STLC – Software Testing Life Cycle

Testing software is not a single activity wherein we just validate the built product, instead, it comprises a set of activities discharged throughout the application lifecycle. The software testing life cycle or STLC refers to all these activities discharged during the testing of a software product.

Phases of STLC

• Requirement Analysis – This phase involves analyzation and validation of the necessary documents.
• Test Planning and Control – Test planning is considered as one of the most important activities in the test process. It includes defining the test specifications with a view to achieving the project requirements. Whereas, test Control involves continuous monitoring of test progress with the set plan.
• Test Analysis and Design – This phase includes analyzing and reviewing requirement documents, risk analysis reports, and other design specifications. Besides this, it also includes setting up test infrastructure, creation of high-level test cases and creation of traceability matrix.
• Test Case Development – After that, this phase includes the actual test case creation.
• Test Execution – This phase involves manual and automated test case execution. During test case execution any deviation from the expected result leads to the creation of defects in a defect management tool or manual logging of bugs in an excel sheet.
• Exit Criteria Evaluation and Reporting – This phase involves analyzing the test execution result against the specified exit criteria and the creation of a test summary report.
• Test Environment Setup – This phase involves the creation of a test environment closely simulating the real-world environment.
• Test Closure – This phase marks the formal closure of testing. It includes checking if all the project deliverables are delivered, archiving the testware, test environment and documenting the learning.
