Running the tests


Go through the setup instructions for JavaScript to install the necessary dependencies.


Install assignment dependencies:

# Using npm
npm install

# Alternatively using yarn

Making the test suite pass

All exercises come with a test suite to help you validate your solution before submitting. You can execute these tests by opening a command prompt in the exercise's directory, and then running:

# Using npm
npm test

# Alternatively using yarn
yarn test

In some test suites all tests but the first have been skipped.

Once you get a test passing, you can enable the next one by changing xtest to test.

Writing custom tests

If you wish to write additional, custom, tests, create a new file custom.spec.js, and submit it with your solution together with the new file:

exercism submit numbers.js custom.spec.js

Submitting your solution

You can submit your solution using the exercism submit enchantments.js command. This command will upload your solution to the Exercism website and print the solution page's URL.

It's possible to submit an incomplete solution which allows you to:

  • See how others have completed the exercise
  • Request help from a mentor
