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.
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 ...
Concurrent testing. Research [1] and literature [2] on concurrency testing and concurrent testing typically focuses on testing software and systems that use concurrent computing. The purpose is, as with most software testing, to understand the behaviour and performance of a software system that uses concurrent computing, particularly assessing ...
Verification is a Review Process. Depending on the scope of tests, we can categorize them in three families: The aim of software dynamic verification is to find the errors introduced by an activity (for example, having a medical software to analyze bio-chemical data); or by the repetitive performance of one or more activities (such as a stress ...
Bug (engineering) In engineering, a bug is a design defect in an engineered system that causes an undesired result. Although used exclusively to describe a technical issue, bug is a non-technical term; applicable without technical understanding of the system. The term bug applies exclusively to a system that is (human) designed; not to a ...
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).
These techniques worked by adding a number of known faults to a software system for the purpose of monitoring the rate of detection and removal. This assumed that it is possible to estimate the number of remaining faults in a software system still to be detected by a particular test methodology. Bebugging is a type of fault injection.

Software performance testing. In software quality assurance, performance testing is in general a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. [1] It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as ...
