Development of test design process for specification-based testing LTE Radio Access Network

Purpose and goal

The goal of the project was, starting with adoption of existing test generation techniques, improving testing of component of LTE mobile network, to identify domain-specific problems and develop methods to cope with them. The study was done on usability of different modeling languages. Application of model-based testing to testing Radio Unit was explored. We developed an approach to automate trace log generation in a model-based way in order to perform negative testing of automated test cases that analyze logs. We also used constraint programming to analyze logs automatically.

Results and expected effects

Results of the project were published in the proceedings of 2 international conferences and 2 international workshops. The project leader presented results of the project at 3 international conferences and 5 workshops. She participated in workshop organized by Uppsala University and gave a talk at the department seminar. The project leader supervised Master thesis projects at Ericsson and Uppsala University. The project leader increased her competence in the area of software testing by taking courses and participating in certification program Advanced level test analyst.

Approach and implementation

The project leader worked 50% at Uppsala University during the project time. The project leader had regular meetings and discussions with researchers from the Department of Information Technology at Uppsala University. Part of the work was done also in collaboration with researcher from SICS. The project leader spent some time abroad during project time. She participated in conferences and visited research centers at Radboud University in Nijmegen, Simula Research lab in Oslo and Ecole Nationale Superiere d´Informatique and Enterprise in Paris.
