Purpose of video is to automate a C++ test, and ensure that only branches where the tests are successful can be merged onto main, for better collaboration. In this example the branch settings enforces merge requests.
Branch being merged on the demonstration is "last_branch".

First half of the video is running a test case that will fail (notice the '+10'). Because of my branch settings failed tests cannot be merged onto main.
The second half of the video is running a test case that will pass, which successfully merges onto main.
