Unit Testing Framework for Embedded Component Systems

Effective construction of large, complex embedded systems involve the enhancement of potential reusability by dividing the software into subsystems and converting them into distinct parts (i.e., component-based development (CBD) for embedded systems). CBD can be used to improve development efficiency and reduce costs and is also applied to ensure software reusability: however, there are few approaches for testing CBD systems. General CBD systems do not provide methods for evaluating whether each component behaves as expected, making it necessary to manually connect individual components, which makes it difficult to test and fix bugs. To address these issues, this paper describes a unit testing framework for the embedded component systems (called TECSUnit), allowing the assessment of the behavior of each component. This framework increases the efficiency of testing component systems based on a design focusing on flexibility and efficiency.
