    This actor tests for exceptions that are expected to occur when running a test model. When an exception is thrown by the model, this actor is invoked. It has two working modes, training mode and non-training mode. If in training mode, this actor handles an exception by recording the exception message. If not in training mode, this actor first compares the previously stored (assumed correct) message to the exception message and then throws an exception if the two messages are not the same. Also, if a test runs to completion without throwing an exception, this actor throws an exception in its wrapup() method. An exception is expected.

      • trainingMode

        public SharedParameter trainingMode
        Deprecated.
        If true, then collect the exception message and set the correctExceptionMessage parameter with the content of the exception. This parameter is a boolean, and it defaults to false. It is a shared parameter, meaning that changing it for any one instance in a model will change it for all instances in the model.

      • correctExceptionMessage

        public StringParameter correctExceptionMessage
        Deprecated.
        The correct exception message to be compared against.

        public static final java.lang.String TRAINING_MODE_ERROR_MESSAGE
        Deprecated.
        Exception message that is used if we are running under the nightly build and the trainingMode parameter is true.
