Question

Quizplus · Accepted Answer

Defining expected results before execution helps in reducing the possibility of incorrect results by providing a clear understanding of what should happen during the testing process. This ensures that the testing process is more accurate and reliable, leading to better quality software. While defining expected results can also assist in test automation and improving test efficiency, reducing the possibility of incorrect results is the most important reason for defining expected results before execution. Improving the design of the software is not directly related to defining expected results.
