Development

Running tests

mocha is used for testing.

Start by creating a file options.json in tests/ that looks like:

{
  "shop": "YourDevShop.myshopify.com",
  "appKey": "your app key",
  "appSecret": "your app secret",
}

Run npm test. Your default browser should open a few tabs to run the tests using the provided dev shop.
