static class File

[Rayne]

I'm having trouble mocking File.WriteAllBytes. Here's my test code:

var called = false;
var ccr = new Ccr { Pdf = new byte[73], SubmissionId = 3 };

Mock.Replace<string, byte[]>((s, b) => File.WriteAllBytes(s, b)).In<CcrFileWriter>(x => x.WriteToDisk(ccr));
Mock.Arrange(() => File.WriteAllBytes(null, null)).IgnoreArguments().DoInstead(()=> called = true);

var writer = new CcrFileWriter();
writer.WriteToDisk(ccr);
Assert.IsTrue(called);

It's not working. It's not bypassing File.WriteAllBytes and the test fails.
Maybe I'm not understanding how this should work?

OK, so it does work...in my sample solution. But not in the solution I need it to work in. Not sure yet, what's going on.

I figured out what is causing the problem. The reason it's failing is because I'm using class Ccr as a parameter to the method I'm testing and that class is defined in a different assembly. I got the same failure in my sample project when I moved the classes there to a new project.

I don't know how to fix it though. How do I need to set up my test?

I'm using version 2012.3.1016.3 which I installed yesterday via the Control Panel.

Hi Rayne,

Thanks again for contacting us.

I have sent you a sample project in ticket # 571362 that should clarify the issue. In addition, make sure that you have updated all the references before running the test.

 

Kind Regards
