Cannot get unit tests stats due to missing test logs either in derived data or result bundle path

I'd like to gather the test coverage statistics for a given target in a project. The Xcode version that I use is 12.4. I did run tests for a project via xcodebuild command:

$ xcodebuild test -scheme Demo -sdk iphonesimulator -destination 'platform=iOS Simulator,name=iPhone 11 Pro,OS=14.4' -resultBundlePath ~/Demo/result

According to the blog post mentioned in the README file, there should be .xcactivitylog log generated at the result bundle path, however, with Xcode 12.4, it is not. There's a .xcresult file instead.

I also checked the derived data and same results.

I tried to simply parse the build activity log, but no data about unit tests has been found:

$ xclogparser parse --project Demo --reporter html

Could you please help me to figure out the way to get the unit tests coverage stats? 🙏

I will gladly update the documentation if needed 😊

Start with the README's test-logs section and reproduce the reported xcodebuild command using Xcode 12.4. Compare the generated .xcresult bundle with the expected .xcactivitylog inputs and inspect the parse command's available handling for each; done means documenting a working coverage-statistics path or clearly recording the limitation.
