The testing protocol consistency process is controlled by test computer, from initiating data communication to end; The test data that the testing apparatus record is all, and the time of record DSRC Frame; Test computer judges according to preset program checkout data whether the communication data of OBU meets the requirements.
Test result is judged explanation:
Test result is compared with expected results, carries out test result and judges that 3 kinds of results are arranged.
(1) passes through
The uniformity test that test case is corresponding requires purpose to reach, and shows as consistent with expected results in form.Test result all reaches the requirement of uniformity test standard.For example, when carrying out the OBU test, the response time of OBU is in the official hour scope; The OBU response data is correct through the test computer checking; For the abnormality test example, the reaction of OBU meets the requirements.
(2) failure
The coherence request that test case is corresponding has at least a quilt to violate, and shows as with expected results inconsistently in form, occurs illegal test event simultaneously, perhaps comprises at least one wrong test item according to relevant regulation.For example, when carrying out the OBU test, the response time of OBU surpasses the official hour scope; The OBU response data is through the test computer validation failure; OBU does not have response or responds mistake for normal test case; For the abnormality test example, the reaction of OBU is undesirable etc.
(3) uncertain
