Python Selenium Webdriver add method to Webelements/ custom 'assert' statement

I’m trying to add a few methods to WebElements that I use frequently. I figured out how to make it work, but now my assert statements fail. Here is what I have. How do I get my assert to work?

methods

WebElements

assert

def is_below(self, above_element):
below = self.location['y']
above = above_element.location['y']

self.assertLess(above, below)

WebElement.is_below = WebElement_is_below


In reality, this is all the logic I am trying to figure out:

class ModifiedTestCase(TestCase):
def is_below(self, above_element):
below = self.location['y']
above = above_element.location['y']

self.assertLess(above, below)

WebElement.is_below = WebElement_is_below


class SeleniumTest(ModifiedTestCase):

def test_web_page(self):

above_element = self.find_element()
below_element = self.find_element()

below_element.is_below(above_element)


The error I get is “WebElement has no attribute assertIn”. I know I can pass it a driver argument, but that defeats some of the simplicity.

So I figured out a solution. I used an assert statement.

assert

class ModifiedTestCase(TestCase):
def WebElement_is_below(self, above_element):
below = self.location['y']
above = above_element.location['y']

assert above < below, f'"below" > "above"'

WebElement.is_below = WebElement_is_below


class SeleniumTest(ModifiedTestCase):

def test_web_page(self):

above_element = self.find_element()
below_element = self.find_element()

below_element.is_below(above_element)
