Nowadays embedded applications are integrated into simple consumer electronics to highly safety-critical control units. Whereas module tests may be implemented similarly compared to classical software development, the additional hardware component complicates the integration testing process dramatically. In addition to expensive and closed test systems, there are hardly any alternatives and innovative approaches to realize these types of tests. The underlying work deals with the realization of a combination of integration tests for embedded applications on electronic control units and the test approach of behavior driven development. Thereby, the possibilities of the synthesis and the applicability should be demonstrated. In the course of this, the work comprises the development of an API using the programming language Python to provide functions for testing applications on electronic units. The API is tested in combination with an existing test framework for creating behavior driven tests within a prototypical setup. In order to increase the significance of the evaluation results with regards to practical applicability, the realization is tested using an existing and running application project, which is provided by the cooperation partner. Both the status-quo analysis, the feedback presentation and the conducted expert interviews on the basis of a semi-structured guide indicate the successful implementation of the concept and confirm the applicability in practice. On the one hand, the evaluation reveals factors which state a clear advantage compared to classical test approaches and on the other hand, identifies current limitations and potential challenges.
