How can versioning of visual tests improve test fidelity?

Versioning of visual tests enhances test fidelity by effectively tracking visual changes over time. This systematic approach allows teams to monitor alterations in the user interface or design elements as the development progresses, ensuring that any updates are consistently evaluated against previous iterations. By maintaining a version history, testers can compare visuals against earlier benchmarks to identify unexpected discrepancies, thus ensuring that the application behaves as intended and maintains its visual integrity through various development cycles. This process is critical in maintaining quality assurance since it provides a clear audit trail of changes and assists teams in managing regressions or anomalies in visual presentations, leading to more reliable test outcomes.
