Executive Summary

An important goal of software testing is to achieve at least high structural coverage. To reduce the manual efforts of producing such high-covering test inputs, testers or developers can employ tools built based on automated structural test-generation approaches. Although these tools can easily achieve high structural coverage for simple programs, when they are applied on complex programs in practice, these tools face various problems, such as the External-Method-Call Problem (EMCP), where tools cannot deal with method calls to external libraries; the Object-Creation Problem (OCP), where tools fails to generate method-call sequences to produce desirable object states.
