Memphis .NET User Group (MNUG)

Last week I mentioned that I'll be speaking at the NE Arkansas .NET User Group on the 27th. Since then, we've arranged for that presentation to be broadcast via Live Meeting and the Memphis .NET User Group will be joining us live. Someone local will monitor the meeting chat room and relay any questions or comments from the online participants.

.NET Testing Frameworks

Most of my testing experience has been with MSTest, NUnit and Selenium and I feel this is an area I need to explore in more depth, so I thought I'd put the question to my colleagues and readers: What testing frameworks do you prefer and why? Below are a few lists of some .NET oriented frameworks with some notes on what sets each of them apart from others. I welcome comments confirming, challenging or correcting these notes as well as suggestions of others I may have missed.

Unit Testing

• MSUnit - Included with VS, Easy to implement
• NUnit - Most common third party framework
• xUnit - Extensible, lends itself to TDD/BDD
• MbUnit - RowTest for parameterized testing

Acceptance Testing (web)

• Selenium - Relies on CSS ID and class selectors
• WatiN - Works best with IE

Tools

• ReSharper - VS UI enhancements with xUnit integration
• TestDriven.net - VS testing add-in
• dotCover - Code coverage

Mocking

• NMock
• EasyMock.NET
• TypeMock Isolator - Paid, No strings for method names
• Rhino Mocks - Extremely popular
• Moq - Requires .NET 3.5
• NSubstitute - Cleaner with less code needed
• JustMock - Paid
• FakeItEasy - Simplifies fake vs. stub usage
• Microsoft Fakes - Included with VS2012, Previously Moles from MS Research, Includes features other frameworks only offer with paid versions

NE Arkansas .NET User Group

I'm scheduled to speak at the Northeast Arkansas .NET User Group on September 27, 2012. The topic of this talk will be Testing the Untestable with Microsoft Visual Studio 2012 Fakes. I've given this same talk several times at regional conferences and user groups and an overview can be found on my blog, however one great thing about speaking at local groups like this is that the audience helps direct the session and we often end up focusing on areas that are most useful to that particular group.

While anyone is welcome to show up, the group leader has requested that attendees RSVP so they have an idea of how many to expect. See you there!

Testing the Untestable with VS2012 Fakes

One of the new features included with Visual Studio 2012 is the Fakes Framework which offers the ability to detour code at runtime and isolate functionality for true unit testing, regardless of whether the code was written with testing in mind.

I began speaking on Fakes back when it was a beta product from Microsoft Research called Moles. While the core functionality remains the same, Microsoft has streamlined the implementation and now calls the detour mechanism a shim rather than a mole.

If you have attended this or another of my talks at a user group or conference, please take a moment to share your feedback on SpeakerRate.

The PowerPoint is available on SlideShare and below are links to the code demonstrated in the presentation.

Demos
Y2K Checker (simple introduction)
DateTime Audit (avoiding non-deterministic tests)
File Reader (shimming file system access)
Repository (stubbing interfaces)

Resources
Visual Studio 2011
Fakes MSDN Documentation
