Learning Functional Programming in Go

Testing FP using test-driven development

Let's write some tests to verify each technique (simple recursive, memoized, and channeled) works properly. We'll use TDD to help us design and write better code.

TDD, a software development method where the developer starts with requirements and first writes a simple test that will fail. Then, it writes just enough code to make it pass. It continues this unit testing pattern repeatedly until there are no more reasonable tests that validate the code satisfies the requirements. The concept is to get something working now and perfect it later. After each test, refactoring is performed to implement a little more of the feature requirement.

The same or similar test(s) are performed again as well as introducing ...
