AAA or Arrange, Act, and Assert:
Arrange: you need to organize the data needed to execute that piece of code (input);
Act: here you will execute the code being tested (exercise the behaviour);
Assert: after executing the code, you will check if the result (output) is the same as you were expecting.
Three step test cycle:
1. Write a failing - test shouuld fail
2. Write a feature and run it through the test - test should pass by the end of this step
3. Refactor the Code - make it look nice
