Test-Driven Development See also: http://www.agiledata.org/essays/tdd.html Fail Pass Pass Add test Make small change Commit changes

Test-Driven Development Fail Pass Add test Fix bug Commit changes

Test-Driven Development Fail Pass Pass Pass Add test Make small change Refactor Code Commit changes Commit changes

Small steps
Frequent check-ins

Deeper than “test first”
Design for testability

Unit tests as example code
Interface before implementation
Function drives form

Loose coupling
Services with clear responsibilities
Mock objects
