Abstract
Many scientific-software projects test their codes inadequately, or not at
all. Despite its well-known benefits, adopting routine testing is often not
easy. Development teams may have doubts about establishing effective test
procedures, writing test software, or handling the ever-growing complexity of
test cases. They may need to run (and test) on restrictive HPC platforms. They
almost certainly face time and budget pressures that can keep testing
languishing near the bottom of their to-do lists. This paper presents DDTS, a
framework for building test suite applications, designed to fit
scientific-software projects' requirements. DDTS aims to simplify introduction
of rigorous testing, and to ease growing pains as needs mature. It decomposes
the testing problem into practical, intuitive phases; makes configuration and
extension easy; is portable and suitable to HPC platforms; and exploits
parallelism. DDTS is currently used for automated regression and developer
pre-commit testing for several scientific-software projects with disparate
testing requirements.
