Abstract

Execution of a block test “retry” in a test environment with each block in the test sequence sent after the tester has determined that the previous block of data packets has met one or more prescribed test criterion. If a block sent by the DUT has not met the test criterion, a retry sequence is initiated to re-test the block. In another embodiment, a block test “retry” is executed where each block in the test sequence is sent and analysis of previously sent blocks is done in parallel with the sending of a subsequent block. If a previous block has not met the test criterion, a retry sequence is initiated whereby the tester and DUT step back to the block that failed to meet the test criterion and retry that block. If the retry meets test criterion, testing continues by resuming with the next untested block in the sequence.

Dependent claims

A method of testing a communication device comprising:

listening with a device under test (DUT) for a synchronization initiation message;
if said DUT fails to receive said synchronization initiation message within a synchronization initiation time interval, then listening again with said DUT for said synchronization initiation message;
if said DUT receives said synchronization initiation message within said synchronization initiation time interval, then transmitting with said DUT a synchronization response message, followed by at least one of
listening with said DUT for a synchronization confirmation message, and
executing with said DUT at least a portion of one or more of a plurality of communications of a block-partitioned data packet sequence;
and
if said DUT fails said at least one of
listening with said DUT for a synchronization confirmation message, and
executing with said DUT at least a portion of one or more of a plurality of communications of a block-partitioned data packet sequence,
then repeating said listening and transmitting with said DUT.
