Implementing the step definitions

The final piece of the puzzle is the Given, When, and Then functions for matching feature steps with their implementations.

Checking your work as you go along

In this section we will speed through the definition, but make sure you verify each step is working by running Cucumber (with the npx @cucumber/cucumber command) after you’ve implemented each function.

Let’s do it!

1. Create another new directory, features/support, and create a file named features/support/steps.mjs, which starts with the following imports:

   import {
     Given,
     When,
     Then
   } from '@cucumber/cucumber';

2. Then implement the first Given step from our feature file. This one calls into the API using the this.request.post function from Playwright. Note the use of failOnStatusCode, which makes sure that Cucumber fails the test if we don’t get a 200 OK response back:

   Given(
