In ch11l032, this is introduced, to test the HTML5 validation:
self.wait_for(lambda: self.browser.find_elements_by_css_selector(
'#id_text:invalid'
))
However, it isn't testing anything.
Because we are using find_elementS_by_css_selector(...) if the element is not found an empty list will be returned and no exception will be raised. Therefore our wait_for immediately returns after the first try and we didn't test anything (try making it fail on purpose by looking for a different id, it won't fail).
To fix that, the solution is simple, remove the S. That way it'll either find that one element, or raise a NoSuchElementException, which is a WebDriverException, so our wait_for works as expected 🙂
