Unit Testing of Database-Driven Java Enterprise Edition Applications

摘要

The Java Enterprise Edition (Java EE) platform and its persistence API are widely adopted technologies to develop applications that interact with database systems. Many control flows of these applications strongly depend on a specific database state. This paper presents an automatic test-case generation approach for applications in this environment. The approach generates both test data for the application's input, as well as entity objects for the different database states that are required to cover a respective control flow. We integrate constraints from symbolically executing a control flow with constraints on a required database state. We also support typical Java EE functionalities in the symbolic execution, e.g. dependency injection. An experimental evaluation shows an increase in control-flow coverage by our approach.
