| S. No. | Phase | SDLC – Software Development Life cycle | STLC – Software Test Life Cycle |
| 1 | Requirements Gathering | Requirements gathering is done by business analyst. Development team analyse the requirements from the design, architecture & coding perspective. | Testing team also review & analyse the requirements. Testing team identifies the testing requirements like what types of testing will be required and review the requirements for logical functional relationship between various features / modules, so that any gaps can be caught at an early stage. |
| 2 | Design | Technical architect works for the high level & low design of the software. Business analyst works for the UI design of the application | Here, test architect generally the test lead/manager, does the test planning, identify high level testing points. Basically, requirement detailing is done in this phase. |
| 3 | Coding or development | Development team does the actual coding based on the designed architecture. | Testing team write the detailed test cases. |
| 4 | Testing | In SDLC, actual testing is carried out in this phase. It includes unit testing, integration testing & system testing etc.. | 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. Testing of test cases & test plans i.e. is basically review of test cases, test scenarios etc.. |
| 5 | Deployment | Application is deployed on production environment for real end users. | Final testing and implementation is done is this phase and final test report is prepared. For software / application deployment is basically, when it is installed for real use. So, this way, STLC, deployment would be when test when test cases getting used i.e. execution of test cases. |
| 6 | Maintenance | Basically, it includes, post production / deployment support & enhancements. | Most of people say – Maintenance testing is carried out in this phase. Updation & maintenance of test plans, test case required for the testing of support requests & enhancements as a part of maintenance. |
