{% callout type="caution" title="Can I use component testing?" %} Next component testing with Nx requires Cypress version 10.7.0 and up.

You can migrate with to v10 via the migrate-to-cypress-11 generator.

This generator is for Cypress based component testing.

If you want to test components via Storybook with Cypress, then check out the storybook-configuration generator docs {% /callout %}

This generator is designed to get your Next project up and running with Cypress Component Testing.

nx g @nx/next:cypress-component-configuration --project=my-cool-next-project

Running this generator, adds the required files to the specified project with a preconfigured cypress.config.ts designed for Nx workspaces.

import { defineConfig } from 'cypress';
import { nxComponentTestingPreset } from '@nx/next/plugins/component-testing';

export default defineConfig({
  component: nxComponentTestingPreset(__filename),
});

Here is an example on how to add custom options to the configuration

import { defineConfig } from 'cypress';
import { nxComponentTestingPreset } from '@nx/next/plugins/component-testing';

export default defineConfig({
  component: {
    ...nxComponentTestingPreset(__filename),
    // extra options here
  },
});

nx g @nx/next:cypress-component-project --project=my-cool-next-project

Auto Generating Tests

You can optionally use the --generate-tests flag to generate a test file for each component in your project.

nx g @nx/next:cypress-component-configuration --project=my-cool-next-project --generate-tests

Running Component Tests

A new component-test target will be added to the specified project to run your component tests.

nx g component-test my-cool-next-project

Here is an example of the project configuration that is generated.

{
  "targets" {
    "component-test": {
      "executor": "@nx/cypress:cypress",
      "options": {
        "cypressConfig": "<path-to-project-root>/cypress.config.ts",
        "testingType": "component",
        "skipServe": true
      }
    }
  }
}

Nx also supports Angular component testing.
