Coverage Tool Window

View | Tool Windows | Coverage

When you run Jest, Karma, and Mocha tests with coverage, the tool window displays coverage measurement results.

The tool window also opens when you run a client-side application in the special Code Coverage mode to find unused JavaScript, TypeScript, and CSS code. In this mode, the tool window shows how much of code in every file and folder was used.
