I have been reading the massive article

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnpag2/html/mtf.asp

posted in the Microsoft web site with the title of "Testing .NET Application Blocks–Version 1.0".

I can not say that I liked it. I consider it useful, I think that will take me some time to fully digest it contents, however, I would say that it could be written in a less bone-dry tone. For example, I should be excited to read the article after reading the introduction, not to consider that it could be appropriate to read it...

In addition, there are tendentious comments :-). For example

"Testing Methodologies" is not an honest report about the different testing methodologies. It is a naked attempt of Agile apologetics. After the authors, Agile has no disadvantage at all! What about scalability for example? The more I know about Agile, the more attractive I find some aspects. However, you should not forget all the strings this methodology has attached: a competent, committed and engaged customer for starters....

In any case, if you have lots of patience, are not sleep deprived and have some time, it is a reading that I recommend.
