The event type is the type of error the Event Handler will react to. There are four event types. They correspond to common errors which happen during test execution.
If a component in the AUT cannot be found, an error occurs. The component might not be found if it has been changed, is not (yet) visible or has been deleted.
For some actions, you can specify an expected value to check. If the value you specify is not true, then a check failed error occurs.
Action errors occur when an action cannot be carried out on a component, when the data is invalid (e.g. an invalid menu path) or when an action takes too long and there is a timeout.
Configuration errors occur when there is an internal problem, for example a changed implementation class in the XML file.
