What are some common challenges faced by Pytest Python Selenium automation engineers when maintaining test suites over time?

Automation engineers using Pytest, Python, and Selenium often encounter challenges like test flakiness due to dynamic web elements, frequent UI changes that require updates to selectors, and managing dependencies between tests. As projects grow, maintaining clear test structure and ensuring tests remain reliable and independent is crucial. Engineers frequently collaborate with developers and QA teams to prioritize test coverage and quickly address issues that arise from application changes.
