A lot of people have been asking me lately, what is the cost of testing, so I decided, that I will try to measure it, to dispel the myth that testing takes twice as long.
For the last two weeks I have been keeping track of the amount of time I spent writing tests versus the time writing production code. The number surprised even me, but after I thought about it, it makes a lot of sense. The magic number is about 10% of time spent on writing tests. Now before, you think I am nuts, let me back it up with some real numbers from a personal project I have been working on.
