This thesis work presents the development and implementation of a test automation framework for a Telematics Control Unit (TCU) installed in commercial vehicles, commissioned by a major automotive client. The project was carried out within Concept Quality Reply, an automotive business unit of Reply, with a focus on integrating automation, Agile, and DevOps methodologies to streamline the validation and testing process. The work involved identifying key elements suitable for automation within the project, followed by the selection and automation of test suites through an internal proprietary framework. The automation process was carried out in several key phases. First, the physical setup of the test bench was defined, including the TCU, the body vehicle simulation managed by CANalyzer, and the Secure Gateway Logger (SGW).
