Moling System.dll

Question

I need to unit test a method that is using the System.Net.WebClient in the System.dll. I tried to Mole the System.dll, but when I tried to compile the project to add references to the System.dll mole, I got a bunch of errors like the following:

Error 2

Error 3

And finally

Error 28

The command ""C:\Program Files\Microsoft Moles\bin\moles.exe" @C:\DGALibrary\DGALib.IO.Tests\obj\x86\Debug\Moles\moles.args" exited with code -1002. DGALib.IO.Tests

Are we not able to mole system.dll?

Answer 1

try this

<Moles xmlns="http://schemas.microsoft.com/moles/2010/">
  <Assembly Name="System" ExportedTypes="true" ReflectionOnly="true"/>  
</Moles>

Answer 2

I'm new to Pex/Moles so I can't provide you with an answer as to why the errors are occurring. However, so long as the errors aren't for types you actually need to Mole you can resolve your problem by editing the system.moles file to restrict the types to mole to just the ones you care about.
