Abstract: A method of effectively testing whether a service bundle operates by changing the configuration and function of bundles included in a test tool for an OSGi service platform and a test tool using the method are provided. The OSGi service platform test tool includes a framework in which test cases are installed, an adaptor enabling the framework to function in a test execution environment, a director bundle providing a UI of a test tool, services that manage the test, and OSGi services, and an agent bundle relaying message movement with the test case bundle to a framework of a target host.
