A method, apparatus and computer readable medium for call quality testing is presented. A query is transmitted over a communications network from a first location to a second location. The query results in an audio signal at the second location, which is received at the first location. The audio signal is analyzed by comparing the signal with a reference signal clip. A statistical parameter is generated, the statistical parameter indicative of a quality of the received signal.

Methods and apparatus providing call quality testing

A method is disclosed for testing applications that include non-deterministic behavior. The presently disclosed method generates test code for testing deterministic behavior of an application. When instances of non-deterministic behavior of the application being tested are encountered, the method provides acceptable alternate behaviors, such that the non-deterministic behavior can be effectively tested. The method may be implemented as a software test tool that utilizes a graphical programming interface to make the test generation simple and easy to use.
