Abstract
Ensuring the security of the software has raised concerns from the research community which triggered numerous approaches that tend to eliminate it. The process of ensuring the security of software includes the introduction of processes in the Software Development Life Cycle where one of them is testing after the software is developed. Manually testing software for security is a labor-intensive task. Therefore, it is required to automate the process of testing by generating test cases by automated techniques. In this paper, we review various software security test case generation approaches and techniques. We try to explore and classify the most eminent techniques for test case generation. The techniques are summarized and presented briefly to covers all researches work that has been done in the targeted classification. Moreover, this paper aims to depict the sound of security in the current state of the art of test case generation. The findings are summarized and discussed where the opportunities and challenges are revealed narratively. Although the paper intends to provide a comprehensive view of the research in test case generation, there was a noticeable lack in the test case generation from the security perspectives.
