npm Scripts

  • npm test - Lint the library and tests, then run the unit tests
  • npm run lint - Lint the source and unit tests
  • npm run watch - Continuously run the unit tests as you make changes to the source
and test files themselves
  • npm run test-browser - Build the library for use with the browser spec runner.
Changes to the source will cause the runner to automatically refresh.
  • npm run build - Lint then build the library
  • npm run coverage - Generate a coverage report

Browser Tests

The browser spec runner can be opened in a browser to run your tests. For it to work, you must first run npm run test-browser. This will set up a watch task that will automatically refresh the tests when your scripts, or the tests, change. The spec runner file is located at test/runner.html: open it in your browser to run tests.
