Test Design as Code: JCUnit

In a development process where testing is highly automated, there is a major challenge to cope with issues such as huge test size and test stability. In this paper, we propose a model-based testing (MBT) tool called JCUnit, which generates a test suite from a model given as a Java class. Unlike other tools, it is designed to generate small and stable test suites and supports various popular models. With this tool, developers can apply MBT approach to their products without learning domain-specific language of proprietary MBT tools. Moreover, features such as portability and pluggability make it useful in a wide range of phases from unit testing to system testing. As a result, the efforts required in practical software testing will be reduced.
