Expected results of Assertion Errors are not showing up when using Pytest and conftest.py file

Question

I am using Pytest to test my website content. I have a fixure in my conftest.py that creates a webdriver for other tests to reference. When an error occurs during a test run, only AssertionError is displayed, as opposed to the actual and expected values being tested in the assert statement.

Here is my conftest.py file:

import os

import pytest
from selenium import webdriver


@pytest.fixture(scope="session")
def setup(request):
    driver_path = os.path.join(os.path.dirname(os.path.realpath(__file__)), 'drivers')
    driver = webdriver.Chrome()
    session = request.node
    for item in session.items:
        cls = item.getparent(pytest.Class)
        setattr(cls.obj, "driver", driver)

    yield driver
    driver.close()

Here is my high-level test file:

import pytest

from validations import *


@pytest.mark.usefixtures("setup")
class TestOurServices:
    def test_our_services_direct_navigation(self):
        go_to_our_services(self.driver)
        validate_our_services_content(self.driver)

Then here is an example of the output:

This post helped solve the issue:

pytest assert introspection in helper function

I had assertions in helper functions such as validate_our_services_content from above. They were in a file called validations.py

Referencing the above issue I created an __init__.py file to declare those validations:

__init__.py

import pytest

pytest.register_assert_rewrite('validations')
