About the job

Preamble
A thesis project is a perfect way to get a closer contact with Scania and build relations for your future. Many of our employees started their career at Scania with their thesis project.

Background and Description of the Assignment
A test plan is one of the fundamental testing artefact that drives the testing process, and as such it has a major impact on the efficiency and effectiveness of the testing activities. For agile test teams that are following iterative delivery cycle in which the testing efforts are divided into sprints, the test plan is a continuously evolving document that changes rather fast. As a consequence to the agile way of working, the test team is responsible for updating the existing or generating a completely new test plan for every test round. Additional challenge for generating efficient test plans within certain parts of Scania is the high variability of the products. This means that a specific testing task is always applicable to some specific product or family of products (for instance, some functionality is available in trucks but not in busses, or it might require a specialized variant of a truck, etc.).

While some testing levels abstract away from the variability of the products’ features, at the complete vehicle integration testing level one must account for the variability of the products as the testing is performed in a Hardware-in-the-Loop (HIL) environment, which means that a specific feature might require setting up a specific configuration of the HIL environment in order to make it adequate for a specific verification task. Given that setting up a new configuration in the HIL environment is a complex and time consuming process, it poses significant constraints on the testing plan, especially with respect to its efficiency. In this project, we aim to explore whether the generation of the test plan can be completely automated for the complete vehicle integration testing at Scania. The starting premise is that the tasks for a specific test round are specified in an issue tracking program (for instance jira). Then, the goal is to propose and implement a completely automated solution for generating a test plan based on the existing set of tasks for that particular test round.

The generated test plan must be optimized for at least the following two parameters:

  1. the maximal set of tasks that can be run in a specific test round, and
  2. highest possible utilization of the HIL environment (minimize the number of reconfigurations for the HIL environment)

Another very important aspect that the automated test planning solution should provide is changelog history, and a visualization mechanism for displaying it in a user-friendly manner. That means that the as the test plan evolves, the previous version of the test plan is logged (saved) for the purpose of retroactive analyses.

Finally, the automated solution must be compared against the current state-of-the-practice manual approach for test plan development and maintenance in order to draw a conclusion about the efficiency and usefulness of the automated approach against the current approach.
