Description

Background

Testing to make sure a product behaves as expected is as important as the product itself. It is also very important to be confident that the product continues to meet the old requirements when new features are added; and also that the new features can rely on the baseline functionality when being developed.

In this master thesis you would get the chance to dig into test strategies and automated test loops in the day to day work of an RnD software developer.

You'd specifically research in the topic of random test data generation and how it could be applied together with other, static tests, to increase the quality of the software product. A key point would be to investigate how it could integrate into automated test loops with as small impact as possible on the RnD delivery flow.

As B. Rollison states in [1], "Testing is the most challenging job in software development. The software tester must select a small number of tests from countless possible tests and perform them within a limited period of time, often with too few resources."

For example; if a test runs successfully every day, for 100 days, with static configuration. You'll be very confident that the product meets this static requirement. However, as the number of input parameters grows the coverage of such a test will be more limited and even if you create more static tests, you'll still be very limited in overall coverage. This is where random input in combination with time could help out to bring in more coverage.

Thesis Description

Topics that could be covered depending on your interest:

  • Research what have been done in this area earlier
  • Implement random generation in Python
  • Modeling and parameterization of random data generation, to achieve random test close to real use cases. Parameters may have restrictions based on other parameter settings.
  • Investigate what kind of mix of static, random and potentially other test-strategies are suitable for certain environments to get as good coverage as possible.
  • Investigate what level of test is most suitable for random tests, low level function tests or larger modules?
  • Investigate and propose how the test-strategy could be integrated in an automated test-loop and to describe ways of working when finding issues or when new parameters are added to the product.
  • Implement the strategy in existing Ericsson automated test loops using Python.
  • Writing a thorough thesis report on the work done

The positions are placed within Uplink Layer 1 domain in Baseband Lower Products sector of Product Development Unit Baseband Software. The baseband SW implements the layer 1 and layer 2 protocol layers of the Ericsson RAN product family. The SW is deployed on Ericsson baseband boards and on Ericsson radio boards where the baseband SW interacts with layer 3 SW, Radio modules and O&M.
