How to show the unit tests coverage window in JetBrains Rider 2025.1.4

How can I show the unit tests coverage window in JetBrains Rider 2025.1.4?  In settings, I have it configured to be shown automatically on the first run of test coverage.  But that does not happen.  When I click the Coverage button on the right side of the main window, the panel shown only contains an option to “Import a report collected in CI from disk”.

dotCover is working.  I can for example highlight the covered code in code files.

Hello Simon, 

Thanks for contacting Rider support. Regarding this issue, could you please try the following first:

1. Clear Rider caches via File | Invalidate caches => Invalidate and restart?

2. Go Rider settings | Plugins, disable and re-enable dotcover plugin

If the issue persists, please:

  • Provide screenshots demonstraing the issue
  • Collect dotcover logs:
  1. Navigate to Help | Diagnostic tools | Choose Trace Scenarios and enable scenarios for DotCover and DotCoverExternalProcess;
  2. Restart Rider;
  3. Reproduce the issue;
  4. Disable Trace scenarios at Help | Diagnostic tools | Choose Trace Scenarios;
  5. Collect the full log bundle via Help | Collect logs. Upload the logs to the Upload Service and share the Upload ID.
     

Regards,

Tom

Thanks Tom! Clearing Rider caches via File | Invalidate caches => Invalidate and restart fixed the problem.  I did not think to try that, though I now recall that Invalidate caches has fixed other Rider glitches for me in the past.

I lost UI connected to running Coverage in 2025.2 too. Following steps from Tom helped.
