Hi,

Testing lifecycle is not permitted to certain stage of development. The testing phase varies from company to company. In some companies, the QA department is involved from the requirements stage. In some other, the QA department is restricted to top level testings itself.

The testing type differs according to the phase of the development life cycle. Design reviews will be done on the software designs of the developer by the software tester. The testing done on modules of the code written is called unit tests. After the first release of the project, functional testing is carried out. All the bugs are reported and a next release is given with all the bugs fixed. Regression testing is done on the code released. Performance, stress testing is carried out on the application to ensure high quality.

The beginning of the testing in the lifecycle is not restricted to any particular stage.

Regards,
Divya.

Hi Sampada,

The testing phase begins at the time of some development of the project. It can be a black box testing or a white box testing.Testing plays a major role in the software development.At least 70% time of the project is consumed in testing a project.

Its role starts in the intial stages of the project development.

Thanks
Ashlee

I SDLC has 5 steps and the testing can happen at any stage. But if answering to an interview it does happen during designing process itself.

Although testing varies between organizations, there is a cycle to testing:

1. Requirements Analysis: Testing should begin in the requirements phase of the software life cycle(SDLC).
2. Design Analysis: During the design phase, testers work with developers in determining what aspects of a design are testable and under what parameter those testers work.
3. Test Planning: Test Strategy, Test Plan(s), Test Bed creation.
4. Test Development: Test Procedures, Test Scenarios, Test Cases, Test Scripts to use in testing software.
5. Test Execution: Testers execute the software based on the plans and tests and report any errors found to the development team.
6. Test Reporting: Once testing is completed, testers generate metrics and make final reports on their test effort and whether or not the software tested is ready for release.
7. Retesting the Defects
