Here are some commands useful with the lovely jest.
The setup, enable the jest command in the console:
npm install -g jest-cli
Run a single test with detailed output:
jest <path to the test>/<test name>.spec.js --verbose
Run tests without cache:
jest --nocache
Run tests matching a certain name and show detailed output:
jest -t '<name of the test, as specified in its definition>' --verbose
Important note: done need be used as a parameter, only of async is needed inside the test. If used, do remember to call done() at the end of the function or wherever it is needed.
