assert-element 0.4.0

Simple TestCase assertion that finds element based on it's path and check if it equals with given content.

Simple TestCase assertion that finds element based on it’s path and check if it equals with given content.

This is more useful than the default Django AssertContains because it will find the element and show differences if something changed. The test also tries to ignore differences in whitespaces as much as possible.

Quickstart

Install by:

pip install assert-element

Usage in tests:

from assert_element import AssertElementMixin

class MyTestCase(AssertElementMixin, TestCase):
    def test_something(self):
        response = self.client.get(address)
        self.assertElementContains(
            response,
            'div[id="my-div"]',
            '<div id="my-div">My div</div>',
        )

The first attribute can be response or content itself. Second attribute is the path to the element. Third attribute is the expected content.
