Software Testing

 STLC stands for Software Testing Life Cycle, which is a systematic process for testing software throughout its development life cycle. The STLC process typically consists of several phases, each with its specific objectives and activities. The specific phases and activities may vary depending on the testing methodology and the organization's processes, but here is a general overview of the common types of phases in the STLC process:

1. Requirement Analysis:

   • Understand and analyze the software requirements.
   • Identify testable requirements.
   • Create a traceability matrix to link test cases to requirements.

2. Test Planning:

   • Define the overall test strategy and approach.
   • Identify resources, timelines, and budget for testing.
   • Develop a test plan document that outlines the testing scope, objectives, and deliverables.

3. Test Design:

   • Create detailed test cases based on functional specifications.
   • Develop test data and environment setup.
   • Identify and prioritize test cases based on risk and business impact.

4. Test Environment Setup:

   • Establish the necessary hardware and software infrastructure for testing.
   • Configure test tools and test data.

5. Test Execution:

   • Execute test cases according to the test plan.
   • Record test results and document any deviations from expected behavior.
   • Capture and report defects, if any, with appropriate details.

6. Defect Reporting and Tracking:

   • Report defects in a defect tracking system.
   • Prioritize and assign severity levels to defects.
   • Track the status of defect resolution and retest fixed defects.

7. Regression Testing:

   • Perform regression testing to ensure that new changes do not adversely affect existing functionality.
   • Automate repetitive and critical test cases for efficient regression testing.

8. Test Closure:

   • Summarize testing activities and results.
   • Prepare a test summary report.
   • Evaluate the testing process and identify areas for improvement.

It's important to note that the STLC process is not strictly linear, and activities in different phases may overlap or be iterative based on the development methodology being used (e.g., Agile, Waterfall). Additionally, organizations may customize the STLC process based on their specific needs and requirements.
