Testing

To run unit tests for a package:

yarn install
yarn run test
  • We use karma + mocha + chai with Chromium/Firefox to run unit tests both locally and in CI.

We could look into jsdom for testing as an alternative. Last time we looked things were blocked on https://github.com/jsdom/jsdom/pull/2548, but this is now fixed. Testing with a fake browser has the downside of missing bugs in real browsers, so not sure if this is worth it.

  • We use cypress to run end-to-end tests on deployed apps both locally and in CI for Chromium/Firefox/Edge.

  • We use GitLab CI for our CI.
