This paper examines how ISO/IEC 9126-1 and ISO/IEC 25010 quality models can be applied to software testing products in industrial environment. We present a set of code smells for test systems written in TTCN-3 and their categorization according to quality model standards. We demonstrate our measurements on industrial and ETSI projects, and provide a method for estimating their effects on produc...

Measuring high level quality attributes of operation-critical IT systems is essential for keeping the maintainability costs under control. International standards and recommendations, like ISO/IEC 9126, give some guidelines regarding the different quality characteristics to be assessed, however, they do not define unambiguously their relationship to the low level quality attributes. The vast ma...

In this paper, we study the software reliability measurement method of reliability testing metrics. Software reliability is very important. But, it is very difficult to test for software reliability measurement. So we describes the software reliability metrics for ISO/IEC 9126, and we introduce GammaLomax software reliability model for multiple error debugging. And we calculate the software rel...

As software complexity grows and clients demand higher quality software, quality requirements can no longer be considered to be of secondary importance. Thus eliciting, specifying, prioritising and validating quality requirements is a pre-requisite to the development of effective and efficient information systems. Despite the critical importance of quality requirements, there is a considerable ...
