🚦 Introduce the concepts of TDD and BabySteps

The three laws of TDD

• You are not allowed to write any more of a unit test that is sufficient to fail, and compilation failures are failures
• You are not allowed to write any production code unless it is to make a failing unit test pass
• You are not allowed to write any more production code that is sufficient to pass the one failing unit test

Refactoring and the Rule of Three – baby steps

• The Rule of Three defers duplication minimization until there is enough evidence. Code that does not contain duplication is often referred to as abiding to the DRY (Do not Repeat Yourself) principle.

Three methods of moving forward in TDD

• Fake it
• Obvious implementation
• Triangulation

Detect axes

• The idea is that we stay in one behavior until we are sure that behavior is completed. ​

Naming tests

• Tests should have names that describe a business feature or behavior
