Link: exploiting the web of data to generate test inputs

Applications that process complex data, such as maps, personal data, book information, travel data, etc., are becoming extremely common. Testing such applications is hard, because they require realistic and coherent test inputs that are expensive to generate manually and difficult to synthesize automatically. So far the research on test case generation techniques has focused mostly on generating test sequences and synthetic test inputs, and has payed little attention to the generation of complex test inputs.
