Basic

name: End-to-end tests
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      # Install NPM dependencies, cache them correctly
      # and run all Cypress tests
      - name: Cypress run
        uses: cypress-io/github-action@v2

The workflow file .github/workflows/example-basic.yml shows how Cypress runs on GH Actions using Ubuntu (16, 18, or 20), on Windows, and on Mac without additional OS dependencies necessary.

Note: this package assumes that cypress is declared as a development dependency in the package.json file. The cypress NPM module is required to run Cypress via its NPM module API.

Explicit version

Best practice:

Our examples specify the tag of the action to use listing only the major version @v2

- name: Cypress run
  uses: cypress-io/github-action@v2

When using cypress-io/github-action@v2 from your workflow file, you automatically will be using the latest tagged version from this repository. If you want to precisely control the version of this module, use the full tag version, for example:

- name: Cypress run
  uses: cypress-io/github-action@v2.2.7

By using the full version tag, you will avoid accidentally using a newer version of the action.

Browser

Specify the browser name or path with browser parameter

name: E2E on Chrome
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    # let's make sure our tests pass on Chrome browser
    name: E2E on Chrome
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          browser: chrome

Firefox

In order to run Firefox, you need to use non-root user (Firefox security restriction).

name: Firefox
on: push
jobs:
  firefox:
    runs-on: ubuntu-latest
    container:
      image: cypress/browsers:node12.16.1-chrome80-ff73
      options: --user 1001
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          browser: firefox

Note: the magical user id 1001 works because it matches permissions settings on the home folder, see issue #104

Edge

name: Edge
on: push
jobs:
  tests:
    runs-on: windows-latest
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          browser: edge

Note: Microsoft has not released Edge for Linux yet, thus you need to run these tests on Windows or Mac runners with Edge preinstalled. You can use cypress info command to see the browsers installed on the machine.

Headless

Run the browser in headless mode

name: Chrome headless
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          browser: chrome
          headless: true

Docker image

You can run tests in a GH Action in your Docker container.

name: E2E in custom container
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    # Cypress Docker image with Chrome v78
    # and Firefox v70 pre-installed
    container: cypress/browsers:node12.13.0-chrome78-ff70
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          browser: chrome

Env

Specify the env argument with env parameter

name: Cypress tests
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Cypress run with env
        uses: cypress-io/github-action@v2
        with:
          env: host=api.dev.local,port=4222

When passing the environment variables this way, unfortunately due to GitHub Actions syntax, the variables should be listed in a single line, which can be hard to read. As an alternative, you can use the step's env block where every variable can be set on its own line. In this case, you should prefix every variable with CYPRESS_ because such variables are loaded by Cypress automatically. The above code example is equivalent to:

name: Cypress tests
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Cypress run with env
        uses: cypress-io/github-action@v2
        env:
          CYPRESS_host: api.dev.local
          CYPRESS_port: 4222

For more examples, see the workflow example below.

Specs

Specify the spec files to run with spec parameter

name: Cypress tests
on: [push]
jobs:
  cypress-run:
    name: Cypress run
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          spec: cypress/integration/spec1.js

For more information, visit the Cypress command-line docs.

Project

Specify the project to run with project parameter

name: Cypress tests
on: [push]
jobs:
  cypress-run:
    name: Cypress run
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          project: ./some/nested/folder

For more information, visit the Cypress command-line docs.

Record test results on Cypress Dashboard

name: Cypress tests
on: [push]
jobs:
  cypress-run:
    name: Cypress run
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          record: true
        env:
          # pass the Dashboard record key as an environment variable
          CYPRESS_RECORD_KEY: ${{ secrets.CYPRESS_RECORD_KEY }}
          # pass GitHub token to allow accurately detecting a build vs a re-run build
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Tip 1: We recommend using the action with on: [push] instead of on: [pull_request] to get the most accurate information related to the commit on the dashboard. With pull requests, the merge commit is created automatically and might not correspond to a meaningful commit in the repository.

Tip 2: we recommend passing the GITHUB_TOKEN secret (created by the GH Action automatically) as an environment variable. This will allow correctly identifying every build and avoid confusion when re-running a build.

Tip 3: if running on pull_request event, the commit message is "merge SHA into SHA", which is not what you want probably. You can overwrite the commit message sent to the Dashboard by setting an environment variable. See issue 124 for details.

Quiet flag

You can provide quiet flag for cypress run to silence any Cypress specific output from stdout

name: example-quiet
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      # Install NPM dependencies, cache them correctly
      # and run all Cypress tests with `quiet` parameter
      - name: Cypress run
        uses: ./
        with:
          working-directory: examples/quiet
          quiet: true

Tag recordings

You can pass a single or multiple tags when recording a run. For example

name: tags
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-latest
    # let's make sure our "app" works on several versions of Node
    strategy:
      matrix:
        node: [10, 12]
    name: E2E on Node v${{ matrix.node }}
    steps:
      - name: Setup Node
        uses: actions/setup-node@v1
        with:
          node-version: ${{ matrix.node }}
      - run: node -v

      - name: Checkout
        uses: actions/checkout@v1

      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          record: true
          tag: node-${{ matrix.node }}
        env:
          CYPRESS_RECORD_KEY: ${{ secrets.CYPRESS_RECORD_KEY }}
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

The recording will have tags as labels on the run.

You can pass multiple tags using commas like tag: node-10,nightly,staging.

Artifacts

If you don't record the test run on Cypress Dashboard, you can still store generated videos and screenshots as CI artifacts. See cypress-gh-action-example and the workflow example below

name: Artifacts
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    name: Artifacts
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
      # after the test run completes
      # store videos and any screenshots
      # NOTE: screenshots will be generated only if E2E test failed
      # thus we store screenshots only on failures
      # Alternative: create and commit an empty cypress/screenshots folder
      # to always have something to upload
      - uses: actions/upload-artifact@v1
        if: failure()
        with:
          name: cypress-screenshots
          path: cypress/screenshots
      # Test run video was always captured, so this action uses "always()" condition
      - uses: actions/upload-artifact@v1
        if: always()
        with:
          name: cypress-videos
          path: cypress/videos

Config

Specify configuration values with config parameter

name: Cypress tests
on: [push]
jobs:
  cypress-run:
    name: Cypress run
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          config: pageLoadTimeout=100000,baseUrl=http://localhost:3000

Config File

Specify the path to your config file with config-file parameter

name: Cypress tests
on: [push]
jobs:
  cypress-run:
    name: Cypress run
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          config-file: tests/cypress-config.json

Parallel

You can spin multiple containers running in parallel using strategy: matrix argument. Just add more dummy items to the containers: [1, 2, ...] array to spin more free or paid containers. Then use record and parallel parameters to load balance tests

name: Parallel Cypress Tests

on: [push]

jobs:
  test:
    name: Cypress run
    runs-on: ubuntu-16.04
    strategy:
      # when one test fails, DO NOT cancel the other
      # containers, because this will kill Cypress processes
      # leaving the Dashboard hanging ...
      # https://github.com/cypress-io/github-action/issues/48
      fail-fast: false
      matrix:
        # run 3 copies of the current job in parallel
        containers: [1, 2, 3]
    steps:
      - name: Checkout
        uses: actions/checkout@v1

      # because of "record" and "parallel" parameters
      # these containers will load balance all found tests among themselves
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          record: true
          parallel: true
          group: 'Actions example'
        env:
          # pass the Dashboard record key as an environment variable
          CYPRESS_RECORD_KEY: ${{ secrets.CYPRESS_RECORD_KEY }}
          # Recommended: pass the GitHub token lets this action correctly
          # determine the unique run id necessary to re-run the checks
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Warning ⚠️: Cypress actions use GITHUB_TOKEN to get the correct branch and the number of jobs run, making it possible to re-run without the need of pushing an empty commit. If you don't want to use the GITHUB_TOKEN you can still run your tests without problem with the only note that Cypress Dashboard API connects parallel jobs into a single logical run using GitHub commit SHA plus workflow name. If you attempt to re-run GitHub checks, the Dashboard thinks the run has already ended. In order to truly rerun parallel jobs, push an empty commit with git commit --allow-empty -m "re-run checks" && git push. As another work around you can generate and cache a custom build id, read Adding a unique build number to GitHub Actions

Build app

You can run a build step before starting tests

name: Build
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          build: npm run build

Start server

If your tests run against a local server, use start parameter, the server will run in the background and will shut down after tests complete

name: With server
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          start: npm start

Note: sometimes on Windows you need to run a different start command. You can use start-windows parameter for this

name: With server
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          # Linux and MacOS
          start: npm start
          # Takes precedences on Windows
          start-windows: npm run start:windows:server

Note: GitHub cleans up the running server processes automatically. This action does not stop them.

Start multiple servers

You can start multiple server processes. For example, if you have an API to start using npm run api and the web server to start using npm run web you can put those commands in start using comma separation.

name: With servers
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-18.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          start: npm run api, npm run web

Wait-on

If you are starting a local server and it takes a while to start, you can add a parameter wait-on and pass url to wait for the server to respond.

name: After server responds
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          start: npm start
          # quote the url to be safe against YML parsing surprises
          wait-on: 'http://localhost:8080'

By default, wait-on will retry for 60 seconds. You can pass a custom timeout in seconds using wait-on-timeout.

- uses: cypress-io/github-action@v2
  with:
    start: npm start
    wait-on: 'http://localhost:8080/status'
    # wait for 2 minutes for the server to respond
    wait-on-timeout: 120

See also

You can wait for multiple URLs to respond by separating urls with a comma

- uses: cypress-io/github-action@v2
  with:
    # API runs on port 3050
    # Web server runs on port 8080
    start: npm run api, npm run web
    # wait for all services to respond
    wait-on: 'http://localhost:3050, http://localhost:8080'

The action will wait for the first url to respond, then will check the second url, and so on.

You can even use your own command (usually by using npm, yarn, npx) to wait for the server to respond. For example, if you want to use wait-on utility to ping the server and run the Cypress tests after the server responds:

- uses: cypress-io/github-action@v2
  with:
    start: npm start
    wait-on: 'npx wait-on --timeout 5000 http://localhost:3000'

See example-wait-on.yml workflow file.

If this action times out waiting for the server to respond, please see Debugging section in this README file.

Custom install command

If you want to overwrite the install command

- uses: cypress-io/github-action@v2
  with:
    install-command: yarn --frozen-lockfile --silent

See example-install-command.yml workflow file.

Command prefix

You can prefix the default test command using the command-prefix option. This is useful for example when running Percy, which requires the test command to be wrapped with percy exec --.

name: Visual
on: [push]
jobs:
  e2e:
    runs-on: ubuntu-16.04
    steps:
      - name: Checkout
        uses: actions/checkout@v1
      - name: Cypress run
        uses: cypress-io/github-action@v2
        with:
          start: npm start
          # quote the url to be safe against YML parsing surprises
          wait-on: 'http://localhost:8080'
          # the entire command will automatically be prefixed with "npm"
          # and we need the second "npm" to execute "cypress run ..." command line
          command-prefix: 'percy exec -- npx'

See live example angular-pizza-creator.

Custom test command

You can overwrite the Cypress run command with your own

steps:
  - name: Checkout 🛎
    uses: actions/checkout@v1

  - name: Custom tests 🧪
    uses: cypress-io/github-action@v1
    with:
      command: npm run e2e:ci

See .github/workflows/example-custom-command.yml file.

Custom build id

You can overwrite ci-build-id used to link separate machines running tests into a single parallel run.

name: Parallel
on: [push]
jobs:
  test:
    runs-on: ubuntu-16.04
    strategy:
      matrix:
        # run 3 copies of the current job in parallel
        containers: [1, 2, 3]
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          record: true
          parallel: true
          group: 'Actions example'
          ci-build-id: '${{ github.sha }}-${{ github.workflow }}-${{ github.event_name }}'
        env:
          # pass the Dashboard record key as an environment variable
          CYPRESS_RECORD_KEY: ${{ secrets.CYPRESS_RECORD_KEY }}
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Tip: see GitHub Actions environment variables and expression syntax.

Working directory

In a monorepo, the end-to-end test might be placed in a different sub-folder from the application itself, like this

repo/
  app/
  e2e/
    cypress
    cypress.json
  package.json

You can specify the e2e working directory when running Cypress tests using working-directory parameter

on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          start: npm start
          working-directory: e2e

See cypress-gh-action-monorepo for a running example

Subfolders

Sometimes Cypress and end-to-end tests have their own package.json file in a subfolder, like

root/
  e2e/
    (code for installing and running Cypress tests)
    package.json
    package-lock.json
    cypress.json
    cypress

  (code for running the "app" with "npm start")
  package.json
  yarn.lock

In that case you can combine this action with bahmutov/npm-install action to install dependencies separately.

name: E2E
on: push
jobs:
  test:
    runs-on: ubuntu-16.04
    steps:
      - uses: actions/checkout@master
      - name: Install root dependencies
        uses: bahmutov/npm-install@v1

      - name: Start server in the background
        run: npm start &

      # Cypress has its own package.json in folder "e2e"
      - name: Install Cypress and run tests
        uses: cypress-io/github-action@v2
        with:
          working-directory: e2e

See cypress-gh-action-subfolders for example.

Yarn workspaces

This action should discover Yarn workspace correctly. For example, see folder examples/start-and-yarn-workspaces and workflow file example-start-and-yarn-workspaces.yml

name: example-start-and-yarn-workspaces
on: [push]
jobs:
  single:
    # the example has Yarn workspace in its "root" folder
    # examples/start-and-yarn-workspaces
    # and tests in a subfolder like "workspace-1"
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2
        with:
          working-directory: examples/start-and-yarn-workspaces/workspace-1
          build: yarn run build
          start: yarn start
          wait-on: 'http://localhost:5000'

Custom cache key

Sometimes the default cache key does not work. For example, if you cannot share the Node modules across Node versions due to native extensions. In that case pass your own cache-key parameter.

name: End-to-end tests
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-16.04
    # let's make sure our "app" works on several versions of Node
    strategy:
      matrix:
        node: [10, 12]
    name: E2E on Node v${{ matrix.node }}
    steps:
      - name: Setup Node
        uses: actions/setup-node@v1
        with:
          node-version: ${{ matrix.node }}
      - name: Checkout
        uses: actions/checkout@v1
      # run Cypress tests and record them under the same run
      # associated with commit SHA and just give a different group name
      - name: Cypress run
        uses: cypress-io/github-action@v2

          record: true

Node versions

You can run your tests across multiple Node versions.

name: Node versions
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node: [10, 12]
    name: E2E on Node v${{ matrix.node }}
    steps:
      - uses: actions/setup-node@v1
        with:
          node-version: ${{ matrix.node }}
      - uses: actions/checkout@v1
      - uses: cypress-io/github-action@v2

Note: because this action uses npm ci and npx commands, it requires at least Node 8.12 that includes the version of NPM with those commands.

Split install and tests

Sometimes you may want to run additional commands between installation and tests. To enable this use the install and runTests parameters.

name: E2E
on: push
jobs:
  test:
    runs-on: ubuntu-16.04
    steps:
      - uses: actions/checkout@master
      - name: Install dependencies
        uses: cypress-io/github-action@v2
        with:
          # just perform install
          runTests: false
      - run: yarn lint
      - name: Run e2e tests
        uses: cypress-io/github-action@v2
        with:
          # we have already installed all dependencies above
          install: false
          # Cypress tests and config file are in "e2e" folder
          working-directory: e2e

See cypress-gh-action-monorepo for working example.

Custom install

Finally, you might not need this GH Action at all. For example, if you want to split the NPM dependencies installation from the Cypress binary installation, then it makes no sense to use this action. Instead you can install and cache Cypress yourself. See cypress-gh-action-split-install for working example.

Install Cypress only

If the project has many dependencies, but you want to install just Cypress you can combine this action with actions/cache and npm i cypress commands yourself.

- uses: actions/checkout@v2
- uses: actions/cache@v2
  with:
    path: |
      ~/.cache/Cypress
      node_modules
    key: my-cache-${{ runner.os }}-${{ hashFiles('package-lock.json') }}
- run: npm i cypress
- uses: cypress-io/github-action@v2
  with:
    install: false

See .github/workflows/example-install-only.yml file.

More examples

Name	Description
cypress-gh-action-example	uses Yarn, and runs in parallel on several versions of Node, also different browsers
cypress-gh-action-monorepo	splits install and running tests commands, runs Cypress from sub-folder
cypress-gh-action-subfolders	separate folder for Cypress dependencies
cypress-gh-action-split-install	only install NPM dependencies, then install and cache Cypress binary yourself
cypress-gh-action-vue-example	project was scaffolded using Vue CLI
gh-action-and-gh-integration	records to the dashboard and has Cypress GH Integration app installed

Notes

Installation

This action installs local dependencies using lock files. If yarn.lock file is found, the install uses yarn --frozen-lockfile command. Otherwise it expects to find package-lock.json and install using npm ci command.

This action uses several production dependencies. The minimum Node version required to run this action depends on the minimum Node required by the dependencies.

Debugging

You can see verbose messages from GitHub Actions by setting the following secrets (from Debugging Actions Guide)

ACTIONS_RUNNER_DEBUG: true
ACTIONS_STEP_DEBUG: true

The ACTIONS_RUNNER_DEBUG will show generic Actions messages, while ACTIONS_STEP_DEBUG will enable the core.debug(...) messages from this actions.

Logs from the test runner

The above ACTIONS_STEP_DEBUG setting enables the debug logs from the action itself. To see the Cypress debug logs add an environment variable to the action:

- name: Cypress tests with debug logs
  uses: cypress-io/github-action@v2
  env:
    DEBUG: 'cypress:*'

Debugging waiting for URL to respond

If you have a problem with wait-on not working, you can check the src/ping.js logic from the local machine.

• clone this repository to the local machine
• install dependencies with npm install
• start your server
• from another terminal call the ping yourself to validate the server is responding:

$ node src/ping-cli.js <url>

For example

$ node src/ping.js https://example.cypress.io
pinging url https://example.cypress.io for 30 seconds
::debug::pinging https://example.cypress.io has finished ok

Extras

Outputs

This GH Action sets an output dashboardUrl if the run was recorded on Cypress Dashboard, see action.yml. To use this output:

- name: Cypress tests
  uses: cypress-io/github-action@v2
  # let's give this action an ID so we can refer
  # to its output values later
  id: cypress
  # Continue the build in case of an error, as we need to set the
  # commit status in the next step, both in case of success and failure
  continue-on-error: true
  with:
    record: true
  env:
    CYPRESS_RECORD_KEY: ${{ secrets.RECORDING_KEY }}
- name: Print Dashboard URL
  run: |
    echo Cypress finished with: ${{ steps.cypress.outcome }}
    echo See results at ${{ steps.cypress.outputs.dashboardUrl }}

Docker image

If your repository does not have package.json or yarn.json (maybe it contains a static site and does not need any dependencies), you can run Cypress tests using cypress/included:... Cypress Docker images. In that case you don't even need this GH Action, instead use the Docker container and write cypress run command like this example from cypress-gh-action-included

name: included
on: [push]
jobs:
  cypress-run:
    runs-on: ubuntu-latest
    # Docker image with Cypress pre-installed
    # https://github.com/cypress-io/cypress-docker-images/tree/master/included
    container: cypress/included:3.8.3
    steps:
      - uses: actions/checkout@v1
      - run: cypress run

Migration guide

v1 to v2

This is noted as a breaking change ... but you should not see any changes. We have changed how we run Cypress (from using the command line to using the NPM module API), which is a big change. But hopefully our examples are complete and we did not break anyone's code.
