Verify a string 2 times in the same test

[xoofx]

Hello!

I have a case with Verify that I'm not sure how to best handle. My unit test is:

• Generating from a data a version textual representation. => We verify that we have the expected output
• Reprocessing the data without changing it in the end
• Generating again a textual representation with the new data => We verify that we have the same output than previously

The code looks like this:

   string textV1 = data.ToString();

   await Verifier.Verify(textv1).UseParameters(name);

   // Reprocess data, but it should not change it
   data.ReprocessWithoutChanges();
   string textV2 = data.ToString();

   // The textV2 is supposed to be equivalent to the textV1, but is generated differently
   await Verifier.Verify(textv2).UseParameters(name).DisableRequireUniquePrefix();

I have to use DisableRequireUniquePrefix() because otherwise Verify is seeing that I'm trying to verify the same file. But in practice, that's what I would like.

The problem with DisableRequireUniquePrefix() is that it doesn't differentiate the context between the 1st Verify and the 2nd, so I don't know which one is failing.

Is there any way to differentiate in the error log these Verify steps on a same text?

In the meantime, I have found a temporary workaround by doing this:

   // ...
   data.ReprocessWithoutChanges();
   string textV2 = data.ToString();

   if (textV1 != textV2)
   {
       TestContext.WriteLine("Error with ReprocessWithoutChanges");
       // The textV2 is supposed to be equivalent to the textV1, but is generated differently
       await Verifier.Verify(textv2).UseParameters(name).DisableRequireUniquePrefix();
   }
