In the software testing lifecycle, after what phase does test execution typically occur?

Test execution typically occurs after the test design phase in the software testing lifecycle. During the test design phase, testers create the test cases and prepare the necessary documentation based on the requirements and design specifications of the software. This includes defining what needs to be tested, how it will be tested, and the criteria for success.

Once the test design is complete, testers move into the test execution phase, where they run the tests that have been planned and designed. This is a critical phase because it is where actual testing happens, and results are generated to determine if the software behaves as expected. The test cases developed during the design phase guide this execution, ensuring that the software is thoroughly evaluated for defects and performance issues.

The other phases mentioned are important parts of the overall testing process, but they occur either before or after test execution. Test planning involves determining the testing strategy and scope, while test closure focuses on finalizing and reviewing testing results after execution has concluded. Test analysis, which might involve reviewing requirements or user stories to understand what needs testing, is also conducted prior to test design.
