The tests are split into unit tests and integration tests. To run all tests on your machine run npm test.

npm test                  # run all the tests
npm run test:unit         # run the unit tests

npm run lint

The tests and linter are run when commits are pushed, you can view [results on CI][ci]. They must pass before we merge a pull request.
