Fault Injection Technique for Evaluating Erlang Test Suites

In software testing, fault injection involves injecting abnormalities into software programs. This can then be used to evaluate test suites by checking how well they detect those abnormalities. This study involves finding out what typical faults occur in Erlang programs by analyzing data from Erlang/OTP releases, official Erlang reference manual, Erlang bug reports and other related studies. It will also include proposals of how these faults can be injected into Erlang programs based on our Erlang development experience and knowledge. The method adopted in this study involves the implementation of a fault injection tool which was evaluated on the test suite of Erlang/ OTP R13B array module. This study contributes knowledge to how fault injection can be used to evaluate Erlang test suites. This in summary involves the following (1) injecting non-trivial faults one at a time into a target Erlang program; these are faults that cannot be detected at compile time, by dialyzer or by a test suite and cover information, and (2) evaluating the program test suite by studying if it can identify the injected fault, and if not why

Effects of demographic factors on bank customers' attitudes and intention toward Internet banking adoption in a major developing African country

This study provides an African perspective to the global research and literature on retail customer adoption of Internet banking (IB). It empirically examines the influence of seven demographic variables – age, gender, level of education, marital status, employment status, income level and area of residence – on retail banking customers' behaviours toward IB adoption in a major developing African country – Nigeria. A sample of 500 customers was surveyed, and ANOVA and multiple regression analyses were used in testing the association of the variables with customer attitude and intention toward IB adoption. Although all seven variables were correlated with attitude and intention, only gender, level of education, and employment status showed significant ability to influence Nigerian customers' attitude and intention toward IB adoption. The study therefore concludes that gender, level of education, and employment status are the major demographic affecters of Nigerian banking customers' attitudes to IB adoption
