in the software development process, testing is one of the most human intensive steps. many researchers try to automate test case generation to reduce the manual labor of this step. negative selection is a famous algorithm in the field of artificial immune system (ais) and many different applications has been developed using its idea. in this paper we have designed a new algorithm based on nega...

Many reliability prediction techniques require an estimate for the number of residual faults. In this paper, a new theory is developed for using test coverage to estimate the number of residual faults. This theory is applied to a specific example with known faults and the results agree well with the theory. The theory is used to justify the use of linear extrapolation to estimate residual fault...

This article presents a controlled experiment that compares the behavior of the testing techniques Statement Coverage and All Uses. The design of this experiment is typical for a factor with two alternatives. A total of 14 subjects carry out tests on a single program. The results indicate that there is enough statistical evidence to state that the cost of executing All Uses is higher than that ...

This paper describes SimpleNLG for German, a surface realisation engine for German based on SimpleNLG (Gatt and Reiter, 2009). Several features of the syntax of German and their implementation within the current framework are discussed, with a special focus on word order phenomena. Grammatical coverage of the system is demonstrated by means of selected examples.

In TREC 2003, IRIT improved the strategy that was introduced in TREC 2002. A sentence is considered as relevant if it matches the topic with a certain level of coverage. This coverage depends on the category of terms used in the texts. Different types of terms have been defined: highly relevant, scarcely relevant, nonrelevant and highly non-relevant. With regard to the novelty part, a sentence ...

When testing software, testers rarely use only one technique to generate tests that, they hope, will fulfill their testing criteria. Malaiya showed that testers switch strategies when testing yield saturates. We present and evaluate a stopping rule that can be used to determine when it is time to switch to a different testing technique, because the current one is not likely to increase criteria...

Among other things, the modern game of football is characterised by pronounced group and team-oriented tactical abilities. Of particular importance is thereby zone defence or zone coverage, which is used by almost all teams playing at an elevated level of performance. In contrast to man-marking, this more efficient form of organisation is very difficult to convey, as attention must at any given...

This survey tries to give an account of what type of trends exist today in software reuse and testing. The focus was to try to find out how developers use different tools today and what tools are lacking, especially in the field of reuse and testing. The population came from different types of communities and organizations, to better give us a generalized picture of today’s developers. We found...

Students invariably ask the question \How large does n have to be for Z and t intervals to give appropriate coverage probabilities?" In this article we review the role of p 1 (X)= p n, where p 1 (X) is the skewness coeecient of the random sample, in the answer to this question. We also comment on the opposite eeect that p 1 (X) has on the behavior of t intervals compared to Z intervals. Finally...
