Reducing Software Testing Time with Combinatorial Testing and Test Automation

The development of large software systems is a complex and error prone process. Errors may occur at any stage of software development. These errors, sometimes referred to as bugs, can cause great losses in terms of both time and money if not identified and removed as early as possible. Testing a software product is costly, since it takes much time and need to test many combinations of its functions, integrity, performance etc., which can be called as test cases. The company\u27s goal is to reduce the testing time, so that they can save money and deliver the product much faster to the customer. Testing time can be reduced in two main ways, first by reducing number of test cases and second by automating repeatedly testing areas. This paper will discuss fundamentals of testing such as importance and difference of verification and validation, testing throughout the software development life cycle and testing methods, levels and types. Then it will discuss the possibility of reducing the time spent on testing by reducing number of test cases with combinatorial testing and automating repeatedly tested areas with test automation using Selenium tool. Finally it will also shed some light on a real world test automation project with selenium and two integrated develop environments
