What are some common challenges Selenium Automation Engineers face when maintaining test scripts over time?

Selenium Automation Engineers often encounter challenges such as test script fragility due to frequent changes in application UI, leading to broken locators or outdated test cases. Maintaining a robust test suite requires proactive refactoring, implementing reliable locator strategies, and ensuring tests remain modular and reusable. Effective collaboration with developers and QA teams is essential to keep scripts aligned with application updates and to quickly resolve issues, which helps minimize test maintenance overhead.
