What are the challenges that can be faced while website test automation?

Please can anyone tell me what are the challenges that can be faced while website test automation.

These are some of the challenges that can be faced during test automation:

  • Requires more communication and collaboration in the automation testing team
  • Difficulty in selecting a correct tool for automation testing
  • Difficulty in running parallel test execution of multiple test cases
  • The automated testing resources should have a very strong knowledge of the automation testing frameworks design, and their implementation
  • One of the biggest challenges in test automation is to select the right testing approach.
