ruby-on-rails - 使用 RSpec 验证部分参数

Question

我需要对一个参数设置期望值。如何访问从 RSpec 接收到的参数？

这是我想要实现的。

let(:api) { double('API') }

it "should pass :filter in options" do
  api.should_receive(:traverse)
  subject.execute
  args = api.recevied_arguments_for(:traverse) # How to obtain all the arguments?
  args[0].should have_key(:filter)
end

要回答问题，请用评论修复该行。

谢谢。

刚刚想通了。 比我想象的要好得多。

let(:api) { double('API') }
it "should pass :filter in options" do
  api.should_receive(:traverse).with hash_including(:filter)
  # or with the exact value
  #api.should_receive(:traverse).with hash_including(:filter => 'something')
  subject.execute
end
