Test-Driven Python Development

Summary

Congratulations! You've completed one cycle of TDD. As you can see, each cycle is very quick. Some cycles, like the one we've just gone through, can be completed in a few seconds. Other cycles might involve a fair amount of cleanup and can take quite a long time. Each cycle will implement a small test, a small bit of functionality to pass the test, and then some cleanup to make the code of high quality.

In this chapter, we looked at what TDD is, how it is different from other forms of unit and integration testing, and wrote our first test.

At this point, our implementation is still very small and very simple. You might be wondering if it is worth all this hype just to write and implement four lines of very simple code. In the next few chapters, ...
