# Coverage Hotspots

**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](/cloud/projects/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.

## Related hotspot views

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.
