如何测试ActionCable连接？

Question

如何在RSpec中为ActionCable Connection编写测试？我已经发现documentation和other questions有关测试Channel的信息，但是我很难找到有关测试Connection的信息。

Answer 1

action-cable-testing gem支持测试Connection。这里是文档：https://github.com/palkan/action-cable-testing#rspec-usage

这是文档中给出的RSpec示例：

require "rails_helper"

RSpec.describe ApplicationCable::Connection, type: :channel do
  it "successfully connects" do
    connect "/cable", headers: { "X-USER-ID" => "325" }
    expect(connection.user_id).to eq "325"
  end

  it "rejects connection" do
    expect { connect "/cable" }.to have_rejected_connection
  end
end
