Summary

Recap

That’s the end of the second chapter. Let’s have a short recap of what was covered and the key takeaways.

You were introduced to the five steps involved in test-driven development. These are as follows:

1. Write the test.
2. Run the test, and see it fail.
3. Write the actual code.
4. Make all tests pass.
5. Refactor the code using the underlying tests as a bedrock to make sure that the refactoring process doesn’t break anything.

Note: The process of writing failing tests, writing code that makes those tests pass, and then refactoring the code to improve it is also called the “Red, Green, Refactor” process.
