When files changes in watch mode, coverage info doesn't update.

To Reproduce

Steps to reproduce the behavior:

Run jest --watch --coverage, updates a file, see that no new coverage info gets updated.
Press 'a' to run all tests in watch mode, no coverage info shows up. @stipsan

Expected behavior

Coverage info shows up when I edit a file after starting watch mode, and when I press 'a' to show all tests.

I am on Jest v25.27 and I still see this bug.

Even if I empty the coverage directory, it still only shows coverage of one file (always the same file!)

@chenesan Are you sure this has been fixed, because it seems not...

Hi @rmcsharry, My fix is on jest v25.5.4.
I only fixed the case that when test files change, jest will show the coverage of related source code, so this may not be your use case 😓
By the way, it seems that this issue closed before I fix it in #9769 , so I'm not sure if the problem is totally gone.

@chenesan Thanks for the prompt reply. After I stopped and started the watcher a few times, it started working again and reports coverage correctly. Very odd. Let's hope it does not return. Maybe it was a cache issue.
