Question

在Symfony2中，使用此类设置，如何测试Configuration类中定义的每个节点，以及它们的值是否已正确配置。

要测试的课程

# My\Bundle\DependencyInjection\Configuration.php

class Configuration implements ConfigurationInterface
{
    /**
     * {@inheritDoc}
     */
    public function getConfigTreeBuilder()
    {
        $treeBuilder = new TreeBuilder();
        $treeBuilder->root('my_bundle')
            ->children()
                ->scalarNode("scalar")->defaultValue("defaultValue")->end()
                ->arrayNode("arrayNode")
                    ->children()
                        ->scalarNode("val1")->defaultValue("defaultValue1")->end()
                        ->scalarNode("val2")->defaultValue("defaultValue2")->end()
                    ->end()
                ->end()
            ->end()
        ;

        return $treeBuilder;
    }
}

以下是我想要做的断言，在我的单元测试中：

我尝试将节点作为数组访问，但它似乎不起作用。此外，TreeBuilder似乎没有让我们将配置作为数组获取，除非它们由bundle扩展加载。

测试

# My\Bundle\Tests\DependencyInjection\ConfigurationTest.php

$configuration = $this->getConfiguration();
$treeBuilder   = $configuration->getConfigTreeBuilder();

$this->assertInstanceOf("Symfony\Component\Config\Definition\Builder\TreeBuilder", $treeBuilder);

// How to access the treebuilder's nodes ?
$rootNode   = $treeBuilder["my_bundle"];
$scalarNode = $treeBuilder["scalar"];
$arrayNode  = $treeBuilder["arrayNode"];
$val1Node   = $arrayNode["val1"];
$val2Node   = $arrayNode["val2"];

$this->assertInstanceOf("Symfony\...\ArrayNodeDefinition", $rootNode);
$this->assertEquals("defaultValue", $scalarNode, "Test the default value of the node");
$this->assertEquals("defaultValue", $val1Node, "Test the default value of the node");
$this->assertEquals("defaultValue", $val2Node, "Test the default value of the node");

我找到了一个可以基于JMSSecurityBundle工作的解决方案。

不是测试配置，而是测试扩展，这将为配置增加覆盖范围。这样，我可以断言已设置默认配置。

例如，这是Extension。

#My\Bundle\DependencyInjection\MyBundleExtension
class MyBundleExtension extends Extension
{
    /**
     * {@inheritDoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config        = $this->processConfiguration($configuration, $configs);

        $container->setParameter("crak_landing_frontend.scalar", $config["scalar"]);
        $container->setParameter("crak_landing_frontend.array_node", $config["array_node"]);

        $loader = new Loader\XmlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('services.xml');
    }
}

可以进行如下测试：

#My\Bundle\Tests\DependencyInjection\MyBundleExtensionTest
class MyBundleExtensionTest extends \PHPUnit_Framework_TestCase
{
    /**
     * @var MyBundleExtension
     */
    private $extension;

    /**
     * Root name of the configuration
     *
     * @var string
     */
    private $root;

    public function setUp()
    {
        parent::setUp();

        $this->extension = $this->getExtension();
        $this->root      = "my_bundle";
    }

    public function testGetConfigWithDefaultValues()
    {
        $this->extension->load(array(), $container = $this->getContainer());

        $this->assertTrue($container->hasParameter($this->root . ".scalar"));
        $this->assertEquals("defaultValue", $container->getParameter($this->root . ".scalar"));

        $expected = array(
            "val1" => "defaultValue1",
            "val2" => "defaultValue2",
        );
        $this->assertTrue($container->hasParameter($this->root . ".array_node"));
        $this->assertEquals($expected, $container->getParameter($this->root . ".array_node"));
    }

    public function testGetConfigWithOverrideValues()
    {
        $configs = array(
            "scalar"     => "scalarValue",
            "array_node" => array(
                "val1" => "array_value_1",
                "val2" => "array_value_2",
            ),
        );

        $this->extension->load(array($configs), $container = $this->getContainer());

        $this->assertTrue($container->hasParameter($this->root . ".scalar"));
        $this->assertEquals("scalarValue", $container->getParameter($this->root . ".scalar"));

        $expected = array(
            "val1" => "array_value_1",
            "val2" => "array_value_2",
        );
        $this->assertTrue($container->hasParameter($this->root . ".array_node"));
        $this->assertEquals($expected, $container->getParameter($this->root . ".array_node"));
    }

    /**
     * @return MyBundleExtension
     */
    protected function getExtension()
    {
        return new MyBundleExtension();
    }

    /**
     * @return ContainerBuilder
     */
    private function getContainer()
    {
        $container = new ContainerBuilder();

        return $container;
    }
}

要测试您的配置隔离，您可以执行以下操作：

use Foo\YourBundle\DependencyInjection\Configuration;
use PHPUnit\Framework\TestCase;

class ConfigurationTest extends TestCase
{
    /**
     * @dataProvider dataTestConfiguration
     *
     * @param mixed $inputConfig
     * @param mixed $expectedConfig
     */
    public function testConfiguration($inputConfig, $expectedConfig)
    {
        $configuration = new Configuration();

        $node = $configuration->getConfigTreeBuilder()
            ->buildTree();
        $normalizedConfig = $node->normalize($inputConfig);
        $finalizedConfig = $node->finalize($normalizedConfig);

        $this->assertEquals($expectedConfig, $finalizedConfig);
    }

    public function dataTestConfiguration()
    {
        return [
            'test configuration'   => [
                ['input'],
                ['expected_config']
            ],
            // ...
        ];
    }
}
