Treemap Coverage Visualization

Quickly identify files and directories with poor test coverage using our interactive treemap visualization. Large red blocks highlight areas with significant uncovered code, that might need more attention.

A preview of the treemap visualization showing coverage by file and directory

Our treemap visualization makes it easy to spot coverage problems in your codebase at a glance. Each block represents a file or directory, with:

  • Size based on the amount of uncovered code
  • Color indicating coverage percentage (red = low coverage, yellow = medium coverage, green = high coverage)
  • Interactive navigation to drill down into directories simply by clicking

Large red blocks represent the biggest opportunities to improve your overall coverage. Click on any file to jump directly to its coverage details.
