Question

我正在写我的第一个ApprovalTest。我需要理解为什么当我的文件都相同时我会收到以下错误。

move /Y "C:\SampleMvc-master\SampleMvc-master\SampleMvc.Tests\Controllers\GoldenMasterTest.About.received.html" "C:\SampleMvc-master\SampleMvc-master\SampleMvc.Tests\Controllers\GoldenMasterTest.About.approved.html"
move /Y "C:\SampleMvc-master\SampleMvc-master\SampleMvc.Tests\Controllers\GoldenMasterTest.About.received.html" "C:\SampleMvc-master\SampleMvc-master\SampleMvc.Tests\Controllers\GoldenMasterTest.About.approved.html"

Test method SampleMvc.Tests.Controllers.GoldenMasterTest.About threw exception: 
ApprovalTests.Core.Exceptions.ApprovalMismatchException: Failed Approval: Received file C:\SampleMvc-master\SampleMvc-master\SampleMvc.Tests\Controllers\GoldenMasterTest.About.received.html does not match approved file C:\SampleMvc-master\SampleMvc-master\SampleMvc.Tests\Controllers\GoldenMasterTest.About.approved.html.

我的代码是

[TestMethod]
        public void About()
        {

            //AspApprovals.VerifyUrl("http://localhost:50011/Home/About");
            MvcApprovals.VerifyMvcPage(new HomeController().About);

        }

ApprovalTests使用“黄金大师”的验证方式。这意味着你第一次跑步时总会失败。一旦失败，但产生了正确的结果，你将移动文件，然后它将通过并继续通过，直到发生变化。

有多种方法可以创建黄金大师，但通过命令行可以轻松实现，这就是为什么你会看到

move / Y“C：\ SampleMvc-master \ SampleMvc-master \ SampleMvc.Tests \ Controllers \ GoldenMasterTest.About.received.html”“C：\ SampleMvc-master \ SampleMvc-master \ SampleMvc.Tests \ Controllers \ GoldenMasterTest.About.approved.html“

这会从.received文件中创建.approved文件。

您可能还想查看有关记者的视频，这有助于探索创建黄金大师的其他方法并查看生成的结果： Reporter video
