This TYPO3 extension is an example for writing unit and functional tests for extbase/fluid-based extensions for TYPO3 CMS using PHPUnit.

It also is an example for best practices for extbase/fluid.

For information on the different ways to execute the tests, please have a look at the handout to my workshops on test-driven development (TDD).

Running the unit tests from the command line

.Build/bin/phpunit -c .Build/vendor/nimut/testing-framework/res/Configuration/UnitTests.xml Tests/Unit/

Running the tests in PhpStorm

General PHPUnit setup

composer require typo3/cms ^8.7
composer install
git checkout HEAD -- composer.json

File > Settings > Languages & Frameworks > PHP > Test Frameworks

  • (*) Use Composer autoloader
  • Path to script: select .Build/vendor/autoload.php in your project folder

In the Run configurations, edit the PHPUnit configuration and use these settings so this configuration can serve as a template:

  • Directory: use the Tests/Unit directory in your project
  • Use alternative configuration file
  • use .Build/vendor/nimut/testing-framework/res/Configuration/UnitTests.xml in your project folder
  • Add the following environment variables:
    • typo3DatabaseUsername
    • typo3DatabasePassword
    • typo3DatabaseHost
    • typo3DatabaseName

Unit tests configuration

In the Run configurations, copy the PHPUnit configuration and use these settings:

  • Directory: use the Tests/Unit directory in your project

Functional tests configuration

In the Run configurations, copy the PHPUnit configuration and use these settings:

  • Directory: use the Tests/Functional directory in your project
  • Use alternative configuration file
  • use .Build/vendor/nimut/testing-framework/res/Configuration/FunctionalTests.xml

Running the acceptance tests

On the command line

  1. make sure you have Chrome installed on your machine
  2. composer update codeception/codeception (just in case)
  3. download the latest version of ChromeDriver
  4. unzip it
  5. chromedriver --url-base=wd/hub
  6. .Build/vendor/bin/codecept run (in another terminal)

In PhpStorm

  1. make sure the "Codeception Framework" plugin is activated
  2. right-click on Tests/Acceptance/StarterCest.php
  3. Run 'Acceptance (Codeception)'

Creating new extensions with automated tests

For creating new extensions, I recommend taking Helmut Hummel's extension skeleton as a starting point.

About me (Oliver Klee)

I am the maintainer of the PHPUnit TYPO3 extension, which is available in the TYPO3 extension repository (TER).

You can book me for workshops at your company.

I also frequently give workshops at the TYPO3 Developer Days.
