What is Build Validation?
Build Validation test or Build Verification test is a set of tests that are executed on a new build to verify that the build is testable before the build is released to the independent testing team.
Scope of Testing:
The Build Verification Test is initiated before a complete test run because it lets developers know immediately if there is a show shopper defect associated with the build in order to save the test team's effort to test an unstable build.
The build acceptance test is usually a short set of tests not exhaustive which tests the mainstream functionality of the application/product. Any build that fails the build verification test is rejected and testing is continued on the previous build if exists.
