Interesting Quotes from AMD Canada Event

Quote

On March 7th of last year I attended an OCE event called the “AMD HSA and Heterogeneous Computing Research Showcase.” I recently came across my notes from the event and I thought a few quotes from the keynote speaker, Phil Rogers from AMD Canada,  were worth sharing.

Phil Rogers on AMD’s commitment to open industry standards:

“open standards always win over time.” 

Phil Rogers on programming with threads:

“An expert can get two threads right. An expert can sometimes get three threads right… but cannot get all of the test cases right… doesn’t scale (to 100s of threads).”

Predicting Mutation Scores

Last week my MSc student, Kevin Jalbert, presented his early thesis results at the Workshop on Realizing Artificial Intelligence Synergies in Software Engineering (RAISE 2012). The workshop took place in Zurich Switzerland and was colocated with ICSE 2012. The title of the presentation (and the paper that appears in the proceedings) was “Predicting Mutation Score Using Source Code and Test Suite Metrics.” The paper was awarded the Best Paper Award at the workshop.

Mutation testing can be used to evaluate the effectiveness of test suites and can also be used as an oracle during the creation or improvement of test suites. Mutation testing works by creating many versions of a program each with a single syntactic fault. These program versions are created using mutation operators which are based on an existing fault taxonomy (i.e., a set of known fault types that we are trying to find during testing). One mutation operator, Relational Operator Replacement (ROR), could create a new mutant version of the program in which one of the instance of a relational operator (e.g., <) is replaced with a different operator. For example, line 3 of the following Java source  code: Continue reading

Software Testing Tools for Concurrency

As the use of concurrency in software increases there are more software testing tools being developed in both industry an academia. Below is a fairly comprehensive list of tools (mainly for Java):
  • ConTest – IBM concurrent testing tool that inserts random delays into Java bytecode
  • ConAn – a thread testing tool for Java
  • CHESS – a Microsoft tool for concurrent testing in Visual Studio
  • CalFuzzer – an active testing framework
  • ConMAn – mutation testing tool for concurrent programs written in Java
  • Continue reading
