Install my assert_xpath, and activate its assert_javascript.
(This currently uses Javascript-PurePerl, and I hope to upgrade that to a Ruby
solution shortly.)
Each page needs a test case like this:
def test_foo_is_tidy
get :foo
assert_tidy
end
If you put "Strict XHTML" into your DOCTYPE, then tidy should enforce that.
Next, to test an Ajax call, you would do this:
xhr :get, :xhr_change_the_frob
assert_js_replace_html :frob do
assert_xpath :'form/input[ @name = "baz" and @value = "42" ]'
end
assert_js_replace_html lexes the returned JavaScript, finds the
Element.update()
command, and parses the XHTML inside it. The do-end block sees that XHTML, so
you can do further queries on it.
All these tests will fail if the XHTML has a single ill-formed tag.
At my day-job, we enforce strict "Transitional XHTML", even though we only
target wildly forgiving browsers, and even though our production code could get
away with sloppy HTML. We do this because enforcing XHTML makes all our view
tests much easier to write.
