Câu 7: CTAL-TAV4-0: Certified Tester Advanced Level - Test Analyst v4.0

You are testing an image recognition system. The system is based on a deep neural network. As input, the system receives an image (1000x1000 pixels) of a geometric figure - a triangle, square, or circle. The figure is one color and is depicted on a solid background of another color. The figure can be of any size and placed anywhere on the picture. The system classifies the figure on output as a triangle, square, or circle. If the system receives an image that does not meet the above requirements, it responds with “unrecognized shape.”You want to test the correctness of this system using metamorphic testing. Which of the following is NOT a valid metamorphic relation for this scenario?

1. A. Changing the position of the figure (but so that it is still visible in its entirety) does not change the system’s answer
2. B. Rotating the image 90 degrees to the right or left does not change the system’s response
3. C. Changing the figure's color does not change the system’s response
4. D. Scaling down the figure does not change the system’s response — đáp án hiện tại
