This commit adds tests to verify the behavior of the gitDirectoryHelper.prepareExistingDirectory() function when the submodule status is either true or false.
The test cleanWhenSubmoduleStatusIsFalse verifies that the function will clean the directory when the submodule status is false. The test sets up a mock implementation of git.submoduleStatus to always return false, writes a file to the repository, and then calls gitDirectoryHelper.prepareExistingDirectory(). The test verifies that the directory is cleaned and that git.tryClean() is called.
The test doesNotCleanWhenSubmoduleStatusIsTrue verifies that the function will not clean the directory when the submodule status is true. The test sets up a mock implementation of git.submoduleStatus to always return true, writes a file to the repository, and then calls gitDirectoryHelper.prepareExistingDirectory(). The test verifies that the directory is not cleaned, that the file and .git folder are present, and that git.tryClean() is called.
These tests ensure that the function behaves as expected based on the submodule status.
When trying to list local branches to figure out what needs cleaned up during runs on non-ephemeral Actions Runners, we use git rev-parse --symbolic-full-name to get a list of branches. This can lead to ambiguous ref name errors when there are branches and tags with similar names.
Part of the reason we use rev-parse --symbolic-full-name vs git branch --list or git rev-parse --symbolic seems to related to a bug in Git 2.18. Until we can deprecate our usage of Git 2.18, I think we need to keep --symbolic-full-name. Since part of the problem is that these ambiguous ref name errors clog the Actions annotation limits, this is a mitigation to suppress those messages until we can get rid of the workaround.
* Adding the ability to specify the GitHub Server URL and allowing for it to differ from the Actions workflow host
* Adding tests for injecting the GitHub URL
* Addressing code review comments for PR #922
