- 20. BDD Benefits • TDDis actually not about testing • TDD is a design methodology • “Test” Driven Development encourages “Test” mindset and delays mastery of TDD • BDD encourages starting from the behavior and the use of • Mock objects

- 25. Mock Objects • MockRoles not Objects • System Under Test & Collaborators • “Mocks aren’t Stubs” (or dummies) • State vs. Behavior Verification • Java tools - jMock, EasyMock, Mockito
- 26. JMock Example SUT sut= new SUT(); // System Under Test Mock mock = new Mock(Collab.class); //setup expectations mock.expects(once()).method(“neededMethod”) .with(eq(1), eq(“String param”)); //exercise sut.testedMethod((Collab) mock.proxy()); //verify mock.verify(); assertEquals(EXPECTED_STATE, sut.state());
- 27. Bad Mocking (thanks PaoliniCarolini & Sudhindra Rao) • Unreadable tests • Replacing Integration Testing • Unnecessary (e.g.Value Object) • Context Confusion • Mock returns Mock • Mock Abuse (better: FakeDB, Dummy, Stub, Fixture)
- 28. Dynamic Languages & Groovy
- 29. Groovy = lesscode
- 30. Other Groovy Features •Fully compatible with Java code • Can use Static Types • Easy to make Domain Specific Language • Dynamic typing, closures, metaprogramming, etc. • Easy XML processing, string & list handling

- 33. Decision vs. Exploration • Discussion is “convergent”. It assumes a single viewpoint must be chosen. • Dialog or Conversation allows for exploration and does not require decision. • Dialog is critical for many Agile processes. • User Research, Retrospectives, Learning
- 34. Dialog Processes • WorldCafé • Open Space Technology • Deep Democracy • Appreciative Inquiry
- 35. Leadership Stage • Coaching •Organizational Development • Change Management • Collaborative vs. “Command & Control” • Leadership & Self-Organizing • “Stepping Up & Stepping Back”
