1. Install PHPUnit and Selenium (for FunctionalJavascript tests);

• you can install PHPUnit with Composer:

  composer require phpunit/phpunit

  
  

• NOTE: For Selenium you need to install first npm. Then you can install Selenium with these commands:

  npm install selenium-standalone@latest -g selenium-standalone install

  
  

  • When Selenium is installed run command:

    selenium-standalone start

    
    

• You need to apply this patch contrib-modules-issues-test-running.patch.zip (Our modules depend on many contrib modules and some of these modules have issues (which can be fixed in future)

2. Check PHPUnit configuration for testing:

• Find core/phpunit.xml (if not exist just copy phpunit.xml.dist and rename to phpunit.xml)

• In this file you need to specify these settings:

  <!-- Example SIMPLETEST_BASE_URL value: http://localhost --> <env name="SIMPLETEST_BASE_URL" value=""/> <!-- Example SIMPLETEST_DB value: mysql://username:password@localhost/databasename#table_prefix --> <env name="SIMPLETEST_DB" value=""/> <!-- Example BROWSERTEST_OUTPUT_DIRECTORY value: /path/to/webroot/sites/simpletest/browser_output --> <env name="BROWSERTEST_OUTPUT_DIRECTORY" value=""/>

  
  

• For Selenium running you need to add this line in phpunit.xml:

  <env name="MINK_DRIVER_ARGS_WEBDRIVER" value='["chrome", null, "http://localhost:4444/wd/hub"]'/>

  
  

3. Enable Simpletest module with drush command:

drush en simpletest

4. Run tests:

• Run this test (for example):

  sudo -u www-data -E vendor/bin/phpunit -c core --group opigno_learning_path # Or the same with debug info: sudo -u www-data -E vendor/bin/phpunit -c core --group opigno_learning_path --printer="\Drupal\Tests\Listeners\HtmlOutputPrinter
