We recently had multiple support requests revolving around Clicks and Item selections not working consistently. The Actions might work fine on one machine, but not on another machine when using the same code to test the same app.
Some clicks were working just fine, but other clicks were clicking the wrong location.
Lei did some debugging and found that Java was clicking the wrong area when the Display Scaling was not set at 100.
The debug logs we analyzed confirmed that all the calculations for the location of a component were the same (mostly) for a Component or a MenuItem when calculated with the information provided by the testing tool (Selenium). The difference for success or failure was in who performed the click.
When we used the tool (Selenium) to perform the click, it likely sent an onClick event directly to the component and did NOT use a real mouse click at coordinates. Those clicks would work. However, if the code had to revert (or preferred) a Java Robot click—which used a real mouse click at calculated coordinates—then those clicks will be off and fail when the Display Scaling is not set at 100.
Display Scaling may be a new feature of Windows 10, or maybe not. In any case, the Display Scaling needs to remain at 100 so that both types of tools will successfully hit the right coordinates on screen.
