Description

Describes the interface for the code coverage data exposed by mono.

Use one of the following methods to enable coverage:
1) Enable Code Coverage in General Preferences
2) Use the Coverage.enabled API
3) Use the Command line argument -enableCodeCoverage in batchmode

Code Coverage is a measure of how much of your code has been executed. It is normally associated with automated tests, but you can gather coverage data in Unity at any time when the Editor is running. It is typically presented as a report that shows the percentage of the code that has been executed. For automated testing the report does not measure the quality of tests, only whether your code is executed by PlayMode and EditMode tests. It is especially useful to check that critical or high risk areas of your code are covered, because they should receive the most rigorous testing.

You can use the Code Coverage package to gather and present code coverage information from your automated tests. Additionally, the Code Coverage package offers a Coverage Recording feature which allows capturing coverage data on demand, for manual testing or when there are no automated tests in the project.

Note that in Unity 2019 and 2020 you can enable Code Coverage in General Preferences. This was removed in Unity 2021; the user interface for managing Code Coverage is now entirely inside the Code Coverage package.
