Cypress Angular Schematic

🔖 Official Angular Schematic and Builder for the Angular CLI.
This project is maintained by the Cypress Team.

Add this schematic to quickly get up and running with Cypress in your Angular project.

---

What does this schematic do?

Once added to your project, it will:

✅ Install Cypress

✅ Add npm scripts for running Cypress e2e tests in run mode and open mode

✅ Scaffold base Cypress files and directories

✅ Provide the ability to add new e2e and component specs easily using ng-generate

✅ Optional: prompt you to add or update the default ng e2e command to use Cypress for e2e tests.

✅ Optional: prompt you to add a ng ct command to use Cypress component testing.

Requirements

• Angular 13+

Usage ⏯

Adding E2E and Component Testing

To install the schematic via prompts:

ng add @cypress/schematic

To install the schematic via cli arguments (installs both e2e and component testing):

ng add @cypress/schematic --e2e --component

To run Cypress in open mode within your project:

ng run {project-name}:cypress-open

To run Cypress headlessly via run mode within your project:

ng run {project-name}:cypress-run

If you have chosen to add or update the ng e2e command, you can also run Cypress in open mode using this:

ng e2e

If you have chosen to add Cypress component testing, you can run component tests in open mode using this:

ng run {project-name}:ct

Generating New Cypress Spec Files

To generate a new e2e spec file:

ng generate @cypress/schematic:spec 

or (without cli prompt)

ng generate @cypress/schematic:spec {name}

To generate a new component spec file:

ng generate @cypress/schematic:spec --component

or (without cli prompt)

ng generate @cypress/schematic:spec {component name} --component

To generate a new component spec file in a specific folder:

ng generate @cypress/schematic:spec {component name} --component --path {path relative to project root}

To generate new component spec files alongside all component files in a project:

ng generate @cypress/schematic:specs-ct

Builder Options 🛠

Running the builder with a specific browser

Before running Cypress in open mode, ensure that you have started your application server using ng serve.

"cypress-open": {
  "builder": "@cypress/schematic:cypress",
  "options": {
    "watch": true,
    "headless": false,
    "browser": "chrome"
  },
  "configurations": {
    "production": {
      "devServerTarget": "{project-name}:serve:production"
    }
  }
}

Read our docs to learn more about launching browsers with Cypress.

Recording test results to the Cypress Dashboard

We recommend setting your Cypress Dashboard recording key as an environment variable and NOT as a builder option when running it in CI.

"cypress-run": {
  "builder": "@cypress/schematic:cypress",
  "options": {
    "devServerTarget": "{project-name}:serve",
    "record": true,
    "key": "your-cypress-dashboard-recording-key"
  },
  "configurations": {
    "production": {
      "devServerTarget": "{project-name}:production"
    }
  }
}

Read our docs to learn more about recording test results to the Cypress Dashboard.

Specifying a custom config file

It may be useful to have different Cypress configuration files per environment (ie. development, staging, production).

"cypress-run": {
  "builder": "@cypress/schematic:cypress",
  "options": {
    "devServerTarget": "{project-name}:serve",
    "configFile": "cypress.production.json"
  },
  "configurations": {
    "production": {
      "devServerTarget": "{project-name}:production"
    }
  }
}

Read our docs to learn more about all the configuration options Cypress offers.

Running Cypress in parallel mode within CI

"cypress-run": {
  "builder": "@cypress/schematic:cypress",
  "options": {
    "devServerTarget": "{project-name}:serve",
    "parallel": true,
    "record": true,
    "key": "your-cypress-dashboard-recording-key"
  },
  "configurations": {
    "production": {
      "devServerTarget": "{project-name}:production"
    }
  }
}

Specifying a custom reporter and options

You may want to specify a custom reporter. Cypress works with any reporters built for Mocha: built-in, third-party, or custom. In addition to specifying reporters, you can specify reporter options. These differ based on the reporter, and you should refer to its documentation for supported options.

"cypress-run": {
  "builder": "@cypress/schematic:cypress",
  "options": {
    "devServerTarget": "{project-name}:serve",
    "reporter": "junit",
    "reporterOptions": {
      "mochaFile": "results/my-test-output.xml",
      "toConsole": true
    }
  },
  "configurations": {
    "production": {
      "devServerTarget": "{project-name}:production"
    }
  }
}

Read our docs to learn more about working with reporters.

Running the builder with a different baseUrl

You can specify a baseUrl that is different than the one in cypress.json. There are two ways to do this.

1. Add baseUrl to configurations like the following:

"cypress-open": {
  "builder": "@cypress/schematic:cypress",
  "options": {
    "devServerTarget": "{project-name}:serve",
    "watch": true,
    "headless": false
  },
  "configurations": {
    "production": {
      "devServerTarget": "{project-name}:serve:production"
    },
    "local-dev": {
      "devServerTarget": "{project-name}:serve:development",
      "baseUrl": "http://localhost:4002"
    },
    "another-env": {
      "devServerTarget": "{project-name}:serve:development",
      "baseUrl": "http://localhost:4004"
    }
  }
}

1. Add custom options to devServerTarget in angular.json:

"options": {
  "host": "localhost",
  "port": 4200
},

In order to prevent the application from building, add the following to the end of your command:

--dev-server-target=''

Generator Options

Specify Testing Type

The default generated spec is E2E. In order to generate a component test you can run:

ng generate @cypress/schematic:spec --name=button -t component

-t is an alias for testing-type. It accepts e2e or component as arguments. If you are using the CLI tool, a prompt will appear asking which spec type you want to generate.

Specify Filename (bypassing CLI prompt)

In order to bypass the prompt asking for your spec name add a --name= flag like this:

ng generate @cypress/schematic:spec --name=login

This will create a new spec file named login.cy.ts in the default Cypress folder location.

Specify Project

Add a --project= flag to specify the project:

ng generate @cypress/schematic:spec --name=login --project=sandbox

Specify Path

Add a --path= flag to specify the project:

ng generate @cypress/schematic:spec --name=login --path=src/app/tests

This will create a spec file in your specific location, creating folders as needed. By default, new specs are created in either cypress/e2e for E2E specs or cypress/ct for component specs.

Generate Tests for All Components

You can scaffold component test specs alongside all your components in the default project by using:

ng generate @cypress/schematic:specs-ct -g

This will identify files ending in component.ts. It will then create spec files alongside them - if they don't exist.

If you would like to specify a project, you can use the command:

ng generate @cypress/schematic:specs-ct -g -p {project-name}
