What do people build with it?

USE CASE 1

Run tests on code that depends on webpack-specific features like custom loaders or module resolution.

USE CASE 2

Use watch mode to automatically re-run only the tests affected by a recent code change.

USE CASE 3

Get test failures that point to your original source code instead of the compiled bundle, thanks to automatic source maps.

USE CASE 4

Switch an existing mocha test suite to work with webpack-bundled code with almost no CLI changes.
