@Bibek,

Could be n-tier applications as well.

Eg, following are the different tiers you can see,

1) Presentation GUI -> HTML, Windows forms, etc.
2) Presentation Logic Tier -> The Web Server Side - IIS (VBScript,JScript, Web Forms, C#, VB.net, etc) Produces: (HTML, XML,

WML, DHTML, etc), Proxy Tier (SOAP, CORBA, RMI, DCOM, etc).
3) Business tier -> Business Objects and Rules, Data Manipulation and Transformation into Information, Could be deisgned in a stateful manner.
4) Data Access Tier -> Interfaces with the Database, Handles all Data I/O, Made to scale, usually stateless.
5) Data Tier -> Storage, Query & Storage Optimization, Performance (Indexing, etc).

Regards,
VijayD

@Vishal,

Quality Center can be used to Track the Following Integrated Testing Process:

1) Specifying Requirements: Identify and validate the functional and performance requirements that need to be tested

(Requirements Planning).
2) Planning Tests: Plan and confirm which tests need to be performed and how these tests must be run (Test Plan).
3) Running Tests: Organize test sets, schedule their execution, perform test runs, and analyze the results of these runs

(Test Lab).
4) Tracking Defects: Add defects that were detected in the application and track how repairs are progressing (Defects

module).
5) Generating Reports: Module Specific Report or General report can be generated any time during the testing process from each Quality Center module, using default or customized settings (Dash Board).

1) Requirements:
Requirements describe in detail what needs to be tested in your application and provide the test team with the foundation on

which the entire testing process is based.In Qualtiy Centre you can:

a) Define and View Requirements:
You can Add Requirements, Child Requirements and additional child Requirements which can be viewed in the Tree View and Grid

View and apply Filters. You can zoom in and out of the requirements tree and also display or hide numeration.

b) Modify and Track Requirements:
You can drag drop, rename, change properties and delete a requirement.

c) Convert Requirements:
Once Finalised Requirements can be converted into Tests using Automatic conversion Method.

d) Link Requirements:
You can Later link Requirement to Tests and Defects.These Links can be Direct and Indirect.

2) Test Plan:
Test Plans in QC can be used to outline the testing strategy for achieving your goals .
After you have determined your testing goals you can use QC to :

1) Build a test plan tree:
A Test Plan tree hierarchically divides your application into testing units, or subjects. You define tests that contain

steps. Each test step, specifies the actions to be performed on your application and the expected result.

2) Automation:
Once decided on which test to automate you can generate a QTP or a Winrunner script ,Upload it and Link it to the

Corresponding Manual Test case. The Various stages of Automation are tracked in QC are as the follwing ‘Automation Status’ :
a) Suitable \ Not Suitable: The manual Testers mark a Test case as Suitable if it can be Automated.
b) Design: Going through Automation.
c) More Info Required: Some Details for Automation Missing .
d) For SME Approval: Automated and Waiting for SME’s Go Ahead for Execution.
e) Operational: Ready for Execution, Automated.
f) Reject: Descoped while Automation.
g) Repair: Maintainence of a script in case of changes.

3) Create and View Requirement Coverage:
In the Test Plan module or in Requirements module, you create requirements coverage. A test can cover more than one

requirement, and a requirement can be covered by more than one test. Use the Coverage Analysis view in the Requirements

module to analyze the breakdown of child requirements according to tests coverage.

3) Test Lab:
Running tests is the core of the testing process.

1) Define Test Sets:
Group the Various Tests into Sanity Tests, Normal Tests, Positive checks test, Negative tests, Advanced Checks, Smoke Tests

and Regression Tests.

2) Add Tests to a Test Set :
A One Step Process to Associate Tests to a Test Set in the Test Lab Module. A Test Set In QC has the following Properties:
a) Details: This property can be used to list the details of a Test set.
b) Attachments: Documents, reports and Files for a Particular Set can be attached.
c) On Failure: Set rules for automated runs in case of Failures.
d) Notification: Mails can be sent to the concerned User Groups in case of Different Types of Failures.

3) Schedule Test Runs Automatically:
A Test Set can be scheduled for a Specific Day, a Specific Time and on a Specific Machine. Unattended Runs can be scheduled

and results later Analyzed.

4) Defects:
Locating and repairing defects is an essential phase in application development.

1) Tracking Defect:
In Quality Center project defect is tracked through these stages: New, Open, Fixed, and Closed. A defect may also be Rejected

or it may be Reopened after it is fixed.

2) Add Defect:
A Defect can be assigned the following Significant Properties on QC:
a) Details: The Various Detailsa as to which Project,Component and Phase does the Defect belong to.
b) Assigned to:It can be directly assigned to a user, who gets notified throgh a mail.
c) Severity: Categorize the defect as Urgent,High,Medium,Low.
d) Attachments: Attach snapshots, logs or other files specific to that defect.
e) Comments: Add comments as and when a defect moves from one stage to other and add Resolution Details.

3) Emailing Defects:
Defects can be mailed to the User whom it is raised by, the user whom its assigned to and the other e-mail I.D’s.
4) Linking Defects:
Defects can be linked to various Tests and in turn to requirements.
Reports, Graphs and Dashboard:
You can generate reports and graphs at any time during the testing process from each Quality Center module, using default or

customized settings.

5) Generating Reports:
Module Specific Report or General report can be generated any time during the testing process from each Quality Center

module, using default or customized settings.

1) Generating Graphs:
Graphs of the following types can be generated:
a) Summary.
b) Trend.
c) Progress.

2) Generating Live Analysis Graphs:
You can create Live Analysis graphs to provide a dynamic quick visual overview of all the tests in a test subject folder, or

test sets in a test set folder.

3) Filters and Sorts:
Apply filters and sort conditions, and display information according to your specifications,Save your settings as favorite

views and reload them as needed.

4) Dashboard:
a) Support for all QC platforms (Solaris, Linux, WL, WS)
b) Support for clustering and load balancing
c) Support for QC and QCD on the same machine

Hope this helps.

Testing can also be categorized based on how it is executed. Execution could be in the form of verification or static analysis or it could be validation or dynamic analysis. Verification and validation can be categorized further according to how it is done.

Hi Vijay and everybody, I want to know is there any easy tool to track the test cases? and now I am doing manual testing for web applicaton so I like to automate that. I have tried to record the web application by Winrunner, QTP etc.. but I am getting an error like “Object not found” something like that, this too after learning the application objects by winrunner. So please send me the steps to automate the web application with an example. I will be waiting for your reply.

Thanks,

hi all,
Is there any need to perform security testing on client server based application.
Please comment.

#35 karthik Jayaraj on 06.17.08 at 8:51 am

There are numerous differences in Client-Server and Web application architecture. As a tester if you are testing Web applications, it is important to understand what Client-Server architecture is and how Web is different from traditional Client-Server architecture.

Web is a specialized version of client server network, but it has got noticeable differences. In client server network, computing resources are conserved by delegating complex and time consuming task to powerful, expensive computers called server. These server machines are much more powerful in terms of large storage and computing power. They do all the computing and delivers result back to the machines called client over a communication path. Thus client-server architecture comprises of server, client and communication path connecting them.

If you see at the lower level, client server architecture is not that simple. In order to connect two computers, you need network level protocol, you need proper software at client side and server side to send and receive data over network. You need to take care of data loss during transmission, bandwidth issues, dropped connectivity etc. Most of these issues are already addressed by protocols like TCP/IP, UDP, ARP etc. and developers face very little problem in implementing them. These protocols are backbone of the client server architecture.

WWW was developed on top of existing client server architecture. It came into existence as a replacement for FTP and email as a mechanism of sharing files and data. New development in servers to handle more requests, new client software to connect and browse resources on server; new development like HTTP, HTML etc fueled the growth of Web. Main component of the Web architecture is the Web Server, which can serve request from any client. Initially, web started serving static content and soon it was explored for the possibility of doing much more than just static content.

Even though Web is built on top of client server, there are noticeable differences. For example

Web is a special case of client server architecture in which fat clients are used to communicate with the server using variety of protocols and standards like HTTP, HTML, XML, SOAP etc.
In client server architecture, both client and server exist within the walls of a single company, thus operates in a protected environment. Clients in that case become the trusted user. Web is different, since client can connect server from anywhere thus not a single connection can be treated as trusted.
Because client server is typically within a company’s firewall, issues related to security are not as important as in Web applications.
In client server architecture, clients are controlled as in who can access, how clients will communicate and use server’s resources etc. In Web, mostly anyone with a browser can connect to the Web.
In client server architecture, every client is known; every request received by server will have information on who originated this request. In Web, users are anonymous thus pose a greater security risk.
Web gives more opportunity to malicious users to tamper data at the client side as well as at the network level. Chances of data being tampered in the traditional client server architecture are much lesser as compare to Web.
Number of clients that can be connected to the server is predictable and can be controlled in the traditional client server, but it can not be controlled in the Web.
Clients are much more controlled in client-server. Which OS they will use, which platform they will run on, what browser will be used every thing can be controlled. In comparison to that, nothing can be controlled in Web.
Because of the fact that both are different, testing applications in client server, or web will also be different. The main areas where the testing gets affected can be summarized as:

Business Logic: Mostly in the cases of Client-Server client side business logic needs to be tested which is mostly not needed in for the web-based applications.
Platform / OS Dependence: The web based applications are O/S independent; they just need to be tested on different browsers. The Client-Server applications depend upon the Platform/ OS used, which accentuate their testing on different Platforms and OS.
Scalability: Web based Application have to be tested for performance against thousands of simultaneous users. This number will be considerably less for Client Server application
Security: This forms an integral part of web based applications but it might be relaxed just a bit for Client Server applications. The reason for this relaxation is based on the fact that the in case of Client-server interaction is taking place mostly between the trusted/known sources which is not the case for web based applications.
In a nutshell it can be stated that although web-based applications are a special case of client-server applications, yet their testing differ in many areas. All the areas identified above need to be addressed adequately in your testing, specially security since every client connected in the web environment is a potential threat to the system.

Hello,
I an looking for job in SQT. I have done BSc(Maths) and Diploma in Computer Application Program. Due to some problem I had to work in a domestic call center. Now I am pursuing MBA from ICFAI University through distance learning and have knowledge of some of the SQT tools like WinRunner, Load Runner, QTP ect. But I cud not get a job as a Software Tester. How should I prepare myself for the interviews in this particular field. Should I do MBA in IT and pursue a diploma in SQT? Will that help to get a good job? Which institute is good for SQT course and of course job assistance is also important? Please help and reply me soon by e-mail as I am confused to take the right decision.
