{% 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](/packages/cypress/generators/migrate-to-cypress-11).
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](/nx-api/react/generators/storybook-configuration). However, this functionality is deprecated, and will be removed on Nx version 18.
{% /callout %}
This generator is designed to get your Next project up and running with Cypress Component Testing.
```shell
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.
```ts {% fileName="cypress.config.ts" %}
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
```ts {% fileName="cypress.config.ts" %}
import { defineConfig } from 'cypress';
import { nxComponentTestingPreset } from '@nx/next/plugins/component-testing';
export default defineConfig({
component: {
...nxComponentTestingPreset(__filename),
// extra options here
},
});
```
```shell
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.
```shell
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.
```shell
nx g component-test my-cool-next-project
```
Here is an example of the project configuration that is generated.
```json {% fileName="project.json" %}
{
"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](/packages/angular/generators/cypress-component-configuration).
