Running Cypress Tests with Supabase and Remix

The Makerkit SaaS boilerplate comes with a set of predefined tests with the following goals:

1. Verify that the boilerplate application works well
2. Provide instructions for building your own tests

As your application grows, the tests will inevitably need to be updated and maintained. We hope that our tests will be simple to understand and to change when you will need them.

Running the Remix development server

First, we have to run the following command to run Remix with a testing environment (i.e. using .env.test):

npm run dev:test

This command will start a Remix dev server at http://localhost:3000, so it's important to make sure you have no other Remix server running at the same port.

Additionally, we have to start the Supabase local instance:

npm run supabase:start

Running Cypress in development mode

While you build your tests, it can be handy to use a windowed version of the Cypress testing suite, so that you can easily retry the tests without having to re-run the while tests suite.

To do that, run the following command:

npm run cypress

Running All Cypress tests

Whenever you want to run all your tests at once, you can use the following commands:

npm run cypress:headless

This will run all the tests and exit.

Running Cypress in CI mode

Whenever you want to run all your tests in a CI environment, you can use the following commands:

npm test

The command above will:

1. Start the Supabase local instance
2. Start the Remix environment
3. Run the tests in headless mode
4. Exit and close all the processes

As you may have noticed, this is the command to run in your CI environment.

Testing Stripe

Testing Stripe requires one more process to start, i.e. the official Stripe emulator.

The command below will require Docker installed, which is why you can choose to disable it by setting the environment variable ENABLE_STRIPE_TESTING to false from the .env.test environment file:

ENABLE_STRIPE_TESTING=false

If instead, you want to test Stripe Checkout as well, run the command below:

npm run stripe:mock-server

As we've mentioned, this will require Docker running. Of course, we think it's worth it.
