Test Plan vs Test Case: Key Differences

Test Plan vs Test Case are two crucial phases in Software Testing Life Cycle (STLC). A test plan is a written document that details the test strategy, scope of testing, resources, and others. On the other hand, test cases are the comprehensive instructions or steps needed for testing and validation of particular features of software applications. The key differences between them include their definition, aspects, focus, scope, intended audience, duration, sections, dependency, uses, frequency of use, changes over time, and documentation level.
