Run Tests in Bitbucket Pipelines

You can run TestCafe tests as a part of your build process on Bitbucket Pipelines CI.

You can set up your Bitbucket project to automatically run tests in the cloud when the project is modified:

Note

TestCafe includes an example that shows how to run tests in Chrome with Bitbucket Pipelines CI.

Step 1 - Install TestCafe and Create Tests

Install TestCafe locally in your project and create tests.

Step 2 - Enable Bitbucket Pipelines for Your Project

To enable Bitbucket Pipelines for your project, create a bitbucket-pipelines.yml file in the project’s root folder.

Bitbucket Pipelines CI allows you to use Docker containers with pre-configured testing environments, including Chrome and Firefox. TestCafe also provides a Docker image you can use to run tests. However, if you already have a Docker image prepared, you can install TestCafe on this image before testing.

For more information about how to get started with Pipelines, see the Atlassian Bitbucket support page.

Option 1 - Use TestCafe Docker Image

Specify the testcafe/testcafe image name in the bitbucket-pipelines.yml file‘s image field. Then, configure a pipeline that installs the project’s dependencies and triggers a custom TestCafe launcher when you push commits and create pull requests.

image: testcafe/testcafe
pipelines:
  pull-requests:
    '**':
      - step:
          script:
            - npm ci
            - /opt/testcafe/docker/testcafe-docker.sh 'firefox:headless,chromium --no-sandbox --disable-dev-shm-usage' tests/**/*

  branches:
    master:
      - step:
          script:
            - npm ci
            - /opt/testcafe/docker/testcafe-docker.sh 'firefox:headless,chromium --no-sandbox --disable-dev-shm-usage' tests/**/*

The custom launcher script /opt/testcafe/docker/testcafe-docker.sh prepares the environment to run a browser and starts TestCafe. Its arguments are standard TestCafe command line parameters.

Note

The --no-sandbox flag is required to run Chrome/Chromium in an unprivileged container. --disable-dev-shm-usage prevents the /dev/shm storage overflow.

Commit and push this file to your repository.

Option 2 - Install TestCafe on a Docker Image

Use the image field in the bitbucket-pipelines.yml file to specify a Docker image with Node.js and browsers installed. Then, configure a pipeline that installs the project’s dependencies and runs tests when you push commits and create pull requests.

# Replace '10.14' with the latest Node.js LTS version
# available on Docker Hub
image: circleci/node:10.14-browsers
pipelines:
  pull-requests:
    '**':
      - step:
          script:
            - npm ci
            - npm test

  branches:
    master:
      - step:
          script:
            - npm ci
            - npm test

To specify how npm should run TestCafe, add the test script to the project’s package.json file and execute the testcafe command in this script.

The following example shows a command that runs tests in Chromium in headless mode:

"scripts": {
    "test":  "testcafe 'chromium:headless --no-sandbox --disable-dev-shm-usage --disable-setuid-sandbox' tests/index-test.js"
}

Note

The --no-sandbox flag is required to run Chrome/Chromium in an unprivileged container. --disable-dev-shm-usage prevents the /dev/shm storage overflow. --disable-setuid-sandbox allows Chromium to run from the root account. It is required for this CircleCI image because it runs all commands with root rights.

For more information on how to configure a test run with the testcafe command, see Command Line Interface.

Commit the changes and push them to your repository.

Tip: Start a Custom Web Server

If you need to start a custom Web server to host your application, use the --app TestCafe option followed by a command that starts this server. TestCafe executes this command before tests are launched. After tests finish, TestCafe stops the server.

"scripts": {
  "test":  "testcafe firefox tests/index-test.js --app \"node server.js\""
}

Step 3 - Trigger a Bitbucket Pipelines CI Build

Bitbucket Pipelines CI is now configured to trigger the build when you push commits to your repository or create a pull request.

To check if the build has passed or failed, open your project’s page and go to the Pipelines status page.

Important

If the build fails with the Unable to establish one or more of the specified browser connections error, refer to this troubleshooting guide.
