Software development life cycle(SDLC) and Software Testing Life cycle(STLC) go parallelly.
| SDLC (Software Development Life cycle) | STLC (Software Test Life Cycle) |
|---|---|
| SDLC is Software Development LifeCycle, it is a systematic approach to develop a software. | The process of testing a software in a well planned and systematic way is known as software testing life cycle(STLC). |
| Requirements gathering | Requirements Analysis is done is this phase, software requirements are reviewed by test team. |
| Design | Test Planning, Test analysis and Test design is done in this phase. Test team reviews design documents and prepares the test plan. |
| Coding or development | Test construction and verification is done in this phase, testers write test cases and finalizes test plan. |
| Testing | Test Execution and bug reporting, manual testing, automation testing is done, defects found are reported. Re-testing and regression testing is also done in this phase. |
| Deployment | Final testing and implementation is done is this phase andfinal test report is prepared. |
| Maintenance | Maintenance testing is done in this phase. |
