A reliability growth model is a mathematical model of how software reliability improves as errors are detected and repaired. A reliability growth model can be used to predict when (or…
Classification of failures of software products into five different types is as follows:Transient– Transient failures occur only for certain input values while invoking a function of the system.Permanent– Permanent failures…
The reasons why software reliability is difficult to measure can be summarized as follows: The reliability improvement due to fixing a single bug depends on where the bug is located in…
Software reverse engineering is the process of recovering the design and the requirements specification of a product from an analysis of its code. The purpose of reverse engineering is to…
Software maintenance work typically is much more expensive than what it should be and takes more time than required. In software organizations, maintenance work is mostly carried out using ad…
Types of software maintenance. Corrective: Corrective maintenance of a software product is necessary to rectify the bugs observed while the system is in use. Adaptive: A software product might need maintenance when the…
Error seed can be used to estimate the number of residual errors in a system. Error seeding, as the name implies, seeds the code with some known errors. In other…
Performance testing is carried out to check whether the system needs the non-functional requirements identified in the SRS document. There are several types of performance testing. Among of them nine…
There are essentially three main kinds of system testing:Alpha Testing. Alpha testing refers to the system testing carried out by the test team within the developing organization. Beta testing. Beta testing is the…
