Hello!
​
Are you still interested in learning about testing? If so, here I have an article that discusses the simplest case for unit tests—pure functions:

​
Do you have questions after reading the article? Great, I'm working on follow-up articles and I would love to hear questions my readers have. You can mail me by responding to this message, or set a one-on-one meeting for us at:
