A Survey on Effectiveness of Software Testing Techniques and Strategies

Software testing provides an environment to reduce errors, cut maintenance and overall software costs. There are various software development and testing methodologies, testing techniques have emerged over the last few decades to enhance software quality. Software testing is an important activity in the software development life cycle and it is commonly and widely used validation approach in software industry, deployed by programmers and testers. The program with the high complexity cannot be tested completely. More Innovative methods are needed to perform testing as a whole and unit testing with minimum effort and time. Unit testing is mostly done by the developers under a lot of schedule, since the software companies find a compromise between the functionalities, time to market and quality. Thus there is a need for reducing unit testing time by optimizing and automating the process. Test case generation is an error-prone, tedious and time consuming part of unit testing.
