In recent years, Continuous Integration (CI) has become a widespread practice in software development thanks to the many benefits it offers. Most notably, it allows for earlier bug detection, leading to improved code quality and reliability. However, this paradigm has had a hard time making its way into the domain of embedded systems due to the problems that stem from interacting with real hardware, such as setting up the environment, repeatability of the tests, and the cost of the whole infrastructure. This thesis aims to develop a testing framework with Hardware-In-the-Loop to enable CI practices in the development process of Arduino Cores.
