## Code coverage
Currently we're aiming for at least 80% test coverage for our code. To ensure your changes meet or exceed this limit, run `npm run js-compile && npm run js-test` and open the file in `js/coverage/lcov-report/index.html` to see the code coverage for each plugin. See more details when you select a plugin and ensure your change is fully covered by unit tests.
### Example tests ### Example tests
```javascript ```js
// Synchronous test // Synchronous test
QUnit.test('should describe the unit being tested', function (assert) { QUnit.test('should describe the unit being tested', function (assert) {
