Let’s explore the first tutorial from “The Ultimate Guide to Automation Testing” series!!

What is Automation Testing?

If a software can do anything then, why can’t a software test a software?

Does this statement sound logical to you?

If yes, then congratulations, you are now thinking about Test Automation, which is the center point that we are going to discuss in this series of informative tutorials.

automation testing guide

Imagine yourself n the first day at your job as an SQA. You are presented with an application to be tested. It’s an ERP application containing 100s of forms and thousands of reports. You begin your exploratory testing by opening a form which contains around 50 different fields.

You try to enter random data in this form which took around 20 minutes. Then you press submit. Wolla!! An error message is shown which looks like an unhandled exception. You become very happy. You proudly note down the steps and report the bug in your bug management system. Great effort, you feel really confident and energetic. You continue the testing until the day ends and find some more bugs. “Amazing first day”, you thought.

Now comes the next day, the developer has fixed the issue and releases a new version of the build. You test the same form with the same steps and you found that the bug is fixed. You mark it fixed. Great effort. You have contributed to the quality of the product by identifying that bug and as this bug is fixed, the quality is improved.

Now comes the third day, a developer has again released a newer version. Now you again have to test that form to make sure that no regression issue is found. Same 20 minutes. Now you feel a little bored.

Now imagine 1 month from now on, newer versions are constantly releasing and on every release, you have to test this lengthy form plus 100 of other forms like this, just to make sure that no regression is there.

Now you feel angry. You feel tired

. You begin to skip steps. You fill around only 50% of the total fields. Your accuracy is not the same, your energy is not the same and definitely, your steps are not the same.

And one day, the client reports the same bug in the same form. You feel pathetic. You feel unconfident now. You think you are not competent enough. Managers are questioning your ability.

I have a news for you; this is the story of 90% of the manual testers out there. You are not different.

Regression issues are the most painful issues. We are humans. And we cannot do the same thing with same energy, speed and accuracy every day. This is what machines do. This is what automation is required for, in order to repeat the same steps with the same speed, accuracy and energy as they were repeated the first time.

I hope you get my point!!

automation testing a friend

Whenever such situation arises, you should automate your test case. Test automation is your friend. It will help you to focus on new functionality while taking care about the regressions. With automation, you can fill that form in less than 3 minutes.

The script will fill all the fields and tell you the result along with screenshots. In case of failure, it can pinpoint the location where the test case failed, thus helping you to reproduce it with ease.

Scenarios which require Automation

The above scenario is not the only case when you will need automation testing. There are several situations, which cannot be tested manually.

For Example,

  1. Comparing two images pixel by pixel.
  2. Comparing two spreadsheets containing thousands of rows and columns.
  3. Testing an application under the load of 100,000 users.
  4. Performance Benchmarks.
  5. Testing the application on different browsers and on different operating systems in parallel.

These situations require and should be, tested by tools.

Simple Example of Test Automation

When you are testing a software (on the web or desktop), you normally use a mouse and keyboard to perform your steps. Automation tool mimics those same steps by using a scripting or a programming language.

For Example, if you are testing a calculator and the test case is that you have to add two numbers and see the result. The script will perform the same steps by making use of your mouse and keyboard.

The example is shown below.

Manual Test Case Steps:

  1. Launch Calculator
  2. Press 2
  3. Press +
  4. Press 3
  5. Press =
  6. The screen should display 5.
  7. Close Calculator.

Automation Script:

//the example is written in MS Coded UI using c# language.
public void TestCalculator()

//launch the application
var app = ApplicationUnderTest.Launch("C:\\Windows\\System32\\calc.exe");

//do all the operations

//evaluate the results
Assert.AreEqual("5", txtResult.DisplayText,”Calculator is not showing 5);

//close the application

The above script is just a duplication of your manual steps. The script is easy to create and easy to understand as well.

What are Assertions?

The second last line of the script needs some more explanation.

Assert.AreEqual(“5”, txtResult.DisplayText,”Calculator is not showing 5);

In every test case, we have some expected or predicted result at the end. In the above script, we have an expectation that “5” should be shown on the screen. The actual outcome is the result that is displayed on the screen. In every test case, we compare the expected outcome with the actual outcome.

Same goes for automation testing as well. The only difference here is, when we do that comparison in test automation, then it is called something else in every tool.

Some tools call it as “Assertion”, some call it as “checkpoint” and some call it as “validation”. But basically, this is just a comparison. If this comparison fails, for E.g. a screen is showing 15 instead of 5 then this assertion/checkpoint/validation fails and your test case is marked as failed.

When a test case is failing due to an assertion then that means you have detected a bug through test automation. You must report it to your bug management system just like you normally do in manual testing.

In the above script, we have performed an assertion in the second last line. 5 is the expected outcome, txtResult. DisplayText is the actual outcome and if they are not equal, we will be shown a message that “Calculator is not showing 5”.

Automation Testing – A Cost-effective Method for Regression Testing

Automation costs are really higher initially. It includes the cost of the tool, then the cost of the automation testing resource and his/her training.

But when the scripts are ready, they can be executed hundreds of times repeatedly with the same accuracy and rather quickly. This will save many hours of manual testing. So the cost gradually decreases, and ultimately it becomes a cost-effective method for Regression testing.


This excellent tutorial can be summarized in just 7 points.

Automation Testing:

– Is the testing which is done programmatically.
– Uses the tool to control the execution of tests.
– Compares expected outcomes with the actual outcomes (Assertions).
– Can automate some repetitive but necessary tasks (E.g. Your regression test cases).
– Can automate some tasks which are difficult to do manually (E.g. Load testing scenarios).
– Scripts can run quickly and repeatedly.
– Is cost effective in the long run.

Here, Automation is explained in simple terms, but that doesn’t mean that it is always simple to do. There are challenges, risks and many other obstacles involved in it. There are numerous ways by which test automation can go wrong, but if all goes well, then the benefits of test automation are really huge.

Upcoming ones in this series:

In our upcoming tutorials, we will discuss several aspects related to automation.

These include:

  1. Types of automated tests and some Misconceptions.
  2. How to introduce automation in your organization and avoiding common pitfalls when doing test automation.

  1. Good article. I specifically need guidance on tool selection process. Can you help on this?

  2. Good article. Thank You

  3. Hi,

    Article was really helpful.Looking forward to read more articles on “Guide to Start Automation Testing on Your Project”…That would be very helpful to switch to automation.

  4. Nice Article. I need guidance on writing test scenarios in Behat. Can you help on this?

    Share any article with Behat, Mink & Selenium. How to use it with the project with examples?

  5. @komal: Thank you. For tool selection process, please wait for 4th Article in this series. The article name is “The tool selection process and comparison of various automation tools.”

  6. very good article specially for new comers who want to make their career in test automation field..i need a complete detail article about test automation in automotive industries.which tools are used and mostly which targets are needed test automation.thanks.

  7. @Koteshwari: Thank you

  8. Simple and to the point.
    Good Stuff.
    Waiting for more on it in advance level.

  9. @Komal: Thank you. Please wait for article number 4 in this series

  10. Indeed a good article, thanks for the effort you put to consolidate those basic steps together.

    It would be better if you add the tool name in the subject line which code is given as example (Selenium/QTP/RFT)

    The topic is not elaborate enough to justify the title. I mean guide to start automation should include a bit of manual test case , considering and filtering those for regression suite and then identify keywords, then prepare test data , then record and play/ script code then enhance those with programming logic and write reporting module , then outputs, then maintaince and debug … something like this. But maximum text covers why we need automation, advantages of automation etc.. Just a thought for improvement no other intention!.Correct me if I am wrong.

  11. I have started Test Automation using Microsoft Test Manager, MS Coded UI Test, and Visual Studio Tools. I am Looking forward to read more articles on the same.

  12. Pramod Mallick: Thank you for your feedback. This is just the first article in the series of 7 articles about test automation. Your questions will be answered in upcoming Articles.

  13. Pramod Mallick: Please see the comments on the top of automation script. The tool name is mentioned there. (MS Coded UI)

  14. I need little more information on working of Selenium. How to use it with the project with examples?Some good sources to get some hands on this tool(Sites information, Prerequisite for the same)

  15. Mohammad Saad:
    Thanks for your comments. I am eager to read next part of the article.
    If possible, cover the differences between coded UI and other tools.
    Example: QTP vs Coded UI – including technology, simplicity, cost, versioning, maintaing, compatibility, depedency etc..

    Pramod Mallick

  16. Thank you very much for this tutorial and initiative. I’ve started learning Automation Testing with OpenSource Selenium2 (WebDriver) requiring Java programming knowledge and now I’m trying to get familiar with UFT ver: 12.02 from HP (Unified Functional Testing) former-QTP that requires now knowledge of Visual Basic scripting. I’ve read all the comments above and now my questions are:
    1. Are MS Coded UI and Microsoft Test Manager related to UFT or are they totally different and require to learn other scripting languages?
    2.Which one’s better for WebApp and Mobile Testing?

    Thank you,

  17. @Luke: Thank you for your feedback. The answer to your first question is that MS Coded UI and MS Test Manager are totally different tools. These are created by Microsoft. UFT on the other hand is owned by HP. You need to learn either C# or VB.Net to learn Coded UI. MS Test manager is a test case and bug management tool so you don’t need to learn any programming language for that.

    The answer to your second question is described in detail in article number 4 “The tool selection process and comparison of various tools” which will be published shortly.

  18. @Pramod Mallicki These differences are described in detail in article number 4 “The tool selection process and comparison of various tools” which will be published shortly.

  19. Useful Automation Guide Indeed And thanks for it :)

  20. Mohammad, you’re doing great job. Welcome one and hats-off to STH. Hoping that your service will continue henceforth.

  21. One more thing it is fine as you said we need to introduce automation for project/product which we required more regression testing but I need to know about if project is small size and not much regression testing work then automation is feasible or not ? If yes then why or not then why ?

  22. @Keyur Makwana: Your question will be answered in article number 2 and article number 3 in this series. You will get to know that when you will need automation and when you can avoid automation all together.

  23. wt are the entry criteria for automation testing

  24. this is a fantastic article!! thanks saad and admin.
    Keep sharing .

  25. @Mohammad Saad Thank you for your prompt and clear answer. I’m looking forward for your upcoming articles.

    Thank You,

  26. Nice start to explain Automation in easy way from the scratch.

  27. Nice Article .I need some information for microsoft test manager.

  28. Thanks for this basic intro to automation, Mohammed. I look forward to your other articles.

    I hope that our wiki on test automation will also be useful (

    I will also be interested to see if you reference my 2 books on test automation! ;-)

  29. Great start!!! You explained automation concept so simply and precisely that I got it in first read. Please publish the remaining articles soon. I can hardly wait to delve deeper into this. I am itching to introduce automation at my work. I know a little bit about Selenium but there are so many other options as well that I know nothing about. I look forward to learning more about all the other tools.
