The objective of testing is to answer a binary decision: does the system pass the test or not. To make that decision there must be a defined result that must be achieved for each specified test ; and for the overall system there is usually an acceptance level defined in the contract which defines what number of individual failures may be acceptable.
To decide whether a test has been passed, there must be clear criteria that it must meet. This may be a value or set of values to be displayed on a screen, some results printed out, some specific changes in a database etc. In some cases it will be easy to check that the necessary result has been achieved (e.g. a picture on a screen) in other cases an extra action might be required (e.g. printing out the before and after state of a database record).

In order for overall testing to be accurately carried out, there will usually be a need to set up base data – perhaps by conversion of some existing computer data. Where this data can be set up and manipulated by the system it would be usual to use the system to do so – in fact to define the set up process as part of the overall test sequence.

To ensure that the correct steps are carried out, and in the correct sequence, it is important to put the process in writing. Where the sequence of the tests is important, for example where one sets up data for another, it is particularly important to have a defined “running order”.

The function of the test script is to define what input should be made to the system, and what output should be received. Usually the output will simply be text or perhaps a graphic on a workstation screen, sometimes there may be a printed report of some nature. A formal script defines (or identifies) several things:

Any data which should pre-exist and on which this test will rely, which may have been input by an earlier step in the script or crated by an entirely separate process – this data may be data held in the computer memory, a simple data file or a set of records in a database;
The steps that must be taken to run the test – for example keyboard input. This may of course be quite complex like filling in a long form defining a ship and its cargo capacity/facilities.
Any data that is created by the test, with steps to take to check that it has been properly created. In some instances this will be the next step in the test sequence, in others it will require the use of a separate piece of software to (say) examine a database.
The “pass” criteria which will be applied to the test.

A most important criterion for a test script is that it must be repeatable. Provided the environment is set up correctly, the test should produce the same result each time it is executed. But please note the dependence on the environment – usually data but potentially other factors as well such as computer or network configuration.

There is a risk of “false negatives”, i.e. tests said to have been deemed to have failed but where the failure is due to extraneous errors. For example, there was an error in the script and the “pass” criteria was not obtainable, there was a mistake in typing in data (say a wrong selection of “yes” or “no” – simple but devastating) or required pre-set data did not exist (the tests had been run out of sequence). It is of course also possible to make a mistake in the “pass” criteria – hence the script is faulty not the system.
All “failed” tests should be investigated to establish a reason for failure. Because of the complexity of testing, in many cases it is a “false negative”, and the root cause needs to be identified so that the test can be re-run properly. Occasionally investigations will indicate a “false positive” from another test, which had apparently passed but the system had failed to carry out some action or other during that test on which this test depended. Whilst the result might be still one test that failed (albeit a different one) it may affect the classification of the failure (and hence overall acceptability). On the other hand it may again simply be that the test script for that test failed to ensure that the action was carried out – i.e. a script error not a system error. There are then a string of tests to be repeated, or if time is not available, discounted.

#63 Rajesh Kumar

When to stop Testing
One of the most difficult questions out of the field of software testing is: “When is a good point to bring the test to an end, and are you ever through?” There are several reasons why it is difficult to find a good answer. Once more psychology plays an important role, especially if the ending condition is defined before the tests are started. Furthermore it can be assumed that — if the program is not very tiny — there is always one more bug. In other words, it is basically impossible to write a bigger, faultless program. A rule of thumb that can be used is that you should not stop testing as long as you keep finding bugs fairly regularly. On the other hand, if you never start selling your product, you will sooner or later run out of business. So despite the danger of an image loss due to annoying faults of your program which you did not find, you have to start marketing your product.
These considerations lead to the most likely common and nevertheless absolutely senseless ending condition: testing ends after a certain period of time has elapsed. In other words, the tests end on a fixed date. The uselessness of this condition is buried in the human’s purposeful behavior. A tester will normally not do his best if he gets a goal like “test n days” or “test until you cannot find any bugs anymore”. Those conditions share a similar weakness. For instance, given the last one, the tester will unintentionally run tests which are less likely to detect a bug, instead of doing good, intelligent, and destructive tests.

A better goal would be “find n faults”, but even though it is far away from perfect, it contains the following risk: How do you find a good approximation for n? If it is too low, several mistakes will not be found; and if it is too high, psychological problems have to be faced again. If the tester gets the feeling that he is unable to fulfill the given goal, he will get frustrated, and the quality of his tests will drop significantly.

Most likely, the best way out of this dilemma is to commit an external institution with the tests’ implementation. This step has several advantages like a healthy and productive rivalry, increased motivation on both sides, a reduced influence of the developers on the testers, normally a higher qualification of the testers, and the constraint to write a better documentation about everything done.

I am a fresher in testing and I have some queries -Is it necessary to have some coding knowledge to be a good tester? if yes which is most common scripting language tester preffer.

#75 rajashree

Hi
I am fresher in testing and working in small organization as manual tester. there is no any senior to me. So I cant measure my work and cant find way how to improve to be a good tester. If u pls see how I work (here I am mentioning in brief), I think u can suggest me something helpful. I write test cases only for failed testcases. I first run the testcases thinking in my mind and when it find failed then write it with prority,status, in nsame report (My report contains fields as srno., object, steps, actual result, expected result, pass/fail, prority, Developer’s status(done /not done/rejected/postponed/enhancement), Developer’s comment, Tester’s status(new/open/reopen/close)) .I cant understand what is the use of writing testcases which are passed. Pls give me ur advoice how can improve my skill, which scripting language should i learn?

#80 Preeti

I am very new to software testing, I have worked in a company for nearly 7 months. I have confusion towards knowledge that I should acquire. Till now I have done only manual testing:- Functional, Usability, Compatibility. My question is shall I go for learning some automated testing tool right now or shall I keep my self pushing into this areas more and more so that I make my base strong. I will really appreciate, If any one can guide me how should I design my career in testing, i.e what to do , when to do and things that I should not do.

#81 Tester

Hi ,

To every readers of the site…

* If u need to prove urself to be a good tester,u should have a “Test to break attitude”.if u mention tis in ur resume it ll attract the selector of the interviwer.

@ preeti

hi dude,

First u should have a thorough knowledge on manual testing.. which is hard when compared to automation,
so 1ce u think tat u r strong in manual , next u can move on to the automation & u ll feel easier to learn it.

thank u for the post vijay.
