The document discusses the Software Testing Life Cycle (STLC) which consists of 6 phases to ensure software quality goals are met. The 6 phases are: 1) Requirement Analysis where QA interacts with stakeholders to understand requirements, 2) Test Planning where a test plan is created outlining testing activities, efforts, and costs, 3) Test Case Development where test cases and data are created and reviewed, 4) Test Environment Setup where testing conditions are decided, 5) Test Execution where testing is carried out based on test plans and cases, and 6) Test Closure Activities which are done after product delivery and include ensuring test completion and archiving work products.
