Using assert_select on strings
assert_select is awesome for testing dom objects – but it relies on using the standard rails response cycle. How can I use assert_select on to find dom elements in a standard string?
Stub the response object!
def test_big_selector_helper # the response requires a content_type - just set it to "text" @response.stubs(:content_type).returns "text" # big_element_selector is the helper method I'm testing in this instance # replace with the string that you want to test @response.stubs(:body).returns big_element_selector # now you can use assert_select assert_select "ul" do assert_select "li", :count => 3 end
