rspecのstubとmockについて

Posted at

モックとスタブの使い分け

モック

「オブジェクトのメソッドがどう呼ばれて何を返すか」というインタフェースも含めたテストのために使う

スタブ

テストをスムーズに行うために「あるオブジェクトのメソッドが呼ばれたら、ある戻り値を返す」ために使う

# object.stub(:is_dummy?).and_return(true)
User.stub(:is_dummy?).and_return(true)


この書き方から

# allow(object).to receive(method).and_return(return value)
allow(User).to receive(:is_dummy?).and_return(true)

に書き換える

こっちのがいいのかな

allow_any_instance_of(Widget).to receive(:name).and_return("Wibble")
expect_any_instance_of(Widget).to receive(:name).and_return("Wobble")
