Coverage Hotspots highlight the files in your project with the worst line coverage on the tracked branch. They’re surfaced on the project’s Overview page under the Coverage tab, and exist to give you a short, actionable list of files to focus on when you’re trying to lift overall coverage.

​
How files are picked

The Coverage Hotspots list contains the top 5 files on the project’s tracked branch with the lowest line coverage percentage, with two filtering rules:
  1. Files with no coverage data are excluded (they show up as “uncovered” but aren’t ranked alongside files with measured coverage).
  2. Directory entries are excluded; only individual files appear.
Each entry shows:
  • The filename (the last segment of the path; hover for the full path).
  • The line coverage percentage for that file.
  • The file’s maintainability grade.
Clicking any entry opens the file’s metrics page, where you can see line-by-line coverage and the open issues affecting the file.

​
When the list is empty

If no coverage data has been uploaded yet for the tracked branch, the list shows a message and a button linking to the project’s coverage setup page so you can wire up uploads. Once a coverage report lands successfully, the list populates on the next page load. The Overview’s lens tabs include two more hotspot lists:
  • Maintainability hotspots — top files by remediation effort.
  • Security hotspots — top files by open security finding count.
All three lists use the same “top 5 files” pattern.
