Rob Caron has stated that the Guidelines for Test-Driven Development posts on MSDN is erroneous and will be corrected and that Microsoft has no intention of “redefining” TDD.

“We’re aware of the issue and are taking steps to rectify it. An error in a help topic is no different than a coding error – it’s a bug and we’re fixing it. Because of the process involved in publishing product documentation on MSDN, it takes a little bit of time to get updated files in place.“

So far the MSDN article has been rated by over 350 people and has an average rating of 1.13 on a scale from 1 to 9.
