The aim of the testing framework is to provide a good way to write and run unit and functional tests for multiple versions of the TYPO3 CMS. Currently TYPO3 CMS 9.5 up to 11.5 are tested and supported.

Use Composer to install the testing framework.

composer require --dev nimut/testing-framework

Composer will add the package as a dev requirement to your composer.json and install PHPUnit and vfsStream as its dependencies.

Inherit your test class from \Nimut\TestingFramework\TestCase\UnitTestCase.

To execute the unit tests of your extension run

vendor/bin/phpunit -c vendor/nimut/testing-framework/res/Configuration/UnitTests.xml \
    typo3conf/ext/example_extension/Tests/Unit

For an easy way to test your Fluid ViewHelper you can inherit the test class from \Nimut\TestingFramework\TestCase\ViewHelperBaseTestcase.

You should setup your subject class in your setUp() method of the test class:

/**
 * @var \PHPUnit_Framework_MockObject_MockObject
 */
protected $viewHelper;

protected function setUp()
{
    parent::setUp();
    $this->viewHelper = $this->getMockBuilder(RenderChildrenViewHelper::class)->setMethods(['renderChildren'])->getMock();
    $this->injectDependenciesIntoViewHelper($this->viewHelper);
    $this->viewHelper->initializeArguments();
}

Inherit your test class from \Nimut\TestingFramework\TestCase\FunctionalTestCase.

To execute the functional tests of your extension run

vendor/bin/phpunit -c vendor/nimut/testing-framework/res/Configuration/FunctionalTests.xml \
    typo3conf/ext/example_extension/Tests/Functional

You can add a script section to your composer.json file to symlink your extension to the proper root-dir/web-dir.

"scripts": {
    "post-autoload-dump": [
        "@prepare-extension-test-structure"
    ],
    "prepare-extension-test-structure": [
        "Nimut\\TestingFramework\\Composer\\ExtensionTestEnvironment::prepare"
    ]
}

To be able to test against TYPO3 CMS 8 and later, nimut/testing-framework provides an own database abstraction layer.

In your FunctionalTestCase call $this->getDatabaseConnection() to get an instance of \Nimut\TestingFramework\Database\DatabaseInterface.

Following database functions are built in the nimut/testing-framework database interface:

• select
• selectSingleRow
• selectCount
• insertArray
• lastInsertId
• updateArray
• delete
• getDatabaseInstance

If you need own database requests you can get the proper database instance of the current TYPO3 version by using $this->getDatabaseConnection()->getDatabaseInstance(). You have to check weather this instance is a \TYPO3\CMS\Core\Database\Query\QueryBuilder (TYPO3 CMS 8 and above) or an instance of \TYPO3\CMS\Core\Database\DatabaseConnection (TYPO3 CMS 7).

The nimut/testing-framework ships database fixtures for several TYPO3 CMS core database tables:

• pages
• pages_language_overlay
• sys_file_storage
• sys_language
• tt_content

To use the database fixtures you can trigger an import in your test file

$this->importDataSet('ntf:https://Database/pages.xml');

The nimut/testing-framework ships an own TypoScript file for supporting frontend requests out of the box.

// First import some page records
$this->importDataSet('ntf:https://Database/pages.xml');

// Import tt_content record that should be shown on your home page
$this->importDataSet('ntf:https://Database/tt_content.xml');

// Setup the page with uid 1 and include the TypoScript as sys_template record
$this->setUpFrontendRootPage(1, array('ntf:https://TypoScript/JsonRenderer.ts'));

// Fetch the frontend response
$response = $this->getFrontendResponse(1);

// Assert no error has occured
$this->assertSame('success', $response->getStatus());

// Get the first section from the response
$sections = $response->getResponseSections();
$defaultSection = array_shift($sections);

// Get the section structure
$structure = $defaultSection->getStructure();

// Make assertions for the structure
$this->assertTrue(is_array($structure['pages:1']['__contents']['tt_content:1']));

The returned structure of a frontend request is an array with some information about your page and its children.

[
    // Page for your request
    'pages:1' => [
        'uid' => '1',
        'pid' => '0',
        'sorting' => '0',
        'title' => 'Root',
        // Array with subpages
        '__pages' => [
            'pages:2' => [
                'uid' => '2',
                'pid' => '1',
                'sorting' => '0',
                'title' => 'Dummy 1-2',
            ],
            'pages:5' => [
                'uid' => '5',
                'pid' => '1',
                'sorting' => '0',
                'title' => 'Dummy 1-5',
            ],
        ],
        // Array with content elements
        '__contents' => [
              'tt_content:1' => [
                  'uid' => '1',
                  'pid' => '1',
                  'sorting' => '0',
                  'header' => 'Test content',
                  'sys_language_uid' => '0',
                  'categories' => '0',
              ],
        ],
    ],
]

If you need additional information about a record, you can provide additional TypoScript with the needed configuration.

// Setup the page with uid 1 and include ntf and own TypoScript
$this->setUpFrontendRootPage(
    1,
    array(
        'ntf:https://TypoScript/JsonRenderer.ts',
        'EXT:example_extension/Tests/Functional/Fixtures/TypoScript/Config.ts'
    )
);

Content of the TypoScript file Config.ts

config.watcher.tableFields.tt_content = uid,_ORIG_uid,_LOCALIZED_UID,pid,sorting,sys_language_uid,header,categories,CType,subheader,bodytext
