RSpec 是否有可能期望在两个表中发生变化? [英] Is it possible for RSpec to expect change in two tables?

问题描述

RSpec 期望改变:

RSpec expect change:

it "should increment the count" do
  expect{Foo.bar}.to change{Counter.count}.by 1
end

有没有办法期待两个表的变化?

Is there a way to expect change in two tables?

expect{Foo.bar}.to change{Counter.count}.by 1 
and change{AnotherCounter.count}.by 1 

推荐答案

这应该是两个测试.RSpec 最佳实践要求每个测试一个断言.

describe "#bar" do
  subject { lambda { Foo.bar } }

  it { should change { Counter.count }.by 1 }
  it { should change { AnotherCounter.count }.by 1 }
end
