Using Regular Expressions in Unit Testing?

If there's ever been the perfect case for unit testing, it's got b reglar expressions. If you're looking to get a start on your brown field project and you want to start adding tests, start with some regular expressions. And then you can modify those guyes without being too afraid,. You can put it in all those weird edge cases that you worked around. Do you feel you like em? A, they're ok. I mean, i don't hate them. But i have definitely seen cases where myself, or some one else adds a to do, and then later, myself or someone comes along and does what’s in to be done. Thas amazing.
