…chacli options

To force shutdown of the event loop after test run

From v4.0.0, grunt-mocha-cli use mocha v4.0.0 which no logger use '--no-exit' flag

By default, Mocha will no longer force the process to exit once all tests complete. This means any test code (or code under test) which would normally prevent node from exiting will do so when run in Mocha. Supply the --exit flag to revert to pre-v4.0.0 behavior

Check breaking change: https://github.com/mochajs/mocha/releases/tag/v4.0.0
