Rails 3,黄瓜0.9.4,Capybara 0.4.0
Given /^I visit subdomain "(.+)"$/ do |sub|
Capybara.default_host = "#{sub}.example.com" #for Rack::Test
Capybara.app_host = "http://#{sub}.example.com:9887" if Capybara.current_driver == :culerity
end
如果我运行黄瓜功能/ subdomain.feature它工作,但如果我运行黄瓜功能失败！这是令人难以置信的,但它是真实的.我记录了当前的网址,它是subdomain.example.com的黄瓜功能/ subdomain.feature和www.example.com黄瓜功能一个场景与
Scenario: subdomain scenario Given I visit subdomain "subdomain"
在这两种情况下！
我不知道原因…
有没有最好的方法来测试subdomains与水豚？
解决方法
好的,这里应该是一个相当直截了当且容易理解的黑手起家Capybara,产生所需的行为,即能够在每次切换子域时创建一个新的会话.这对于用户在一个域中注册的站点(其导致为其帐户创建的子域),然后最终需要导航到该子域是有用的.
首先(这部分在其他解决方案中相当普遍),然后给自己一个方法来改变黄瓜级别的Capybara.default_host.我这样做：
Then /^I switch the subdomain to (\w+)$/ do |s|
Capybara.default_host = "#{s}.smackaho.st"
end
在您要使用新子域的时候,将此步骤保存在黄瓜功能中.例如：
When I open the email Then I should see "http://acme.rightbonus.com/users/confirmation" in the email body Given I switch the subdomain to acme When I follow "Click here to finish setting up your account" in the email Then I should be on the user confirmation page for acme
现在为了使这项工作的神奇monkeypatching.基本上,您希望Capybara足够聪明,以检测子域是否已更改并重置其RackTest会话对象.
# features/support/capybara.rb
class Capybara::Driver::RackTest
# keep track of the default host you started with
def initialize(app)
raise ArgumentError,"rack-test requires a rack application,but none was given" unless app
@app = app
@default_host = Capybara.default_host
end
def process(method,path,attributes = {})
reset_if_host_has_changed
path = ["http://",@default_host,path].join
return if path.gsub(/^#{request_path}/,'') =~ /^#/
path = request_path + path if path =~ /^\?/
send(method,to_binary(path),to_binary( attributes ),env)
follow_redirects!
end
private
def build_rack_mock_session # :nodoc:
puts "building a new Rack::MockSession for " + Capybara.default_host
Rack::MockSession.new(app,Capybara.default_host || "www.example.com")
end
def reset_if_host_has_changed
if @default_host != Capybara.default_host
reset! # clears the existing MockSession
@default_host = Capybara.default_host
end
end
end
此补丁适用于Capybara 0.4.1.1,除非经过修改,否则可能无法使用不同的版本.祝你好运.
