STLC stands for Software Testing Life Cycle. It is a set of activities or phases that are followed during the testing process of a software application. The main purpose of STLC is to ensure that the software being developed undergoes thorough and effective testing before it is released to the users.
The typical phases of STLC include:
- Requirement Analysis:
- Understand and analyze the software requirements.
- Test Planning:
- Develop a detailed test plan, including test objectives, scope, resources, schedule, and testing activities.
- Test Case Development:
- Create detailed test cases based on the requirements and test plan.
- Test Environment Setup:
- Set up the test environment with the required hardware, software, and network configurations.
- Test Execution:
- Execute the test cases, report defects, and collect test results.
- Test Closure/Sign-Off:
- Analyze test reports, defect reports, and evaluate exit criteria to decide whether testing is complete.
