ソフトウェアテスト技法練習帳 ~知識を経験に変える40問~

#①チワワ用の温度計の問題

寒いと表示:24度以下
快適と表示:24度~26度以下
暑いと表示:26度以上

##自分の答え
境界値
・寒い=24.0度と23.9度
・暑い=25.9度と26.0度

有効同値
・快適=25.5度

快適の境界値は暑いと寒いで担保出来る認識

#②キッチンスケールの問題

0~2000gまで1g単位で測れる
それ以上・マイナスだとエラーが表示される

##元々の勘違い
何故かマイナスを小数点と勘違いしていた
 ⇒何でや:thinking:

##自分の答え
境界値
☆2000gと2001g
☆0gと-1g(最初は勘違いして0.1gと書いた)

有効同値
☆0g以下=-50g(最初は勘違いして0.5gと書いた)
☆0~2000g=1000g
☆2001g以上=2050g
