System testing can detect defects in the system as a whole. [citation needed] [1] System testing can verify the design, the behavior and even the believed expectations of the customer. It is also intended to test up to and beyond the bounds of specified software and hardware requirements. [citation needed]
ISO/IEC/IEEE 29119 Software and systems engineering -- Software testing [1] is a series of five international standards for software testing.First developed in 2007 [2] and released in 2013, the standard "defines vocabulary, processes, documentation, techniques, and a process assessment model for testing that can be used within any software development lifecycle."
Software testing can also be performed by non-dedicated software testers. In the 1980s, the term software tester started to be used to denote a separate profession. Notable software testing roles and titles include: [65] test manager, test lead, test analyst, test designer, tester, automation developer, and test administrator. [66]
Software rot (bit rot, code rot, software erosion, software decay, or software entropy) is the degradation, deterioration, or loss of the use or performance of software over time. From a software user experience perspective, it is operating environmental evolution inclusive of hardware.
In addition to various implementations of static analysis, such as flow analysis, and unit testing, development testing also includes peer code review as a primary quality activity. Code review is widely considered one of the most effective defect detection and prevention methods in software development. [10]
Software reliability testing is being used as a tool to help assess these software engineering technologies. [9] To improve the performance of software product and software development process, a thorough assessment of reliability is required. Testing software reliability is important because it is of great use for software managers and ...
The goal of continuous testing is to provide fast and continuous feedback regarding the level of business risk in the latest build or release candidate. [2] This information can then be used to determine if the software is ready to progress through the delivery pipeline at any given time.
Software diagnosis—in contrast to many approaches in software engineering—does not assume that developer capabilities, development methods, programming or modeling languages are right or wrong (or better or worse compared to each other): Software diagnosis aims at giving insight into a given software system and its status regardless of the ...
