Question

我正在尝试在rails中的rspec测试中存根XMLRPC :: Client.call。

这是我的方法：

    def xmlrpc_call(location, repeat, func, *args)
     Rails.logger.debug("XML_RPC: calling #{func}(#{args.inspect})")
     timeout = XMLRPC_TIMEOUT ? XMLRPC_TIMEOUT : 90
     begin
      server = XMLRPC::Client.new2(location, nil, timeout)
      result = server.call(func, *args)
     rescue XMLRPC::FaultException => e
      Rails.logger.error "XMLRPC FaultException: #{e.faultCode}, Exception: #{e.faultString}"
      log_abp_error("#{func}: #{e.faultCode} (wrapper, rescue 1, try: #{(repeat ? "1":"2")})")
      @xmlrpc_exception = e
      false
     end
    result
   end#xmlrpc_call

这是我的测试：

  describe "#xmlrpc_call" do
   it 'should return success' do
   stub_request(:post, "http://google.com/RPC2").
           with(:body => "<?xml version=\"1.0\" ?><methodCall> <methodName>CallGoogle</methodName><params><param><value><string>foo</string></value></param><param><value><string>bar</string></value></param></params></methodCall>\n",
                :headers => {'Accept'=>'*/*', 'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3', 'Connection'=>'keep-alive', 'Content-Length'=>'200', 'Content-Type'=>'text/xml; charset=utf-8', 'User-Agent'=>'XMLRPC::Client (Ruby 2.1.1)'}).
           to_return(:status => 200, :body => "success", :headers => {})
   XmlRpcCallHelper.xmlrpc_call("http://google.com", true, "CallGoogle", "foo", "bar")
  end#success
end#xmlrpc_call

我收到了这个错误：

 Failure/Error: XmlRpcCallHelper.xmlrpc_call("http://google.com", true, "CallGoogle", "foo", "bar")
 RuntimeError:
   Missing return value!

如果我在存根中使用空响应体，我会得到：

Failure/Error: XmlRpcCallHelper.xmlrpc_call("http://google.com", true, "CallGoogle", "foo", "bar")
 NoMethodError:
   undefined method `bytesize' for nil:NilClass

此Using webmock to mock XMLRPC client in rspec-rails对我也不起作用。

非常感谢任何帮助。谢谢！

Answer 1

使用此代码创建响应。

before do stub_request(:post, "http://api-test.com/host_add").to_return( { :body => XMLRPC::Create.new.methodResponse(true, { hoge: "test"} ), :status => 200 } ) end是对xml的哈希

该代码对我有用：

    context "success" do
  before do
    stub_request(:post, "http://srv476.offsidebet.com:8080/abp/webApiXmlRpcServlet").
       with(:body => "<?xml version=\"1.0\" ?><methodCall><methodName>func</methodName><params><param><value><string>a</string></value></param><param><value><string>b</string></value></param><param><value><string>c</string></value></param></params></methodCall>\n",
            :headers => {'Accept'=>'*/*', 'Accept-Encoding'=>'gzip;q=1.0,deflate;q=0.6,identity;q=0.3', 'Connection'=>'keep-alive', 'Content-Length'=>'238', 'Content-Type'=>'text/xml; charset=utf-8', 'User-Agent'=>'XMLRPC::Client (Ruby 2.1.1)'}).
       to_return(:status => 200, :body => File.read("#{Rails.root}/spec/fixtures/xml_rpc_call_helper/response_ok.xml"), :headers => {})
  end
  let(:response){ {"wm_description"=>"manual create", "wm_ticket_number"=>"1408171142773", "ABPBuildNumber"=>"436 r${svn.Revision}", "wm_payment_number"=>"41902112", "wm_sim_mode"=>"0", "wm_redirect_url"=>"https://exmaple.com/entrypoint", "WEBAPIVersionNumber"=>"0.57", "wm_purse"=>"12345"} }
  it {XmlRpcCallHelper.xmlrpc_call(XML_RPC_LOCATION, true, 'func', 'a','b','c').should eq(response)}
end#success

夹具：

  <methodResponse>

使用rspec在rails test中对Stub XMLRPC :: Client进行调用
