Run Tests in Travis CI

You can automatically run tests as a part of your build process using TestCafe and Travis CI. There are Linux versions of Chrome and Firefox browsers available for Travis CI builds, so you can run your tests completely in the cloud.

Suppose you have a GitHub project for which you need to automatically run tests in the cloud when the project is modified. To do this, go through the following steps.

• Step 1 - Install TestCafe and create tests
• Step 2 - Enable Travis for your project
• Step 3 - Add the test script to package.json
• Step 4 - Trigger a Travis CI build

Step 1 - Install TestCafe and create tests

Install TestCafe locally in your project and create tests.

Step 2 - Enable Travis for your project

1. Sign in to Travis CI with your GitHub account. Travis CI is synchronized with your repositories from GitHub. You can see them on your profile page.

2. Enable Travis CI for a repository you want to build.

   

   By default, Travic CI runs builds on pushes and pull requests. You can manage this behavior in your repository’s settings.

   

3. Add a .travis.yml configuration file to the root of your project. This file contains parameters and commands that instruct Travis CI how to execute your builds. For more information, see Customizing the Build.

   For Node.js projects that require Firefox and Chrome, the .travis.yml file should have the following content:

   language: node_js
   node_js: "stable"
   
   dist: bionic
   
   before_install:
      - stty cols 80
   
   addons:
      firefox: latest
      chrome: stable
   

   Commit and push this file to your repository.

Step 3 - Add the test script to package.json

To test a project, Travis runs test scripts. For Node.js projects, the default test script is npm test. To tell npm how to run your tests, add the test script to the project’s package.json file. Use the :headless postfix to run browsers in headless mode.

"scripts": {
    "test":  "testcafe chrome:headless,firefox:headless tests/index-test.js"
}

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

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

Step 4 - Trigger a Travis CI build

You can trigger a Travis CI build by pushing commits to your repository or creating a pull request.

To check if the build passed or failed, go to the builds dashboard.
