Build Verification Testing (BVT) and Build Acceptance Testing (BAT) might sound similar, but they are different in several important ways. BVT, sometimes called smoke testing, is a preliminary test to check if the main functions of the software work as expected after a new build. This test is quick and focuses on finding show-stopper bugs that could prevent further testing. The goal is to ensure the build is stable enough for more detailed testing. BAT, on the other hand, is a more comprehensive test to decide if a build is ready to be tested by the QA team. It involves a deeper check of features and is often used to verify that the build meets the criteria set by the project’s stakeholders. BAT ensures the build aligns with the business requirements before it undergoes detailed testing. In summary, BVT is about quick checking for stability, while BAT is about ensuring the build meets the requirements for further testing.
