如何模拟 rspec 辅助测试的请求对象?

发布于 2024-09-28 20:52:19 字数 860 浏览 7 评论 0原文

我有一个视图辅助方法,它通过查看 request.domain 和 request.port_string 来生成 url。

   module ApplicationHelper  
       def root_with_subdomain(subdomain)  
           subdomain += "." unless subdomain.empty?    
           [subdomain, request.domain, request.port_string].join  
       end  
   end  

我想使用 rspec 测试这个方法。

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    root_with_subdomain("test").should = "test.xxxx:xxxx"
  end
end

但是当我用 rspec 运行它时,我得到了这个:

 失败/错误:root_with_subdomain("test").should = "test.xxxx:xxxx"
 `# 的未定义局部变量或方法“请求”`

谁能帮我弄清楚我应该做什么来解决这个问题? 我如何模拟此示例的“请求”对象?

有没有更好的方法来生成使用子域的网址?

提前致谢。

I've a view helper method which generates a url by looking at request.domain and request.port_string.

   module ApplicationHelper  
       def root_with_subdomain(subdomain)  
           subdomain += "." unless subdomain.empty?    
           [subdomain, request.domain, request.port_string].join  
       end  
   end  

I would like to test this method using rspec.

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    root_with_subdomain("test").should = "test.xxxx:xxxx"
  end
end

But when I run this with rspec, I get this:

 Failure/Error: root_with_subdomain("test").should = "test.xxxx:xxxx"
 `undefined local variable or method `request' for #<RSpec::Core::ExampleGroup::Nested_3:0x98b668c>`

Can anyone please help me figure out what should I do to fix this?
How can I mock the 'request' object for this example?

Are there any better ways to generate urls where subdomains are used?

Thanks in advance.

您必须在辅助方法前面加上“helper”:

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    helper.root_with_subdomain("test").should = "test.xxxx:xxxx"
  end
end

此外,为了测试不同请求选项的行为,您可以通过控制器访问请求对象:

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    controller.request.host = 'www.domain.com'
    helper.root_with_subdomain("test").should = "test.xxxx:xxxx"
  end
end

You have to prepend the helper method with 'helper':

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    helper.root_with_subdomain("test").should = "test.xxxx:xxxx"
  end
end

Additionally to test behavior for different request options, you can access the request object throught the controller:

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    controller.request.host = 'www.domain.com'
    helper.root_with_subdomain("test").should = "test.xxxx:xxxx"
  end
end

这不是您问题的完整答案,但为了记录,您可以使用 ActionController::TestRequest.new() 模拟请求。像这样的东西:

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    test_domain = 'xxxx:xxxx'
    controller.request = ActionController::TestRequest.new(:host => test_domain)
    helper.root_with_subdomain("test").should = "test.#{test_domain}"
  end
end

This isn't a complete answer to your question, but for the record, you can mock a request using ActionController::TestRequest.new(). Something like:

describe ApplicationHelper do
  it "should prepend subdomain to host" do
    test_domain = 'xxxx:xxxx'
    controller.request = ActionController::TestRequest.new(:host => test_domain)
    helper.root_with_subdomain("test").should = "test.#{test_domain}"
  end
end

我遇到了类似的问题,我发现这个解决方案有效:

before(:each) do
  helper.request.host = "yourhostandorport"
end

I had a similar problem, i found this solution to work:

before(:each) do
  helper.request.host = "yourhostandorport"
end

这对我有用:

expect_any_instance_of(ActionDispatch::Request).to receive(:domain).exactly(1).times.and_return('domain')

This worked for me:

expect_any_instance_of(ActionDispatch::Request).to receive(:domain).exactly(1).times.and_return('domain')
