Steps to reproduce:
# Unzip attached project
# Run tests from command line:

??Unity.exe -projectPath test-framework-callbacks -batchmode -testPlatform editmode -runTests??

If RunFinished callback was executed successfully, you should be able to find "RunFinished works" in the Editor.log. Notice that log entry is not in the Editor.log.

Extra steps:
# Disable CompilationPipeline.RequestScriptCompilation(); call in NewTestScript.cs (this will make it so that domain reload doesn't happen during test run)
# Run tests using command line again
# Inspect the Editor.log and notice that now you can find "RunFinished works" entry
