Abstract: The present invention performs automated testing on service applications using automatically generated logs, so that new testing applications do not need to be created for each new release of a service application. The invention further provides for testing of all aspects of the service application by accounting for all data and processes performed, and does so without interfering with the processing of the service application. An Automated Regression Tester (ART) captures and records data generated by the execution of an initial version of a service application. This data is recorded to a first test log. When a new or ported version of that service application is developed, the first test log is used by the ART to generated output that emulates the operating environment, including caller and user input, of the service application. The processing of the new/ported version of the service application is captured and recorded to a second test log.
