Estoy usando java.awt.Robot
para las pruebas de integración de mi aplicación Swing, pero tengo problemas para ejecutar mis acciones en el orden correcto. ¿Cómo puedo decirle al hilo que llama al robot.mousePressed(...)
que bloquee hasta que Swing termine de despachar ese evento? Aparentemente, robot.setAutoWaitForIdle(true)
no sirve.¿java.awt.Robot.waitForIdle() espera a que se envíen los eventos?
Aquí está mi demostración. ¡Espero que el "robot haya terminado!" mensaje para que siempre aparezca después de "Acción finalizó el bloqueo", pero en su lugar, a menudo sucede demasiado pronto.
