如何在magento 2 phpunit测试中进行依赖注入

use Magento\Framework\TestFramework\Unit\TestCase;

class MyTest extends TestCase
{
    protected function setUp(): void
    {
        parent::setUp();
        // 设置测试环境
        $this->objectManager = new \Magento\Framework\TestFramework\Unit\Helper\ObjectManager($this);
    }

    public function testMyFunctionality()
    {
        // 创建被测试类的Mock对象
        $myClassMock = $this->getMockBuilder(MyClass::class)
            ->disableOriginalConstructor()
            ->getMock();

        // 设置依赖注入
        $dependencyMock = $this->getMockBuilder(MyDependency::class)
            ->disableOriginalConstructor()
            ->getMock();

        $myClassMock->expects($this->once())
            ->method('setDependency')
            ->with($dependencyMock);

        // 执行被测试类的方法
        $myClassMock->myMethod();
    }
}
