Visual Testing (VT) Practice Exam 2025 - Free VT Exam Practice Questions and Study Guide

Mitigating flaky tests is essential in maintaining the reliability of visual testing outcomes. Ensuring consistent environmental conditions is a significant strategy because variations in the environment can lead to different results in visual tests. Environmental factors such as screen resolution, browser versions, operating systems, and even font rendering can all impact the visual appearance of an application. By standardizing these variables, visual tests are more likely to produce consistent results, reducing the likelihood of false positives or negatives. This consistency helps developers and testers confidently rely on test results, thus streamlining the testing process and reducing the time spent on diagnosing issues that arise from environmental inconsistencies.

The other approaches, while they may play a role in a broader testing strategy, do not directly address the primary cause of flaky tests. Simply increasing the number of test scripts may lead to a greater chance of encountering flaky tests if environmental factors are not controlled. Simplifying the testing frameworks might improve usability but won't necessarily resolve inconsistencies. Furthermore, completely eliminating automated tests would undermine the benefits of automation in testing, which is to enhance efficiency and accuracy.
