Is there a test suite coverage tool for Unity?

In rails projects we use simplecove for code coverage. Is there a way to integrate the Unity with mono coverage or some other toolset?

I’m not sure if this is currently possible outside of a Windows environment (see Wellmann’s comment for info on that.) However, there is an open feature request for Unity to add a test coverage report. Please support this idea by voting on it!

Yes. You can download the Unity Test Tools for free on the asset store. Gamasutra recently ran a nice article on how it works.

You can use DotCover in Windows:

With some tricks you can automate this as well.

You can use the Code Coverage package, available in 2019.3. For more details see the official forum post here https://forum.unity.com/threads/code-coverage-package-preview.777542/
