With the exponential growth of software complexity, and in order to keep under control the cost and time of critical embedded application development, a continuous testing infrastructure is a must have feature.

Not only should software tests be run early and automatically each time a developer pushes a new code commit in the system, but furthermore, as developers typically never get enough physical board to test from, it is a key to initially run tests in a virtualized environment. Nevertheless we should keep enough real hardware in the loop to limit virtualization/reality deviation and ensure developers can transparently move tests from virtualization to the real world.

This presentation shows how virtualization may ensure early code integration to reduce development/testing cycle, while at the same time keeping track of real hardware, to ensure that the application is also running correctly on the final production device. Finally it gives feedback on the different challenges Iot.bzh faced while deploying its solution of continuous tests. Then focuses on the way virtualization and real targets can be combined to offer to developers a complete and efficient CI infrastructure.

This talk was presented at Automotive Linux Summit and at FOSDEM 2022
