Software Testing Life Cycles

Software Testing Life Cycle (STLC)

The Software Testing Life Cycle (STLC) is a structured approach to software testing that describes the various phases and activities required to ensure the quality and reliability of a software product. Although the specific methods may vary, common phases of STLC include:

Requirements Analysis: Understand the project requirements, objectives, and constraints to determine test scope.

Test Plan: Create a comprehensive test plan that outlines test strategy, objectives, scope, resources, schedule, and start/stop criteria.

Test Case Development: Create detailed test cases based on requirements and design documentation. These test cases include the steps to be performed, the expected results, and any required test data.

Test Environment Setup: Prepare the hardware and software environment required for testing, including installing and configuring test tools and infrastructure.

Test Execution: Execute test cases according to the test plan and document the results. This phase may include manual testing, automated testing, or a combination of both.

Bug Tracking: Records all bugs found during testing, including details about the problem, its severity, steps to reproduce the problem, and the environment in which the problem occurred. Bug

Resolution: Work with the development team to troubleshoot and resolve reported bugs. This may include re-inspection to ensure corrected defects have been adequately addressed. Regression

Testing: Repeat: previously run test cases to ensure that recent code changes or bug fixes do not introduce new issues or regressions.

Test Completion: Evaluates the completion criteria specified in the test plan to determine whether the test objectives were achieved. This includes writing a final test report, summarizing testing activities, and documenting results for future projects.

Test Reporting: Create reports that convey test progress, including metrics such as test coverage, defect density, and pass/fail rates. These reports help stakeholders make informed decisions about the release readiness of the software. Throughout the STLC, collaboration between the testing team, development teams, and other stakeholders is key to ensure that testing efforts are aligned with project goals and priorities. Additionally, continuous feedback and iterations can occur as new information emerges or project requirements evolve.
