Use Travis to build a Drupal site with Composer, test with Behat, and then deploy to Pantheon.

1.4.6 2015-08-04 22:27 UTC


This project is deprecated; will be replaced with a newer and more comprehensive example Drupal 7 Travis CI Composer project, which will be used to quickly create your own derived project. See the example Drupal 7 Circle CI Composer project, which is more up-to-date, but works with Circle CI rather than Travis.

Original Documentation

This project is designed to be included from the require section of a Drupal site's composer.json file. Doing this allows you to achieve the following things:

  • Specify the Drupal modules, themes and libraries you use in your composer.json file, and build them with Composer.
  • Automatically build components via Travis or Circle CI every commit.
  • Use Behat to run tests on your site from Travis.
  • Automatically deploy your site to your Pantheon dev environment, or some other branch, every time the tests pass.

All of this can be accomplished with only a few light files committed to your repository.


Copy the contents of the examples directory to the root of your project, renaming files as appropriate:

  example.gitignore     -> .gitignore
  example.travis.yml    -> .travis.yml
  example.behat.yml     -> behat.yml
  features              -> features

You will also need a composer.json file for your project. The project example-drupal7-travis-composer can be used as a template to quickly create your own project; for Drupal 8, see drupal-composer/drupal-project.


You must customize the contents of these files to suit the needs of your project. See the detailed instructions below; more information is also available in the comments inside each file.


Do not use the composer.json file included in the pantheon-systems/travis-scripts project; instead, use one from a project mentioned in the section Setup, above.

Set the name and description in your composer.json file to something appropriate for your project.

Customize the require section to contain the modules and themes needed for your project. You might want to try using drush composer-generate to get started. If you want to run your site on Pantheon, then you should keep "pantheon-systems/drops-7" as your main component; otherwise, you may replace this with "drupal/drupal" if you prefer.

The custom installers in the require section of your composer.json file control the way the components in your project are installed. Always keep these items at the top, so that they are available at the very beginning of the installation process. Modules and themes listed before the custom installers might not install correctly.

Travis CI

Set up your project to be tested by Travis CI:

  • Log in to in your web browser
  • Click on the "+" next to "My Repositories"
  • Find the repository you would like to configure to test. Navigate to the right organization, if necessary, and click "sync" if the repository was created recently.
  • Enable the repository by clicking on the checkbox next to it.
  • Push a commit to your repository to start a build.

Next, set up the environment variables used by the push-to-pantheon script.

Define the environment variables that identify your site in the global section of your .travis.yml env. See the comments in the file for instructions, especially for the encrypted environment variables and encrypted private key file. The encrypted items are only necessary if you want to push your site to Pantheon after every successful test run. You will need to set up your repository to be tested by Travis as shown above in order to encrypt your Travis API key.

You also need to set up an ssh key, so that the push-to-pantheon script can commit changes to the Pantheon git repository.

  • Create a public/private ssh key pair. You might want to use a different key than the one you use with GitHub.
  • Add the public ssh key to your Pantheon account.
  • Encrypt your private key for Travis.
    • Name your private key travis-ci-key, and place it at the base of your project (this file is already in the starting .gitignore file).
    • Create your encrypted key with cd travis && travis encrypt-file travis-ci-key.
    • Copy the openssl line output by travis encrypt-file into your .travis.yml file, replacing the openssl line that already exists in the after_success section.
    • Commit the generated travis-ci-key.enc and all changes to your .travis.yml file.

The other parts of the example .travis.yml file should run without modification. Note that the scripts run from the bin directory come from either the scripts directory of this project (which are copied to the bin directory when you require "pantheon-systems/travis-scripts" in your project's composer.json), or from some other component require-dev (e.g. behat).

See the Travis CI documentation for instructions on how to set up GitHub integration, so that your code will be automatically tested on every commit.


This sample is set up to run a single behat test that confirms that the name of the site was set correctly by drush site-install. Note that the first part of the site name is set by the SITE_NAME environment variable that you customize in your .travis.yml file; the second part of the site name is set to Travis Test Site on Travis, and Pantheon Test Site on Pantheon.

See the behat documentation for further instructions on adding more tests to your project.

Local Testing

Once setup is complete, doing local testing is a simple matter of:

$ composer install
$ ./bin/local-test
