Software applications are becoming more complex, demanding a robust test process for all critical features due to technological advancements. In software testing, verification and validation are essential to ensure the proper functioning and performance of the software applications. Quality Analysts (QA) and software developers should have reasonable control and understanding of the testing process to have a robust test approach throughout the Software Testing Life Cycle (STLC).
In STLC, there are different phases, which have respective goals and deliverables. Among these, test planning and test case development are the two crucial phases. Comparing a test plan vs. a test case, the 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. They are often used interchangeably but hold significant differences that must be understood.
