If you’re a .NET developer who have been writing tests, this post may encourage you to continue doing so when working with Ruby. If, instead, you have not been writing tests, we must change that! I know I have mentioned this before, but I can’t stress enough how important it is. On my first years as a C# developer I relied too much on the compiler. I had the idea that if the compiler didn’t complain, then my code was correct.
