Running Tests

It's easy to run the test suite locally, and highly recommended if you're using Chupacabra.js on a platform we aren't automatically testing for.

npm test

SauceLabs Credentials

We've setup our tests to automatically detect whether or not you have our saucelabs credentials installed in your environment (process.env.SAUCE_USERNAME).

If our saucelabs credentials are not installed, the tests are setup to automatically detect all browsers you have installed on your local system, then use them to run the tests.

Obtaining Our SauceLabs Credentials

If you'd like to develop Chupacabra.js using SauceLabs, you need only create a new entry in our issue tracker asking for our SauceLabs credentials.

We'll send over all credentials specific to this project so that you can perform comprehensive cross-platform tests.
