Craftsmanship is the state of knowing how to do something well and is the outcome of lots of experience

Disciplines

• Test-Driven Development: Small cycles and tests come first
• Refactoring: The act of manipulating an unstructured code into code with a better structure—without affecting behavior
• Simple Design: 4 rules
• Collaborative Programming: Pair programming, Mob programming, code-review
• Acceptance test: Behaviors are encoded into tests. If those tests pass, the system behaves as specified.

Test-Driven Development

laws of TDD

• Write no production code until you have first written a test that fails due to the lack of that production code.
• Write no more of a test than is sufficient to fail or fail to compile. Resolve the failure by writing some production code.
• Write no more production code that will resolve the currently failing test. Once the test passes, write more test code.

Benefits:

• No debugging-foo
• Low-level documentation
• Better design
• More Fun
• Lose the fear of change
• Guarantee deployment
