用 Mockery 模拟 Symfony 表单 'query_builder'答案

【问题标题】：Mock Symfony Form 'query_builder' with Mockery用 Mockery 模拟 Symfony 表单 'query_builder'

【问题描述】：

我正在努力在 Symfony 表单测试中模拟 query_builder 选项，我尝试使用 m:on(function () {}) 但无济于事...

这是我想要实现的一个示例：

namespace AppBundle\Form;

use Symfony\Component\Form\AbstractType;

class MyCustomForm extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $userToken = 'this will be a TokenInterface object';

        $builder->add('field1', EntityType::class, [
            'label' => 'My Label',
            'class' => 'AppBundle:MyClass',
            'query_builder' => function (MyClassRepository $repository) use ($userToken) {
                return $repository->setUserToken($userToken)->orderBy('alias.column_1');
        ]);
    }
}

我想要做的是测试 setUserToken 和 orderBy 方法在模拟对象上被调用。

namespace tests\Unit\AppBundle\Form;

class MyCustomFormTest extends \PHPUnit_Framework_TestCase
{
    // Setup test class etc...

    public function testBuildingTheForm()
    {
        $this->builder->shouldReceive('add')
            ->once()
            ->with('field1', EntityType::class, [
                'label'         => 'My Label',
                'class'         => 'AppBundle:MyClass',
                'query_builder' => m::on(function ($closure) use ($userToken) {
                    // Test calls
                    // Test a mock method call with($userToken)

                    return true;
                },
            ]);

        $this->testClass->buildForm($this->builder, []);
    }
}

这是我收到的错误：

1) Tests\Unit\AppBundle\Form\MyCustomFormTest::testBuildingTheForm
Mockery\Exception\NoMatchingExpectationException: No matching handler found for Mockery_0_IteratorAggregate_Symfony_Component_Form_FormBuilderInterface::add("field1", "Symfony\Bridge\Doctrine\Form\Type\EntityType", array('label'=>'My Label','class'=>'AppBundle:MyClass','query_builder'=>'object(Closure)',)). Either the method was unexpected or its arguments matched no expected argument list for this method

你不能像那样嵌入Mockery::on，所以你需要把它提升一个级别，像这样：

public function testBuildingTheForm()
{
    $this->builder->shouldReceive('add')
        ->once()
        ->with('field1', EntityType::class, m::on(function ($options) use ($userToken) {
            $this->assertEquals('My Label', $options['label'];
            $this->assertEquals('AppBundle:MyClass', $options['class'];

            // whatever you need to test with $options['query_builder']

            return true;
        }));

    $this->testClass->buildForm($this->builder, []);
}

感谢 Dave Marshall，我想出了一个解决方案！

测试类：

namespace tests\Unit\AppBundle\Form;

class MyCustomFormTest extends \PHPUnit_Framework_TestCase
{
    // Setup test class etc...

    public function testBuildingTheForm()
    {
        $this->builder->shouldReceive('add')
            ->once()
            ->with('field1', EntityType::class, m::on(function ($options) use ($userToken) {
                $this->assertSame('My Label',          $options['label']);
                $this->assertSame('AppBundle:MyClass', $options['class']);

                $mockRepository = m::mock('AppBundle\Repository\ MyClassRepository');
                $mockRepository->shouldReceive('setUserToken')->with($userToken)->once()->andReturnSelf();
                $mockRepository->shouldReceive('orderBy')->with('alias.column_1', 'ASC')->once()->andReturnSelf();

                $options['query_builder']($mockRepository);

                return true;
            }));

        $this->testClass->buildForm($this->builder, []);
    }
}
