RhinoMocks AAA Syntax
- by Bill Campbell
Hi,
I've spent a good part of the day trying to figure out why a simple RhinoMocks test doesn't return the value I'm setting in the return. I'm sure that I'm just missing something really simple but I can't figure it out. Here's my test:
[TestMethod]
public void CopyvRAFiles_ShouldCallCopyvRAFiles_ShouldReturnTrue2()
{
FileInfo fi = new FileInfo(@"c:\Myprogram.txt");
FileInfo[] myFileInfo = new FileInfo[2];
myFileInfo[0] = fi;
myFileInfo[1] = fi;
var mockSystemIO = MockRepository.GenerateMock<ISystemIO>();
mockSystemIO.Stub(x => x.GetFilesForCopy("c:")).Return(myFileInfo);
mockSystemIO.Expect(y => y.FileCopyDateCheck(@"c:\Myprogram.txt", @"c:\Myprogram.txt")).Return("Test");
CopyFiles copy = new CopyFiles(mockSystemIO);
List<string> retValue = copy.CopyvRAFiles("c:", "c:", new AdminWindowViewModel(vRASharedData));
mockSystemIO.VerifyAllExpectations();
}
I have an interface for my SystemIO class I'm passing in a mock for that to my CopyFiles class. I'm setting an expectation on my FileCopyDatCheck method and saying that it should Return("Test"). When I step through the code, it returns a null insteaed. Any ideas what I'm missing here?
Here's my CopyFiles class Method:
public List<string> CopyvRAFiles(string currentDirectoryPath, string destPath, AdminWindowViewModel adminWindowViewModel)
{
string fileCopied;
List<string> filesCopied = new List<string>();
try
{
sysIO.CreateDirectoryIfNotExist(destPath);
FileInfo[] files = sysIO.GetFilesForCopy(currentDirectoryPath);
if (files != null)
{
foreach (FileInfo file in files)
{
fileCopied = sysIO.FileCopyDateCheck(file.FullName, destPath + file.Name);
filesCopied.Add(fileCopied);
}
}
//adminWindowViewModel.CheckFilesThatRequireSystemUpdate(filesCopied);
return filesCopied;
}
catch (Exception ex)
{
ExceptionPolicy.HandleException(ex, "vRAClientPolicy");
Console.WriteLine("{0} Exception caught.", ex);
ShowErrorMessageDialog(ex);
return null;
}
}
I would think that "fileCopied" would have the Return value set by the Expect. The GetFilesForCopy returns the two files in myFileInfo. Please Help. :)
thanks in advance!
