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

Test-Driven Development Small steps Frequent check-ins

Test-Driven Development Deeper than “test first” Design for testability

Test-Driven Development Unit tests as example code Interface before implementation Function drives form

Test-Driven Development Loose coupling Services with clear responsibilities Mock objects
