1. A method for the automated evaluation of a test log for testing telecommunications equipment, the method comprising steps: providing a probabilistic model, which links a plurality of possible events in the test log with a plurality of possible causes; searching the test log for the occurrence of at least one of the possible events; calculating probability values for the plurality of possible causes with the probabilistic model and a search result; and providing an indication of at least one possible cause for the at least one of the possible events in the test log based on the calculated probability values.
