A New Method for Comparative Study of Three Software Testing Techniques

Software testing is considered as one of the key phases in the software-development life cycle (SDLC). The main objective of software testing is to detect the faults either through manual testing or with automated testing approach. The most commonly adopted software testing approach in industries is test case based testing (TCBT) which is usually done manually. TCBT is mainly used by the software testers to formalize and guide their testing activities and set theoretical principals for testing. Model based testing (MBT) is widely used automation software testing technique to generate and execute the tests. Black-box testing, on the other hand is a method of software testing that examines the functionality of an application based on the specifications. All the three techniques are showing their prominence in real time with some pros and cons. However, there is no formal comparison available among these three techniques. The main objective of this paper is to find out the difference in test cases in TCBT, MBT and Black-box in terms of providing better test coverage (Statement, Branch and Path), requirement, traceability, cost and time.
