When testing multimedia software applications,
we need to overcome important issues such as
the forbidding size of the input domains,
great difficulties in repeating non-deterministic test outcomes,
and the test oracle problem.
A statistical testing methodology is proposed.
It applies pattern classification techniques enhanced
with the notion of test dimensions.
Test dimensions are orthogonal properties of associated test cases.
Temporal properties are being studied in the experimentation in this paper.
For each test dimension,
a pattern classifier is trained on the normal and abnormal behaviors.
A type of failure is said to be classified if it is recognized by
Test cases can then be analyzed by the failure pattern recognizers.
Experiments show that some test dimensions are more effective than others
in failure identification and classification.
Keywords: Software testing, test dimensions, multimedia application testing, failure identification, failure classification.
