rspec 路由测试和主机 [英] rspec route testing and hosts

问题描述

我看到我可以像这样使用 rspec 测试路由:

I see I can test routes with rspec like this:

get("/").should route_to("welcome#index")

但我有基于主机名或主机名部分的限制，以及几个主机名之间的重定向.测试时如何指定主机名?

but I have constraints based on the hostname or parts of hostnames and redirects between several ones. How do I specify a hostname when testing?

如何以正确的配置运行测试?我尝试打印 root_url 并得到:

How do I run the tests with proper configuration? I tried printing root_url and I got:

缺少要链接的主机！请提供 :host 参数，设置default_url_options[:host]，或者设置:only_path 为true

Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true

推荐答案

我每次运行 rspec spec/

整个错误实际上是:

Failure/Error: @user = Factory(:user)
     ActionView::Template::Error:
       Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
     # ./app/views/devise/mailer/confirmation_instructions.html.erb:5:in `_app_views_devise_mailer_confirmation_instructions_html_erb__980323237__638702928'
     # ./spec/models/campaign_spec.rb:21

以下行:

# ./app/views/devise/mailer/confirmation_instructions.html.erb:5:in `_app_views_devise_mailer_confirmation_instructions_html_erb__980323237__638702928'

实际上给了我一个提示，即设计是抛出错误的那个.

actually gave me the hint that devise is the one throwing out the error.

原来我还没有设置

config.action_mailer.default_url_options = { :host => 'localhost:3000' }

在 config/environments/test.rb(仅在 development.rb 中)

in config/environments/test.rb (only in development.rb)

添加配置选项清除了我的错误.我怀疑您正在使用其他需要相同选项集的 gem.

Adding the config option cleared out the errors on mine. I'm suspecting you're using other gems that requires the same option set.
