是的,我知道最好使用webmock,但是我想知道如何在RSpec中模拟此方法:

def method_to_test
  url = URI.parse uri
  req = Net::HTTP::Post.new url.path
  res = Net::HTTP.start(url.host, url.port) do |http|
    http.request req, foo: 1
  end
  res
end

这是 RSpec:
let( :uri ) { 'http://example.com' }

specify 'HTTP call' do
  http = mock :http
  Net::HTTP.stub!(:start).and_yield http
  http.should_receive(:request).with(Net::HTTP::Post.new(uri), foo: 1)
    .and_return 202
  method_to_test.should == 202
end

测试失败,因为 with 似乎试图匹配 NET::HTTP::Post 对象:
RSpec::Mocks::MockExpectationError: (Mock :http).request(#<Net::HTTP::Post POST>, {:foo=>"1"})
expected: 1 time
received: 0 times

Mock :http received :request with unexpected arguments
     expected: (#<Net::HTTP::Post POST>, {:foo=>"1"})
          got: (#<Net::HTTP::Post POST>, {:foo=>"1"})

如何正确搭配?

最佳答案

如果你不关心确切的实例,你可以使用 an_instance_of 方法:

http.should_receive(:request).with(an_instance_of(Net::HTTP::Post), foo: 1)
.and_return 202
