A challenging part of software testing entails the generation of test cases. A good test case should have the quality to cover more features of test objective. The techniques for automatic generation of test cases try to efficiently find a small set of cases that allow an adequacy criterion to be fulfilled, thus reducing the cost of software testing and resulting in more efficient testing of software products. In this paper, the authors introduce an all-around classification framework for automatic test case generation approaches in terms of test type and Algorithm, and represent some test case evaluation approaches. Finally, they illustrate a comparison between different existing techniques.
