The Software Testing Life Cycle (STLC) outlines a series of tasks to ensure software quality, including requirement analysis, test planning, test case development, setting up a test environment, test execution, and closing out the test cycle. During requirement analysis, testers analyze requirements from a testing perspective to identify testable requirements and understand them fully. In test planning, resources, the test environment, limitations, and schedule are decided. Then in test case development, test cases and scripts are created, verified, and updated using prepared test data.
