What metrics are important for assessing visual testing effectiveness?

The selected answer highlights critical metrics for evaluating the effectiveness of visual testing. Firstly, the rate of detected visual defects is paramount since it directly measures the capability of the visual testing process to identify discrepancies between the expected and actual appearance of the application. A higher detection rate indicates a more effective testing process.

Test execution time is also significant, as it reflects the efficiency of the testing process. If tests are executed quickly without compromising quality, it can lead to faster development cycles and more efficient workflows.

Finally, the percentage of passed tests serves as an indicator of the overall stability and visual consistency of the application. A high percentage suggests that the application meets visual standards and behaves as expected under various conditions.

These metrics combined provide a comprehensive view of both the effectiveness and efficiency of visual testing efforts, which are essential for maintaining high visual quality in software products. Other options, while potentially relevant in different contexts, do not focus specifically on the assessment of visual testing effectiveness.
