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.
