Base case walkthrough on each build could save you time

When you have a set of test cases to execute, and especially across various platforms, it’s very time-efficient to do a base case run before you start officially marking test cases as pass/fail. In testing lingo, this is classified as smoke tests or sanity tests. It helps with catching obvious bugs early, and if it’s a base case then it’s a high priority. Everyone saves time with back and forth, and with having to re-execute test cases when the new build does arrive. Ideally, this is done with automated tests to save even more time in the long run.
