Symfony2 : How to test Configuration nodes values and index

Question

在 Symfony2 中，使用此类设置，我如何测试每个节点是否在 Configuration 中定义？类，并且它们的值已正确配置。

测试类

# My\Bundle\DependencyInjection\Configuration.php

类 Configuration 实现 ConfigurationInterface
{
/**
* {@inheritDoc}
*/
公共(public)函数 getConfigTreeBuilder()
{
$treeBuilder = 新 TreeBuilder();
$treeBuilder->root('my_bundle')
-> child ()
->scalarNode("scalar")->defaultValue("defaultValue")->end()
->arrayNode("arrayNode")
-> child ()
->scalarNode("val1")->defaultValue("defaultValue1")->end()
->scalarNode("val2")->defaultValue("defaultValue2")->end()
->结束()
->结束()
->结束()
;

返回$treeBuilder；
}
}

以下是我想做的断言，在我的单元测试中:

我试图以数组的形式访问节点，但它似乎不起作用。还有 TreeBuilder似乎没有给我们以数组形式获取配置的可能性，除非它们是由捆绑扩展加载的。

测试

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

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

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

//如何访问树生成器的节点？
$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, "测试节点的默认值");
$this->assertEquals("defaultValue", $val1Node, "测试节点的默认值");
$this->assertEquals("defaultValue", $val2Node, "测试节点的默认值");

我发现了一个可以基于 JMSSecurityBundle 工作的解决方案.

我没有测试配置，而是测试了将顺便增加配置覆盖率的扩展。这样，我可以断言设置了默认配置。

例如，这个 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');
    }
}

可能是这样的测试:

#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;
    }
}
