This issue is currently blocked by Unity as they did not implement this yet.
If you'd like to see this implemented here, cast your votes at https://feedback.unity3d.com/suggestions/expose-unit-test-coverage-information-in-unity-test-tools
Edit: above link died, unity closed feedback website in favor of forums, but look at the following good news (first comment in this issue)
- Make sure Code Coverage plugin is installed
- Add coverage report generation to test scripts
- Add coverage report as an artifact
