Testing is one of the most important and time consuming steps in software development. Testing database applications is much more challenging because the testing involves a stateful component: the backend database. While the testing of database application is still in its infancy, the SIKOSA project presents three tools (HTDGen,HTTrace and HTPar) which address the test database generation and the efficient test run execution problem. As part of future work, we plan to extend the tool suite by adding tools on testing the scalability of database applications. Furthermore, we plan to extend existing tools to deal with the evolution of test runs and test databases.
