I am preparing an Ant package to move code to production. However, many of the existing orgs tests are very out of date and are failing. At this point, my only option is to select tests that cover the code that I'm deploying since I cannot fix all of the tests before going to production.
Is there a way using migration tool to enforce production-like test coverage rules without running all tests? My challenge is ensuring that the tests I manually select to run on deploy adequately cover the classes I am deploying.
