我正在尝试制作一个将所有请求都匹配fcm.googleapis.com的stub_request。我们的后端应该在创建新帖子或评论时向其用户发送推送通知。我们的测试会触发大量 fcm.googleapis.com 请求，这就是为什么我需要通用匹配器。
编辑：测试失败，因为我已将stub_request添加到spec_helper。失败的测试不是rspec，而是普通的ActionController::TestCase测试。我的坏！:-|
规格/spec_helper.rb
18 RSpec.configure do |config|
19 require_relative "../test/mock_helper"
20 require "webmock/rspec"
21
22 WebMock.disable_net_connect!
23 config.before(:each) do
24 stub_request(:post, "https://fcm.googleapis.com/fcm/send").
25 with(body: /.*/).
26 to_return(status: 200)
27
但是当我运行测试时，看起来 WebMock 并不关心我的stub_request。可能出了什么问题？
运行测试
Error:
PostsControllerTest#test_should_create_post:
WebMock::NetConnectNotAllowedError: Real HTTP connections are disabled.
Unregistered request: POST https://fcm.googleapis.com/fcm/send with body
'{"registration_ids":[null],"notification":
{"title":"Fred Flintstone har skrevet en melding i Bedrock Sportsballteam",
"text":"New post!?"},"data":{"notification":{"avatar":null,"group_id":131900578,
"issued_at":"2018-06-25T13:37:28.746+02:00",
"full_name":"Fred Flintstone","id":700,"post_id":980190963,
"role_id":1}}}' with headers {'Authorization'=>'key=KEY', 'Content-Type'=>'application/json'}
You can stub this request with the following snippet:
stub_request(:post, "https://fcm.googleapis.com/fcm/send").
with(:body => "{"registration_ids":[null],"notification":
{"title":"Fred Flintstone har skrevet en melding i Bedrock Sportsballteam",
"text":"New post!?"},"data":{"notification":
{"avatar":null,"group_id":131900578,
"issued_at":"2018-06-25T13:37:28.746+02:00",
"full_name":"Fred Flintstone","id":700,"post_id":980190963,"role_id":1}}}",
:headers => {'Authorization'=>'key=KEY',
'Content-Type'=>'application/json'}).
to_return(:status => 200, :body => "", :headers => {})
