在Rails6中获取或发布ActionCable测试

Question

我正在使用JWT对我的用户进行身份验证。

因此，当用户想要连接到ActionCable服务器时，它会执行以下操作：

• 从REST端点获取JWT：POST/users/sign_in
• 使用这个jwt建立一个ws-to-ActionCable

// Establish connection
ws = new WebSocket("ws://localhost:3000/websocket?token="+jwt)

我想测试这个连接，所以我使用Rails 6中开箱即用的东西：

# test/channels/application_cable/connection_test.rb
require "test_helper"
class ApplicationCable::ConnectionTest < ActionCable::Connection::TestCase
test "connects with jwt" do
post "/users/sign_in", params: { user: {email: "[e-mail]", password: "ok"}}, as: :json
token  = response.headers["Authorization"]
connect params: { token: token }
assert_equal connection.user_id, "1"
end
end

但我有以下错误：

Error:
ApplicationCable::ConnectionTest#test_connects_with_jwt:
NoMethodError: undefined method `post' for #<ApplicationCable::ConnectionTest:0x0000555bbab0ecb0>
test/channels/application_cable/connection_test.rb:6:in `block in <class:ConnectionTest>

我应该做些什么才能对我的控制器执行此post？谢谢

奖金：如果我可以使用路由前缀，即user_session_url而不是"/users/sign_in"，那就更好了！

您可以通过在测试类中包含ActionDispatch::IntegrationTest::Behavior来获取所有的ActionDispatch::IntegrationTest好东西。

我还没有用ActionCable::Connection::TestCase测试过这一点，但我正在把它和我的通道测试一起使用，比如：

require "test_helper"
class FoosChannelTest < ActionCable::Channel::TestCase
include ActionDispatch::IntegrationTest::Behavior
tests FoosChannel
let(:user) { create(:user) }
describe "when a new Foo is created" do
it "broadcasts an event to the user channel" do
post foos_path, params: {
foo: {
name: "Foo1",
}
}, as: :json
assert_broadcasts user, 1
end
end
end

我使用了这个https://relishapp.com/palkan/action-cable-testing/docs(相同的代码可用于请求规范(

RSpec.describe CommentsController do
describe "POST #create" do
expect { post :create, comment: { text: 'Cool!' } }.to
have_broadcasted_to("comments").with(text: 'Cool!')
end
end

不要忘记禁用后台作业(如果作业延迟，请添加Delayed::Worker.delay_jobs = false(
