Hi
I'm using RSpec in with Ruby on Rails. I've made a helper module
method that generates some HTML and would like to create a rspec
test to validate this HTML. I can of cause use regex to validate it
as a string, but would much rather validate it by traversing the DOM
and checking that the elements I expect is present. Any pointers?
No - that's not really an option. The rails stack has no idea about a
DOM.
One option, though, is to stub methods and use message expectations.
For instance, if you had a helper like the following:
module MyHelper
def my_method(a_name)
link_to(a_name, {:controller => "foo", :action => "foo"})
end
end
You'd be able to write a spec like the following:
it "should link with the correct name" do
helper.should_receive(:link_to).with("foo", {:controller =>
"foo", :action => "foo"})
helper.my_method("foo")
end
Hope that helps,
Scott
