|
|
* <li> {@link OverlappingTestBase#prepareControls()} - setup UI components
|
|
* <li> {@link OverlappingTestBase#performTest()} - run particular test
|

* Those methods would be run in the loop for each AWT component.
|
|
* <p>Current AWT component should be added to the tested UI by {@link OverlappingTestBase#propagateAWTControls(java.awt.Container) ()}.
|
|
* There AWT components are prepared to be tested as being overlayed by other (e.g. Swing) components - they are colored to
|
|
* {@link OverlappingTestBase#AWT_BACKGROUND_COLOR} and throws failure on catching mouse event.
|
|
* <p> Validation of component being overlayed should be tested by {@link OverlappingTestBase#clickAndBlink(java.awt.Robot, java.awt.Point) }
|
|
* See each method javadoc for more details.
