The teaching of programming is a difficult task, and the quality of learning obtained by the students is influenced, among other factors, by the support they receive as they solve problems. To generate hints that help students to fix the mistakes, various strategies have been implemented, primarily focused on finding differences in the obtained and expected outputs, as well as providing information from the static analysis. A method for generating hints, that besides using the above techniques includes performing dynamic analysis, supported in a specification of the inputs and outputs of the problems that allows the system to reason in terms of data types, range, distribution and correspondence between input-output pairs are presented. It was also conducted a study that has demonstrated how the developed method positively influences the number of attempts needed by the students to solve correctly the given exercises.

This reflexion paper aims at discussing a number of issues that typically arise when performing empirical studies with software testing techniques. Though some problems are general to all empirical disciplines, software testing studies face a number of specific challenges. Some of the main ones are discussed below. [ABSTRACT FROM AUTHOR]

Medical devices that utilize computer software are becoming common place in today's health care environment. Device failures can have life threatening consequences. The medical device approval process issued by the FDA should enhance the software testing requirements. In this paper we suggest that Failure Mode Effect Analysis (FEMA) should be a standard component in the testing of software in medical devices that can have life threatening consequences.
