Jubula bases the success of an action on whether it was carried out or not. There are no implicit checks which verify the state of the application to check if the execution of an action actually had an effect. For example, if an action is carried out to click a button, this Test Step will be marked as successful even if the button is disabled. From Jubula 's perspective, a click was executed on the button component.
It is worth bearing this in mind if a test has failed, especially because of a ''component not found'' error. What may have happened is that a further component was not found due to a dialog still being in focus, because the "close" button was disabled, for example. Although a click was executed on this button, it did not have the desired effect. The test continued, but ran into problems.
