Job description

In DAF we make software for 2 big controllers in the truck: the powertrain controller and vehicle controller. Both these platforms have a similar architecture, in which the important part is that we build applications on top of a basic software layer. The applications are made in Matlab Simulink.
For unit testing, we use the unit testing framework that Simulink provides, this allows us to do Model In the Loop testing (MIL). On top of that, we created an environment in which we create libraries (shared objects, or .so files) from those Simulink applications. Using Python we can call functions in those libraries, which allows us to perform automated integration level tests. Those tests are Software In the Loop (SIL) tests.
At this moment the SIL test is tightly coupled with the applications (.so) files. We would like to create a framework in where the tests are decoupled from the application. In short: you run the test, but whether that test is executed on the applications (.so files) or on the real hardware is determined by the framework.
Therefore we would like to investigate 3 parts: How can we create a virtual environment that always runs the latest version of each application (50 in total). How can we use a broker that allows decoupling of tests and applications. Finally, how can we setup a test framework that can be used on all levels (MIL, SIL, HIL)
This task includes:

• Learning how our development process works and how we perform different levels of testing (MIL, SIL and HIL)
• Investigating what kind of message broker platforms there are and which one can be used to integrate with our integration test environment
• Choosing a platform and integrating it with our integration test framework
• Investigating if this platform can be coupled with hardware

• Investigate if this virtual environment can be connected to the vehicle CAN busses
• Check if we can use this environment for our other platforms and if so: make that happen
