Technical details

How it works

The package is a client of the coverage API that was added in Unity 2019.2. For more information, see the coverage API's documentation. The package uses a combination of this API and C# reflection to output the test coverage data in the OpenCover format. Optionally, a third party report generator will then parse the OpenCover data and present the coverage data as a series of html documents.

Requirements

This version of the Code Coverage package is compatible with the following versions of the Unity Editor:

  • 2019.3 and later

3rd party libraries used

Known limitations

Code Coverage includes the following known limitations:

  • Code Coverage currently only supports the OpenCover format.
  • Code Coverage currently only supports code ran in the Editor and not in Standalone/Player.
  • NPath Complexity calculation and Branch Coverage are not implemented at present so they will always appear as zero in the coverage report.
