On demand coverage recording
With Coverage Recording you can capture coverage data on demand and generate an HTML report which shows which lines of your code run while recording. It supports capturing in EditMode as well as in PlayMode, and you can switch between the two.
To start recording coverage data, select the Start Recording button. While recording, use the editor as usual, for example to enter Play Mode. To stop recording coverage data, select the Stop Recording button. If Auto Generate Report is checked, then an HTML report is generated and a file viewer window opens. It contains the coverage results and the report. Otherwise, select the Generate from Last button to generate the report. The results are based on the assemblies specified in Included Assemblies.
You can also control Coverage Recording via the CodeCoverage ScriptingAPI.
Make sure Code Coverage is enabled (see Enable Code Coverage).
Open the Code Coverage window (go to Window > General > Code Coverage).
Select the Assembly Definitions you would like to see the coverage for. In this example we selected
Assembly-CSharp-Editor. By default, Unity compiles almost all project scripts into the
Assembly-CSharp.dllmanaged assembly and all editor scripts into the
Select the Start Recording button.
Continue using the Editor as normal, for example enter PlayMode to test your application or run some manual testing.
When you have finished your testing and have collected enough coverage data, select the Stop Recording button.
A file viewer window will open up containing the coverage report. Note that to generate the report automatically after you stop recording you should have Auto Generate Report checked in the Code Coverage window. Alternatively, you can select the Generate from Last button.
This opens the HTML coverage report.
