The document describes The Kanban Game, which is a collaborative experience used to learn how to use Kanban in a team-building setting. The game includes story cards, chance cards, and a progress tracking sheet. It involves drawing a Kanban board and playing through 3 scenarios with different Kanban configurations over multiple iterations to experiment with Kanban. Retrospectives are held after each game to discuss strategies. The goal is to provide a useful experience for learning and improving Kanban practices.
Functional testing validates that application functions as specified by feeding inputs and examining outputs without considering internal structure. It assesses features against specifications. Good test cases are specific, measurable, achievable, relevant and time-bound. They initially focus on typical happy paths without exceptions. Test cases communicate expectations and allow engineers to verify functionality from the perspective of specification holders.

結合度: TDDが悪く見えるけど微妙
凝集度: TDDの経験が足らない
テストカバレッジ: TDDは非常に良い
56. Additionally…
?TDD damages or breaks an architecture
?TDD people have forgotten the knowledge of testing and
quality (as in Quality Assurance)
?So TDD has little or even negative effects on quality
TDDはアーキテクチャを破壊する
TDDやアジャイルの人は
テストや品質保証の知識が足らない
