运行Capybara时如何配置puma？ [英] How can I configure puma when running Capybara?

问题描述

在运行水豚测试时，我想调整彪马的配置。更改.env，.env.test（我使用 dotenv ）或config / puma.rb中的设置没效果。

I'd like to adjust the puma configuration when running Capybara tests. Changing settings in .env, .env.test (I use dotenv), or config/puma.rb has no effect.

在哪里可以更改配置？

Rails 5.1，poltergeist 1.15.0，capybara 2.14 .0，puma 2.8.2

Rails 5.1, poltergeist 1.15.0, capybara 2.14.0, puma 2.8.2

推荐答案

通常使用Capybara，您可以在register_server块中配置服务器。 Capybara提供的：puma服务器定义是

Generally with Capybara you configure the server in a register_server block. The :puma server definition Capybara provides is

Capybara.register_server :puma do |app, port, host|
  require 'rack/handler/puma'
  Rack::Handler::Puma.run(app, Host: host, Port: port, Threads: "0:4")
end

如果您使用的是Rails 5.1系统测试，则在服务器上添加了一层抽象配置已在
ActionDispatch :: SystemTesting :: Server＃register中完成，定义为

If you're using Rails 5.1 system testing it has added a layer of abstraction on top of that with server configuration being done in ActionDispatch::SystemTesting::Server#register which is defined as

def register
  Capybara.register_server :rails_puma do |app, port, host|
    Rack::Handler::Puma.run(app, Port: port, Threads: "0:1")
  end
end

无论哪种方式，您都应该能够覆盖当前服务器注册之一

Either way you should be able to either overwrite one of the current server registrations

Capybara.register_server :rails_puma do |app, port,host|
  Rack::Handler::Puma.run(app, ...custom settings...)
end

或配置自己的

Capybara.register_server :my_custom_puma do |app, port, host|
  Rack::Handler::Puma.run(app, ...custom settings...)
end

Capybara.server = :my_custom_puma
