測試ViewHelper時，Typo3 v8 UnitTest中未配置數據庫連接默認值

Question

我從Typo3 v7遷移到v8。 我也進行了一些測試，經過一些調整，這些測試仍然可以正常工作。 但是，一項測試仍然失敗。

如果在ViewHelper中正確處理了$this->templateVariableContainer->get('settings')中提供的值，則我有一個UnitTest來測試ViewHelper。

我的測試文件：

namespace SomeVendor\Extension\Tests\Unit\ViewHelper;

use Nimut\TestingFramework\TestCase\ViewHelperBaseTestcase;
use SomeVendor\Extension\ViewHelpers\ContactFormViewHelper;
use TYPO3\CMS\Fluid\Core\ViewHelper\TemplateVariableContainer;


class ContactFormTest extends ViewHelperBaseTestcase {

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

    protected function setUp() {

        parent::setUp();

        $mock = $this->getMockBuilder(ContactFormViewHelper::class);
        $mock->setMethods(['renderChildren']);

        $this->viewHelper = $mock->getMock();
        $this->injectDependenciesIntoViewHelper($this->viewHelper);
        $this->viewHelper->initializeArguments();
    }

    /**
     * @test
     */
    public function testExcludes() {

        $renderingMock = $this->getMockBuilder(\TYPO3\CMS\Fluid\Core\Rendering\RenderingContext::class);

        $templateVariableContainerMock = $this->getMockBuilder(TemplateVariableContainer::class);
        $templateVariableContainerMock
            ->getMock()
            ->method('get')
            ->withAnyParameters()
            ->willReturn([
                'exclude' => ['foo', 'bar']
                ]
            ]);

        $renderingMock
            ->getMock()
            ->method('getTemplateVariableContainer')
            ->willReturn($templateVariableContainerMock);

        $this->viewHelper->setRenderingContext($renderingMock);

        // foo, bar should be excluded in ViewHelper
        // and the array should only contain ['foz', 'baz']
        $resultsCleaned = [
            'foz', 'baz'
        ];

        $this->assertEquals($resultsCleaned, $this->viewHelper->render();
    }

}

經過測試的ViewHelper：

namespace SomeVendor\Extension\ViewHelpers;


class ContactFormViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper {

    const VALID_FIELDS = [
        'foo',
        'bar',
        'foz',
        'baz'
    ];


    /**
     *
     * @return array
     */
    public function render() {

        $retval = [];

        // get settings defined in TS Setup
        // comma separated, eg: foo,bar
        $settings = $this->templateVariableContainer->get('settings');

        if (isset($settings['excludes']) ) {
            $settings = preg_split('/,/', $settings['excludes']);

            if (is_array($settings) === false) {
                $settings = [];
            }

        } else {
            $settings = [];
        }


        // include exclude magic here
        // resulting array $retval contains only values which are NOT excluded

        return $retval;
    }
}

我的測試運行調用如下：

/var/www/html/vendor/bin/phpunit -c /var/www/html/vendor/nimut/testing-framework/res/Configuration/UnitTests.xml /var/www/html/typo3_app/typo3conf/ext/extension/Tests/Unit/ViewHelper/ContactFormTest.php

該測試始終失敗，並出現以下錯誤：

RuntimeException: The requested database connection named "Default" has not been configured.

為什么這里甚至需要數據庫連接？ 因為緩存？ 它在Typo3 v7中起作用。

我的環境：

• PHP 7.1.15
• 錯別字3：8.7.18
• Nimut測試框架：4.0
• PHPUnit：6.5.11

Answer 1

TYPO3版本8.1中的數據庫配置結構已更改

在Breaking（中斷）處有關於此重大更改的更改日志：＃75454-LocalConfiguration DB配置結構已更改

Answer 2

原來，我的遷移過程尚未完全與Typo3 v8兼容。 由於不贊成使用 getTemplateVariableContainer方法， getTemplateVariableContainer這可能是未初始化數據庫連接的根本原因。

我更新了我的測試文件，如下所示，使用此配置，所有測試均為綠色：

namespace SomeVendor\Extension\Tests\Unit\ViewHelper;

use Nimut\TestingFramework\TestCase\ViewHelperBaseTestcase;
use SomeVendor\Extension\ViewHelpers\ContactFormViewHelper;
// use TYPO3\CMS\Fluid\Core\Variables\CmsVariableProvider instead of TYPO3\CMS\Fluid\Core\ViewHelper\TemplateVariableContainer;
use TYPO3\CMS\Fluid\Core\Variables\CmsVariableProvider;


class ContactFormTest extends ViewHelperBaseTestcase {

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

    protected function setUp() {

        parent::setUp();

        $mock = $this->getMockBuilder(ContactFormViewHelper::class);
        $mock->setMethods(['renderChildren']);

        $this->viewHelper = $mock->getMock();
        $this->injectDependenciesIntoViewHelper($this->viewHelper);
        $this->viewHelper->initializeArguments();
    }

    /**
     * @test
     */
    public function testExcludes() {
        // completly remove the setting of the templateVariableContainer through the renderingContext and set it directly through the setVariableProvider, don't forget to call injectDependenciesIntoViewHelper($this->viewHelper) afterwards

        $CMSvariableContainer = $this->getMockBuilder(CmsVariableProvider::class);
        $CMSvariableContainerMock = $CMSvariableContainer->getMock();
        $CMSvariableContainerMock
            ->method('get')
            ->withAnyParameters()
            ->willReturn([
                'exclude' => ['foo', 'bar']
            ]);

        $this->renderingContext->setVariableProvider($CMSvariableContainerMock);
        $this->injectDependenciesIntoViewHelper($this->viewHelper);

        // foo, bar should be excluded in ViewHelper
        // and the array should only contain ['foz', 'baz']
        $resultsCleaned = [
            'foz', 'baz'
        ];

        $this->assertEquals($resultsCleaned, $this->viewHelper->render();
    }

}
