Summary
In this chapter, we explored the world of testing.
We tried to give you a fairly comprehensive overview of testing, especially unit testing, which is the kind of testing that a developer mostly does. We hope we have succeeded in conveying the message that testing is not something that is perfectly defined and that you can learn from a book. You need to experiment with it a lot before you get comfortable. Of all the efforts a coder must make in terms of study and experimentation, we would say testing is the one that is the most important.
In the next chapter, we're going to explore debugging and profiling, which are techniques that go hand in hand with testing, and are crucial to learn well.
We are aware that we gave you a lot of pointers in this chapter, with no links or directions. This was by choice. As a coder, there won't be a single day at work when you won't have to look something up on a documentation page, in a manual, on a website...
