Abstract

A test device and a test method, the test device comprising a bus controller for the transmission and reception of bus messages, the bus controller having a message memory for offering transmission data for bus messages, the message memory having a memory capacity for a bus message sequence with bus messages to be transmitted within a single transmission cycle or a transmission cycle sequence. The test device includes an intermediate memory for the storage of transmission data for bus messages with a larger storage capacity than the message memory. The test device furthermore comprises a transmission preparing means for reading transmission data from the intermediate memory and for writing, in advance of reading of the bus controller, to the message memory of the bus controller so that the bus message sequence is expanded by additional bus messages which are transmitted by the bus controller within the transmission cycle or the transmission cycle sequence on the motor vehicle bus.
