如何在Rails服务器上运行Capybara？ [英] How to run Capybara against a Rails server?

问题描述

我有一个使用OAuth2 gem发出HTTP请求的测试：

I have a test that uses OAuth2 gem to make make an HTTP request:

token = client.auth_code.get_token( code, redirect_uri:redirect_uri )

Capybara似乎没有将Rails应用程序作为服务器运行：

Capybara does not seem to be running the Rails app as a server:

Faraday::ConnectionFailed:
   Connection refused - connect(2) for "localhost" port 3000

这里是配置：

Capybara.app_host = "http://localhost:3000"
Capybara.run_server = true
Capybara.server_port = 3000
Capybara.register_driver :rack_test do |app|
  Capybara::RackTest::Driver.new app,
    follow_redirects:false
end

各种文档似乎都建议上述配置将应用程序作为服务器运行，但事实并非如此。

Various docs seem to suggest that the above config will run the app as a server, but it does not seem to be the case.

如何在服务器上运行Capybara，以便服务器响应HTTP请求？

编辑：在Capybara代码中进行挖掘之后，似乎不同的驱动程序具有不同的服务器。与Poltergeist合作。因此，也许Poltergeist不支持运行服务器。

After digging in the Capybara code, it seems that different drivers have different servers. Working with Poltergeist. So perhaps Poltergeist doesn't support running a server.

推荐答案

像往常一样，忽略了一个小细节。

As usual, a small detail was overlooked.

该规范必须标记为：js 。否则，它将使用Rack :: Test并且服务器不会启动。

The spec must be tagged as :js. Otherwise it uses Rack::Test and the server is not started.
