Description

Technical Field

[0001] The present invention relates to the technical field related to testing equipment, and relates to a computer screen or touchpad testing equipment and a screen test trajectory generation program, and in particular to a multi-motion trajectory computer screen or touchpad testing equipment and a screen test trajectory generation program. Background Art

[0002] Computer screen and touchpad test items mainly include LCD test, Touch pad test, fingerprint test, LCD two-finger test and ten-finger test. LCD test is to draw different graphics such as quadrilateral, "cross", "X", diagonal line, etc. on the screen with different pen speeds and pressure according to the customer's test requirements by capacitive pen or electric control pen; Touchpad test is to click the left and right keys on the touchpad and draw various graphics such as boxes and diagonal lines, and then move the fixed coordinate point position on the touchpad according to the pressure; fingerprint test is to automatically test fingerprints according to different models. Generally, computer screen, touchpad and button tests require sliding and pressing at different positions on the screen, touchpad and buttons. These positions are actually ever-changing and the frequency of change is very frequent. Diversification will require a large amount of motion trajectory data at any time.

When the amount of data is large, the program will become complicated and difficult to understand, difficult to manage, difficult to analyze, and difficult to control the accuracy. When the program needs to be modified in the future, it is necessary to fully understand the original program fair process, which delays the efficiency of line change debugging and makes it difficult for programmers to provide multiple services at the same time.
