Software testingChecking software against expectationsTestingCup – Polish Championship in Software Testing, Katowice, May 2016Software testing is the act of checking whether software meets its intended objectives and satisfies expectations. Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor or any other stakeholder.Unit testingUnit testing, also known as component or module testing, is a form of software testing by which isolated source code is tested to validate expected behavior. Unit testing describes tests that are run at the unit-level to contrast testing at the integration or system level.
Software bugA software bug is a defect (bug) in computer software. A computer program with many or serious bugs may be described as buggy. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing).
SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.
Patch (computing)A patch is data for modifying an existing software resource such as a program or a file, often to fix bugs and security vulnerabilities. To patch is also the process of applying the data to the existing resource. Patching a system involves applying a patch. A patch may be created to improve functionality, usability, or performance.Software developmentSoftware development is the process of designing, creating, testing, and maintaining software applications to meet specific user needs or business objectives. The process is more encompassing than programming, writing code, because it includes conceiving the goal, evaluating feasibility, analyzing requirements, design, testing and release.Software designSoftware design is the process of conceptualizing how a software system will work before it is implemented or modified. Software design also refers to the direct result of the design process – the concepts of how the software will work which may be formally documented or may be maintained less formally, including via oral tradition.
White-box testingWhite-box testing (also known as clear box testing, glass box testing, transparent box testing, and structural testing) is a method of software testing that tests internal structures or workings of an application, as opposed to its functionality (i.e. black-box testing). In white-box testing, an internal perspective of the system is used to design test cases. The tester chooses inputs to exercise paths through the code and determine the expected outputs.
Requirements analysisEngineering process A systems engineering perspective on requirements analysis In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating, and managing software or system requirements.Software distributionSoftware distribution is the process of delivering software and it is the asset that contains the data used in the process.
Mastering (audio)Mastering is a form of audio post-production which is the process of preparing and transferring recorded audio from a source containing the final mix to a data storage device called a master recording, the source from which all copies will be produced (via methods such as pressing, duplication or replication).
Operating systemAn operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other resources.*As an Amazon Associate I earn from qualifying purchases.
