Investigating Test Teams´ Defect Detection in Function test

In a case study, the defect detection for functional test teams is investigated. In the study it is shown that the test teams not only discover defects in the features under test that they are responsible for, but also defects in interacting components, belonging to other test teams´ features. The paper presents the metrics collected and the results as such from the study, which gives insights into a complex development environment and highlights the need for coordination between test teams in function test.
