Smoke testing _BVT(Build Verification testing)
Sanity testing _BAT(Build Acceptance testing)
BVT:- 10 to 15 is critical test cases.
BAT:- 85 to 90 of test cases will be BAT.That is non crtitical test cases.
BVT:-Once navigation tests are complete execute the tests that are termed critical. That means a set of test scenarios/cases must be identified as critial priority such that if these tests do not work the product does not get acceptance from the test team. Usually this will be 10 to 15 of the total test cases.
BAT:- The next job is to go thru the rest of the 90 of test cases and the respective test steps one by one and then actually performing the steps on the software roduct.
