Now that there's only one test left in the PR, the subject doesn't correspond
to the content. You're no longer updating instructions for manual tests, you're
*automating one manual test*.
test/jdk/java/awt/List/MouseDraggedOriginatedByScrollBarTest.java line 124:
> 122: } catch (Exception ex) {
> 123: throw new RuntimeException("Can't create robot");
> 124: }
Suggestion:
Robot robot = new Robot();
The `test` method has the `throws` clause with `Exception`, just let
`AWTException` propagate.
test/jdk/java/awt/List/MouseDraggedOriginatedByScrollBarTest.java line 129:
> 127: robot.setAutoWaitForIdle(true);
> 128:
> 129: // Focus default button and wait till it gets focus
The comment is confusing, it doesn't correspond to the code below.
test/jdk/java/awt/List/MouseDraggedOriginatedByScrollBarTest.java line 132:
> 130: EventQueue.invokeAndWait(() -> {
> 131: loc = list.getLocationOnScreen();
> 132: width = list.getWidth();
Suggestion:
Point p = list.getLocationOnScreen();
p.translate(list.getWidth(), 20);
loc = p;
Then `width` becomes redundant.
test/jdk/java/awt/List/MouseDraggedOriginatedByScrollBarTest.java line 139:
> 137: Point p = MouseInfo.getPointerInfo().getLocation();
> 138: robot.mouseMove(p.x, p.y + 1);
> 139: }
Suggestion:
for (int i = 0; i < 30; i++) {
robot.mouseMove(loc.x, loc.y + 1);
}
You may copy `loc` into a non-volatile local variable (micro-optimisation).
