Software testing is an activity which is aimed for evaluating quality of a program and also for improving it, by identifying defects and problems. Software testing strives for achieving its goals (both implicit and explicit) but it does have certain limitations, still testing can be done more effectively if certain established principles are be followed. In spite of having limitations, software testing continues to dominate other verification techniques like static analysis, model checking, and proofs. So it is indispensable to understand the goals, principles and limitations of software testing so that the effectiveness of software testing could be maximized.

From previous year researches, it is concluded that testing is playing a vital role in the development of the software product. As, software testing is a single approach to assure the quality of the software so most of the development efforts are put on the software testing. But software testing is an expensive process and consumes a lot of time. So, testing should be start as early as possible in the development to control the money and time problems. Even, testing should be performed at every step in the software development life cycle (SDLC) which is a structured approach used in the development of the software product. Software testing is a tradeoff between budget, time and quality. Now a day, testing becomes a very important activity in terms of exposure, security, performance and usability. Hence, software testing faces a collection of challenges.

Software Testing is the process of evaluating a software program to ensure that it performs its intended purpose. Software testing verifies the safety, reliability, and correct working of the software. The growing need for quality software makes software testing a crucial stage in Software Development Lifecycle. There are many methods of testing software, however, the choice of method to test a given software remains a major problem in software testing. Although, it is often impossible to find all errors in software, employing right combination of methods will make software testing efficient and successful. Knowing these software testing methods is the key to making right selection. This paper presents a comprehensive study of software testing methods. An explanation of Testing Categories was presented first, followed by Testing Levels (and their comparison), then Testing Techniques (and their comparison). For each Testing Levels and Testing Techniques, examples of some testing type...

The development of large software systems is a complex and error prone process. Faults might occur at any development stage and they must be identified and removed as early as possible to stop their propagation and reduce verification costs. Quality engineers must be involved in the development process since the very early phases to identify required qualities and estimate their impact on the development process. Their tasks span over the whole development cycle and go beyond the product deployment through maintenance and post mortem analysis. Developing and enacting an effective quality process is not a simple task, but it requires that we integrate many quality-related activities with product characteristics, process organization, available resources and skills, and budget constraints. This paper discusses the main characteristics of a good quality process, then surveys the key testing phases and presents modern functional and model-based testing approaches.

Software testing is a process of evaluating the developed software against the actual requirements from the customer. Software development methodology has transformed based on numerous driving factors over decades and so is the software testing methodologies. Software remains inevitable in rapid growth of technologies in various fields like academy, medicine, media, safety, agriculture, robotics, gaming, aviation, national defence etc., In this paper, the existing and emerging trends, techniques, and issues of software testing are discussed based on the technologies.

Software testing is as old as the hills in the history of digital computers. The testing of software is an important means of assessing the software to determine its quality. Since testing typically consumes 40~50% of development efforts, and consumes more effort for systems that require higher levels of reliability, it is a significant part of the software engineering. With the development of Fourth generation languages (4GL), which speeds up the implementation process, the proportion of time devoted to testing increased. As the amount of maintenance and upgrade of existing systems grow, significant amount of testing will also be needed to verify systems after changes are made [12]. Despite advances in formal methods and verification techniques, a system still needs to be tested before it is used. Testing remains the truly effective means to assure the quality of a software system of non-trivial complexity [13], as well as one of the most intricate and least understood areas in software engineering [19]. Testing, an important research area within computer science is likely to become even more important in the future.

Computer software is a major component of an information system (IS) whose reliability is critical to the performance of an organization. The reliability of an IS has four facets people, hardware, software and data. Among these four facets, the reliability of software is a joint responsibility of computer science and information system professionals; the former handles technical software and the latter application software. Regardless of the types of software involved, the reliability of software must be achieved through a continuous effort of planning, analysis, design, programming, testing, installation and maintenance. To quote an old sage, "Quality is built in, not added on." Studies have shown that most of the system errors detected during the testing phase originate in the early analysis phase. 2 Therefore, software testing should start early in the system development process. A system development process today may come in many different forms. Depending on the structure of the intended system, a system development life cycle (SDLC) process 6 or a prototyping process 2,7,13 or a mixture of both 4 can be followed. An SDLC process typically is applied to a system with clear requirements definitions, well structured processing and reporting, and a long and stable life expectancy. On the other hand, a prototyping process is suitable for a system of ambiguous or incomplete requirements with ad hoc reporting capability, or of a transient life span with ever-changing requirements. It may be used along with an SDLC process to shorten the development time required by a project adopting the SDLC process. The scope of this article is to discuss the software testing process and test activities in a large system project following the SDLC approach. The test process and activities discussed herein is complete and rigorous. Its principles can be applied to a project of any size and using any system development approach,. be it an SDLC a prototyping, ware acquisition or a spiral development and enhancement 4 approach.
