Abstract

Testing techniques refer to different methods or ways of testing particular features of a computer program, system or product. Presently there are so many different software testing techniques that we can use. Whether we decide to automate or just execute tests manually, there is a selection of testing techniques to choose from. We have to make sure that we select technique(s) that will help to ensure the most efficient and effective testing of the system. The fundamental problem in software testing thus throws an open question, as to what would be the techniques that we should adopt for an efficient and effective testing. Thus, the selection of right testing techniques at the right time for right problem will make the software testing efficient and effective. In this paper we discuss how should testing techniques be compared with one another and why do we face a problem in making appropriate testing technique selection.

Abstract

File system operations include data operations and metadata operations. Data operations act upon actual user data while metadata operations modify the structure of the file system, like creating, deleting, or renaming files, directories, etc. During a metadata operation, the system must ensure that data are written to disk in such a way that the file system can be recovered to a consistent state after a system crash. In this paper we look at some most notable techniques which ensure reliability of disk file systems against system crashes and failures.

Abstract

Software Reliability is an important component of software quality. A number of software reliability models have been proposed since 1970s, but there is no single model that can be used in all the situations. To reduce the risk, it is better to experiment with the model of the system rather than with the system itself. Simulation, offers an attractive alternative to analytical models as it describes a system being characterized in terms of its artifacts, events, interrelationships and interactions in such a way that one may perform experiments on the model, rather than on the system itself. Simulation strives for achieving its goals but it does have certain limitations. This research paper focuses on the goals and limitations of using simulation in software reliability.

Keywords

Abstract

Testing remains the truly effective means to assure the quality of a software system of nontrivial complexity. An important aspect of test planning is measuring test effectiveness. To make testing more successful we need to choose effective testing techniques. To compare testing techniques we need to place software testing techniques on a measurement scale which can define the relative merits of the existing testing techniques, but due to differences in software’s and its allied parameters this task seems to be complex, if not impossible.

Abstract

FAT file system is the most primitive, compatible and simple file system which still sustains in this era on digital devices, such as mini MP3 players, smart phones, and digital cameras. This file system is supported by almost all operating systems because of its simplicity and legacy. This paper presents review of the basic design technique, constraints and formulas of the most important and building block data structure of FAT32 file system; the FAT data structure.
