Using Dependency Information to Select the Test Focus Within the Integration Testing Process

Existing software systems consist of thousands of software components realizing countless requirements. To fulfill these requirements, components have to interact with or depend on each other. The goal of the integration testing process is to test that the interactions between these components are correctly realized. However, it is impossible to test all dependencies because of time and budget constraints. Therefore, error-prone dependencies have to be selected as tests. This paper presents an approach to select the test focus in the integration test process. It uses dependency and error information of previous versions of the system under test.
