A tracking system or defect tracking system is a software application that keeps track of reported software bugs in software development projects. It may be regarded as a type of issue tracking system . Many bug tracking systems, such as those used by most open-source software projects, allow end-users to enter bug reports directly. [1]
A software bug is a 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 ). Software bugs have been linked to disasters.
Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement. While it may imply it's a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it doesn't mean functions/methods, modules or classes always correspond to units.
Software testing. Software testing is the act of checking whether software 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. [ 1 ] Software testing can determine the correctness of software for specific scenarios, but cannot ...
In systems engineering, information systems and software engineering, the systems development life cycle ( SDLC ), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. [ 1] The SDLC concept applies to a range of hardware and software configurations, as a ...
A test strategy is an outline that describes the testing approach of the software development cycle. The purpose of a test strategy is to provide a rational deduction from organizational, high-level objectives to actual test activities to meet those objectives from a quality assurance perspective. The creation and documentation of a test ...
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
Distributed operating system. A distributed operating system is system software over a collection of independent software, networked, communicating, and physically separate computational nodes. They handle jobs which are serviced by multiple CPUs. [1] Each individual node holds a specific software subset of the global aggregate operating system.
