I should say that I’m fan of regular expressions. Whenever I see the problem, which I can solve with Regex, I felt a burning desire to do it and going to write new test for new regex. Previously I had installed SharpDevelop Studio just for good regular expression tool in it. But now I’m a little wiser, and for each Regex I write a separate test. Now I want to show you little samples of regular expressions and want to show you how to test these samples.
