Selenium 2 Tests - Write tests using Selenium 2 with Dusk support

Selenium 2 Tests banner


So you want to write tests in OctoberCMS using Selenium 2?

Using the Ui2TestCase class from this plugin this should be much easier. What is more you do not have to download Selenium bin, since it is included in the package.


System requirements

  1. Java 8 installed in default location of your platform (for example /usr/bin/java for Linux)
  2. The driver of the browser you want to use for tests (for example ChromeDriver)

Note for Linux users

Installing Chromium from your package manager should install ChromeDriver for you

Note for Mac users

You probably will have to link newer version of Java to your default path as described here


  1. You can use three methods to install the plugin:
  2. from OctoberCMS Marketplace,
  3. clone the code from GitHub into /plugins/initbiz/selenium2tests directory or
  4. install using Composer composer require --dev initbiz/oc-selenium2tests-plugin
  5. Add "laravel/dusk": "^2.0" to your require-dev section in composer.json file
  6. Go to /plugins/initbiz/selenium2tests
  7. Copy selenium.php.example to selenium.php and configure your environment

You can also create selenium.php file in your root directory, which will be read when the one in plugin’s directory does not exist

Testing OctoberCMS basics

It is a good practice not to use the same DB for testing and developing purposes.

In order to configure a different database for testing purposes create directory testing in config directory and copy database.php to the newly-created directory. Then change the default connection as you wish.

After that, if you use APP_ENV=testing in your .env file, configuration from the testing directory will be used.

Writing tests in Selenium 2

There are example tests in tests/example directory that use Ui2TestCase class.

Running tests

First of all, you have to run the Selenium 2 standalone server which is included in the package. In order to start Selenium 2 server go to <project_root>/plugins/initbiz/selenium2tests and run java -jar selenium.jar.

You are ready to run tests using PHPUnit from OctoberCMS’s vendor/bin/phpunit.

You can keep test files wherever you want, but .gitignore of the plugin will exclude all files from /tests except those in /tests/examples.

Browser options (like headless mode)

If you want to for example run browser in headless mode, you can add that line to your selenium.php file:

define('TEST_SELENIUM_BROWSER_OPTIONS', ['--headless']);
