Rspec: how to spec request.env in a helper spec?

Question

In my helper module, I have:

def abc(url)   ...   if request.env['HTTP_USER_AGENT']     do something   end end 

In my spec file, I have:

  describe "#abc" do       before(:each) do   @meth = :abc    helper.request.env['HTTP_USER_AGENT'] = "..." end it "should return the webstart jnlp file" do   @obj.send(@meth, "some_url").should .... end end 

When I run the spec I have this error:

undefined local variable or method `request' for <ObjectWithDocHelperMixedIn:0x00000103b5a7d0> 

How do I stub for request.env['...'] in my specs?

Thanks.

Answer 1

If you're using rspec-rails, you might be able to use controller.request in your helper tests.

Answer 2

Well, you've almost nothing to do:

before(:each) do   @meth = :abc    request.env['HTTP_USER_AGENT'] = "..." end 

I just gave this another try and this passes:

#in helper def foo   request.env['HTTP_USER_AGENT'] end  #spec it "foo" do   helper.request.env['HTTP_USER_AGENT'] = 'foo'   expect(helper.foo).to eq 'foo' end
