With the success of agile methodologies, Testing has become a common and important activity in the development of software projects. Large and automated test-suites ensure that the system is behaving as expected. Moreover, tests also offer a live documentation for the code and can be used to understand foreign code. However, as the system evolves, tests need to evolve as well to keep up with th...

In the context of test driven development, tests specify the behavior of a program before the code that implements it, is actually written. In addition, they are used as main source of documentation in XP projects, together with the program code. However, tests alone describe the properties of a program only in terms of examples and thus are not sufficient to completely describe the behavior of...

In this study, the components important for testing work and organisational test process are identified and analysed. This work focuses on the testing activities in real-life software organisations, identifying the important test process components, observing testing work in practice, and analysing how the organisational test process could be developed. Software professionals from 14 different ...

Background: Sand production is an important factor affecting reservoir exploitation. Excessive sand production affects the oil well life, causes the damage to the oil recovery device and brings serious hidden danger in the process of safety production. Objective: This paper presents a sand content computation model for the crude oil, which uses the power of sand production and Parseval theorem,...

Emerging ontology authoring methods to add knowledge to an ontology focus on ameliorating the validation bottleneck. The verification of the newly added axiom is still one of trying and seeing what the reasoner says, because a systematic testbed for ontology authoring is missing. We sought to address this by introducing the approach of test-driven development for ontology authoring. We specify ...

Test-Driven Development (TDD) is one of the core programming practices of XP. However, developing database access code testdriven is often difficult, if not impossible. This paper presents a practical solution to this problem, making use of local development databases for testing and Open Source tools for schema migration and test data management. The examples are outlined in Java, but the basi...

OBJECTIVES Despite vast amounts of research examining the influence of hearing loss on speech perception, comparatively little is known about its influence on music perception. No standardized test exists to quantify music perception of hearing-impaired (HI) persons in a clinically practical manner. This study presents the Adaptive Music Perception (AMP) test as a tool to assess important aspec...

Impending development of a blood test for AIDS has paved the way for an epidemiological study by the National Heart, Lung and Blood Institute. Blood samples from 200,000 presumably healthy donors will soon be drawn and stored, to be screened when the test becomes available. Donors and recipients of blood which tests AIDS-positive will then be followed to see if AIDS develops. The study raise...
