摘要：
The invention provides a test arrangement for testing circuit units under test (101, 101a-101n) having a test apparatus for holding the circuit units under test (101, 101a-101n), input/output channels (DQ0-DQn) for connecting the circuit units under test (101, 101a-101n) to the test apparatus and for data interchange, and test mode output channels (103, 103a-103n) for outputting a test result signal (104, 104a-104n), where at least one diversion unit (102, 102a-102n) for connecting one of the test mode output channels (103, 103a-103n) to one of the input/output channels (DQ0-DQn) is provided in the circuit units under test (101, 101a-101n) so that the test result signal (104, 104a-104n) which is output from the circuit unit under test (101, 101a-101n) can be diverted from the circuit unit under test (101, 101a-101n) to a prescribable one of the input/output channels (DQ0-DQn).
