A method for automatic error diagnosis in a test environment is provided. The method comprises the step of providing a plurality of test logs associated with known types of failures, each comprising a set of files. The method further comprises the step of arranging the plurality of test logs in a defect database. Moreover, the method comprises the step of transforming the set of files of the plurality of test logs into vectors adapted to be fed into a machine learning model.

A method is provided for transforming message logs into images. The method comprises the step of receiving a message log comprising a plurality of messages. The method further comprises the step of selecting a content of at least one message. In addition, the method comprises the step of transforming the content block-wise into decimal numbers. Furthermore, the method comprises the step of associating each decimal number with a color value thereby translating each message into a sequence of symbols. Moreover, the method comprises the step of generating an image from the symbols of the plurality of messages.

A method for reporting scheduling decisions by a communication tester is provided. The method comprises the steps of establishing a communication between the communication tester and a device under test, and creating a message log during the communication with the aid of the communication tester. In this context, the message log comprises reports with all negative scheduling decisions.

An automated evaluation of test logs for the testing of telecommunications equipment includes a probabilistic model that links possible events in a test log with possible causes for the event. Probability values for possible causes are calculated from the probabilistic model and a search result, and a reference to a possible cause is provided in an output based upon the calculated probability values.
