Software Testing Tools

Software testing refers to the process adopted to gauge the quality of any computer software which is developed. The term quality is used here to take account of topics such as correctness, security and completeness. But the term can also refer to other technical requirements which have been explained by the International Organization for Standardization (ISO) under ISO 9126. It includes various other aspects like reliability, capability, efficiency, maintainability, portability, usability and compatibility. Hence, software testing with the use of software testing tools can be defined as a procedure of technical examination, usually performed for the stakeholders, to reveal information on the quality of the product in relation to the context in which the software is going to be used. There are many automated software testing tools for software testing, but what can be called as an effective testing is a process of examination, and not just simple following of written procedures and algorithms. Software can be tested manually, but the number of variations in the tests becomes so large with even medium sized software, that it becomes virtually impossible to complete even a moderate test which covers a reasonable number of action paths that the software may take at some point of its life. So, manual testing is not feasible in most of the cases. With manual testing ruled out, the only other option is the automated testing with the help of various tools for software testing. It means that we use one software to analyze and another software to test it. This genre of software which is used to test other software is known as the software testing tools. Software testing can also be seen as a query session with the software! The questions are equivalent to the operations that are attempted by various types of software testing tools on the software under consideration, and the latter answers them by reacting to the operations. The type of test required on software i.e. the number of quality attributes that actually need checking to determine the reliability of the software, is dependent on the area the software is developed for. The software for real-time applications requires more error handling features; whereas the database software requires security. So, software testing tools are designed as per the application of the software that it is required to be tested. There are a large number of companies which develop customized testing tools for their clients. Generic software testing tools like security test tools, functional test tools, performance test tools, database test tools, bug tracking tools, communication test tools etc. are also available. The testing tools developed specifically for a kind of software are actually a combination of these generic tools. Previously, software testing tools came into picture only after the software was developed completely. But nowadays, they are an inherent part of the software development process. At every stage of the development, the software is tested for bugs and errors. This makes the process of software development more efficient and on the whole, less time consuming.
