RSpec 1つのexpectで複数のchangeを検証する

Last updated at Posted at 2019-10-29

表題通り1つのexpectに対して複数のchangeを検証したい

it '複数のchangeを見るぞ' do
  expect { subject }.to change { x }.by(1).
                    and change { y }.by(2)
end

長くなるし見づらいのであまり使いたくない…

it '複数のchangeの結果だけ見るパターン' do
  # x, y が 1, 2になることだけ確認するbyは使え無さそう
  expect { subject }.to change { [x, y] }.to [1 ,2]
end

RSpec3.1からの機能らしい
