Capybara/Poltergeist 无法连接到服务器（连接被拒绝 + GET '/identify'）
Capybara/Poltergeist failed to reach server (Connection refused + GET '/identify')
更新
test.log 显示服务器正在响应我们的测试并呈现页面。- 闹鬼失败
Capybara::Poltergeist::StatusFailError: Request to 'http://127.0.0.1:50712/computers' failed to reach server, check DNS and/or server status - Timed out with no open resource requests。
Poltergeist 无法连接到服务器。
我尝试了许多变体，包括：
- 更长的超时时间（最多 300 秒）。
- 正在将 Capybara.app_host 设置为 www.example.com、localhost 或 127.0.0.1。
- 删除 phantomjs_options.
- 正在从
static_controller.rb 中删除 force_ssl if: :ssl_configured?。
- 渲染
users/sign_in 没有布局以消除外部 javascript。
- 将测试更改为调用
new_user_session_path、new_user_session_url 和 /users/sign_in。
- 运行
RAILS_ENV=test rake assets:precompile 在 运行 测试之前（手动）。
当我运行rails s -e test时，我可以打开URL127.0.0.1:3000/users/sign_in.
这是我遇到的错误：

它显示试图访问“http://127.0.0.1/users/sign_in”的事实告诉您某处存在配置错误，因为那里应该有一个端口号（水豚从未 运行 对其进行测试端口 80）。
首先，您设置了 Capybara.server_port = 3000。您是否需要这样做而不是让 Capybara 分配一个随机的空闲端口？如果你确实需要修复它，3000 是一个糟糕的选择，因为这会阻止你在测试 运行.
时让你的开发实例 运行ning
其次，您设置了 Capybara.app_host。你真的需要设置这个吗？当您要针对外部站点进行测试，或者如果您有特殊的 IP 要求时，通常会使用它。如果你真的需要设置 app_host 你可能还需要设置 Capybara.always_include_port = true
所以两个解决方案
取消设置 app_host 和 server_port，让 Capybara 管理它们
将您的固定服务器端口更改为 3000 以外的端口并添加 Capybara.always_include_port = true
此外，您可能还想阅读 https://github.com/teamcapybara/capybara#using-capybara-with-minitest，因为在测试中设置 Capybara.default_driver = Capybara.javascript_driver 不会达到您想要的效果。
从 Rails 4.2 升级到 Rails 5.0 时，我的 issue/symptoms 与 OP 完全相同。我终于从注意到数据库时间太长中弄明白了——事务固定装置在它们应该被禁用的时候被启用了。我不确定是什么改变导致了这个默认翻转，但通过更明确地禁用事务固定装置，我能够解决这个问题。
更新
test.log显示服务器正在响应我们的测试并呈现页面。- 闹鬼失败
Capybara::Poltergeist::StatusFailError: Request to 'http://127.0.0.1:50712/computers' failed to reach server, check DNS and/or server status - Timed out with no open resource requests。
Poltergeist 无法连接到服务器。
我尝试了许多变体，包括：
- 更长的超时时间（最多 300 秒）。
- 正在将 Capybara.app_host 设置为 www.example.com、localhost 或 127.0.0.1。
- 删除 phantomjs_options.
- 正在从
static_controller.rb中删除force_ssl if: :ssl_configured?。 - 渲染
users/sign_in没有布局以消除外部 javascript。 - 将测试更改为调用
new_user_session_path、new_user_session_url和/users/sign_in。 - 运行
RAILS_ENV=test rake assets:precompile在 运行 测试之前（手动）。
当我运行rails s -e test时，我可以打开URL127.0.0.1:3000/users/sign_in.
这是我遇到的错误：

- 切换到 Puma
- 为 Minitest 添加代码
- 在test_helper.rb中设置
Capybara.default_driver = :poltergeist错误地停止运行宁rack_test。 - 正在从测试中删除

它显示试图访问“http://127.0.0.1/users/sign_in”的事实告诉您某处存在配置错误，因为那里应该有一个端口号（水豚从未 运行 对其进行测试端口 80）。
首先，您设置了 Capybara.server_port = 3000。您是否需要这样做而不是让 Capybara 分配一个随机的空闲端口？如果你确实需要修复它，3000 是一个糟糕的选择，因为这会阻止你在测试 运行.
其次，您设置了 Capybara.app_host。你真的需要设置这个吗？当您要针对外部站点进行测试，或者如果您有特殊的 IP 要求时，通常会使用它。如果你真的需要设置 app_host 你可能还需要设置 Capybara.always_include_port = true
所以两个解决方案
取消设置
app_host和server_port，让 Capybara 管理它们将您的固定服务器端口更改为 3000 以外的端口并添加
Capybara.always_include_port = true
此外，您可能还想阅读 https://github.com/teamcapybara/capybara#using-capybara-with-minitest，因为在测试中设置 Capybara.default_driver = Capybara.javascript_driver 不会达到您想要的效果。
从 Rails 4.2 升级到 Rails 5.0 时，我的 issue/symptoms 与 OP 完全相同。我终于从注意到数据库时间太长中弄明白了——事务固定装置在它们应该被禁用的时候被启用了。我不确定是什么改变导致了这个默认翻转，但通过更明确地禁用事务固定装置，我能够解决这个问题。
