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 determine correctness for all scenarios. [2] [3] It cannot find all bugs.
Software testability is the degree to which a software artifact (e.g. a software system, module, requirement, or design document) supports testing in a given test context. If the testability of an artifact is high, then finding faults in the system (if any) by means of testing is easier. Formally, some systems are testable, and some are not.
Test design is one of the most important prerequisites of software quality. Good test design supports: defining and improving quality related processes and procedures (quality assurance); evaluating the quality of the product with regards to customer expectations and needs (quality control); finding defects in the product (software testing).
The quality model presented in the first part of the standard, ISO/IEC 9126-1, [2] classifies software quality in a structured set of characteristics and sub-characteristics as follows: Functionality - "A set of attributes that bear on the existence of a set of functions and their specified properties. The functions are those that satisfy ...
Software quality is the "capability of a software product to conform to requirements." [36] [37] while for others it can be synonymous with customer- or value-creation [38] [39] or even defect level. [40]
Software testing is an empirical, technical investigation conducted to provide stakeholders with information about the quality of the software under test. [ 1 ] [ 6 ] When described separately from construction, testing typically is performed by test engineers or quality assurance instead of the programmers who wrote it.
Smoke testing is also done by testers before accepting a build for further testing. Microsoft claims that after code reviews, "smoke testing is the most cost-effective method for identifying and fixing defects in software". [10] One can perform smoke tests either manually or using an automated tool. In the case of automated tools, the process ...
Software reliability testing is a field of software-testing that relates to testing a software's ability to function, given environmental conditions, for a particular amount of time. Software reliability testing helps discover many problems in the software design and functionality.
