Which issues impact test planning and execution activities?

Several issues can impact test planning and execution activities, including unclear requirements, which can lead to inadequate test coverage, and resource constraints like limited time, budget, or personnel. Additionally, changes in project scope or technology can create challenges in maintaining test relevance and accuracy. Poor communication among stakeholders may also result in misalignment of expectations and priorities, further complicating the testing process. Finally, insufficient test environment setup can hinder execution and lead to unreliable results.
