Use the Code Coverage preview package with the Test Runner to gather and present test coverage information. When you run your tests with code coverage enabled, you can see exactly which lines of your code are executed, in addition to whether the tests have passed or failed. For more details see Using Code Coverage with Test Runner. Code Coverage window Once a test run has completed, the Code Coverage package will generate an HTML coverage report showing which lines of your code are covered by tests. Code Coverage currently supports EditMode and PlayMode tests. It also allows you to track the code coverage changes through time. HTML report If you don't have any tests, don't worry! The Code Coverage package offers a Coverage Recording feature which allows capturing coverage data on demand. The Code Coverage package is available as a preview package via the Package Manager for Unity 2019.3 and above. See Installing Code Coverage.
