We dont run the entire test suit. Our last night test suit took 159 minutes to finish. We automated that in order to run every night. We need a 100% pass rate before we push to production. If you just do something you run those specific tests. If something else breaks due to that, it will be caught ( hopefully ) by the nightly tests. Imagine having to run the test suite 2 - 3 times a day. Your day would be wasted !
