E2E/Integration testing with Cypress

First, you need to make sure that Cypress is installed and also create the cypress folder in the root of your repository yourself, as you would do normally.

After that, add a new cantara.config.js file in the root of your repository (if not done so already).

Add the following content:

module.exports = {
e2e: {
executeBefore: [
'ctra dev express-api --stage test',
'ctra dev random-image-app --stage test',
portsToWaitFor: [8080, 3000],
testCommand: 'cypress run',

Now, when you execute ctra e2e the following happens:

  • The Express server is started in development mode
  • The random-image React app is also started in development mode
  • Cantara waits for both servers on the ports 8080 and 3000 to be available
  • As soon as the ports are available, cypress run is executed (so the tests in your cypress folder are executed)

As you can see, the commands under executeBefore and the testCommand could have any value, so it's not solely limited to Cypress.
