Railsアプリで次のテストを試みていました:
test "markup need for store.js.coffee is in place" do
get :index
assert_select '.store .entry > img', 3
assert_select '.entry input[type=submit]', 3
end
テストはすべて問題ありません。失敗やエラーはありませんが、HTML で assert_selects が何を探しているのか理解できません。
私は自分自身をより良い方法で説明しようとします:要素assert_select '.entry input[type=submit]', 3
内で入力タイプ=送信の正確な3つのフィールドを探していますか? .entry
最初の asser_select が探しているものは何ですか?
これは assert_selects が機能する HTML です
