Test coverage is an important indicator for unit test quality. Tools such as Clover compute coverage by first instrumenting the code with logging functionality, and then logging which parts are executed during unit test runs. Since computation of test coverage is a dynamic analysis, it presupposes a working installation of the software. In the context of software quality assessment by an independent...
A new method called EPDG-GA which utilizes the edge partitions dominator graph (EPDG) and genetic algorithm (GA) for branch coverage testing is presented in this paper. First, a set of critical branches (CBs) are obtained by analyzing the EPDG of the tested program, while covering all the CBs implies covering all the branches of the control flow graph (CFG). Then, the fitness functions are instrumented...
We propose a novel test coverage analysis technique for object-oriented programs. Our technique consists of three phases: graph construction, instrumentation, and coverage analysis. In the graph construction phase, the source program is converted into a dependence graph-based representation, named Call-based Object-Oriented System Dependence Graph (COSDG). In the instrumentation phase, the source...
