测试将上传文件附加到表单提交与 PhpSpec

Question

我正在尝试测试一个图像导入器，该程序获取文件并提交附加了该图像的表单。测试的那部分似乎是它失败的部分，我不确定如何解决它。

我理解不"嘲笑你不拥有的东西"的概念，但是如果不承认对私有方法的调用，insertImageThroughForm测试不起作用。

我收到以下错误：

75  ! imports image assets
        method call:
          - submit(["file" => ["assetFile" => ["file" => SymfonyComponentHttpFoundationFileUploadedFile:0000000027d380bc00007f8c6cad27ec Object (

            'size' => null
            'error' => 0
        )]]], false)

您正在测试的与其说是单元测试，不如说是集成测试。PhpSpec 不适合集成测试，而仅适用于低单元测试。为什么是集成测试？因为您使用的是真正的文件系统，它是外部服务，也很少有第三方库，如Filesystem和Finder。

您正在尝试模拟Finder但Finder直接在方法中初始化，因此无法模拟。您需要将Finder作为类的依赖项注入。
