Chapter 4. Test to Learn
In the previous three chapters we have seen how automated tests can help improve quality of code, guide design and drive development. In this chapter we will use automated tests to learn.

Other types of automated tests can help our understanding of both the language and specific problems. Benchmarks are a valuable tool to measure relative performance, and can guide decisions about how to solve a specific problem.
