Windows Phone 7 mocking framework?

Are there any mocking frameworks for Windows Phone 7 or do I need to create fakes manually?

I've not found any on google, and although I found Moq listed on WP7开发者_JAVA百科 resources page, I couldn't get it working.

There are no Mocking frameworks that support WP7 and I suspect there will never be any until WP7 supports Reflection.Emit.

On the .net framework there are many options that exist for the creation of a mocking framework (Profiler API, CodeDem, Refleciton.Emit, et al). The majority of these techniques won't work on Silverlight itself as it's missing quite a lot of the BCL/CLR. All existing Silverlight mocking frameworks use Reflection.Emit. WP7 does not support Reflection.Emit and thus no Silverlight mocking framework will work on WP7.

Because of that reason, I personally test WP7 assemblies on the Silverlight runtime. It's far from optimal (it sucks), but it's the best that can be done under the circumstances.

One could theoretically build a Mocking framework that uses Post-Build MSIL weaving that should work on WP7, but it's yet to be done.

If you'd like WP7 to support Reflection.Emit consider voting on this uservoice issue: WP7 should support Reflection.Emit for Mocking frameworks

EDIT 2/12/2011: Refleciton.Emit is supported on Mango. Hooray! Reflection.Emit based Mocking frameworks should just work.

I'm not aware of any currently available.

This article by David Gadd shows an example of testing on the phone using manually created fake objects and may be a useful resource.

I just got TypeMock Isolator, and it works with Windows Phone 7 (sortof).

You need to create a default Visual Studio Test project, and you will get an error saying that your Windows Phone 7 project can not be referenced, but for some reason the Mocks and Tests work perfectly.

Anyway, I'm really happy with the mocks it is able to create.

Any mocking framework that supports Silverlight 3 should work with Windows Phone 7. You may need to use a previous version of the framework to "dumb it down" to Silverlight 3, though.

Just wanted to notice some information that I found on MSDN:

The mock classes were manually developed as it is not possible to use a mocking framework on the Windows Phone platform. Mocking frameworks require the ability to emit Microsoft intermediate language (MSIL) code, which is not currently possible on the Windows Phone platform
