Constraint-Guided Test Execution Scheduling: An Experience Report at ABB Robotics
arxiv(2023)
摘要
Automated test execution scheduling is crucial in modern software development
environments, where components are frequently updated with changes that impact
their integration with hardware systems. Building test schedules, which focus
on the right tests and make optimal use of the available resources, both time
and hardware, under consideration of vast requirements on the selection of test
cases and their assignment to certain test execution machines, is a complex
optimization task. Manual solutions are time-consuming and often error-prone.
Furthermore, when software and hardware components and test scripts are
frequently added, removed or updated, static test execution scheduling is no
longer feasible and the motivation for automation taking care of dynamic
changes grows. Since 2012, our work has focused on transferring technology
based on constraint programming for automating the testing of industrial
robotic systems at ABB Robotics. After having successfully transferred
constraint satisfaction models dedicated to test case generation, we present
the results of a project called DynTest whose goal is to automate the
scheduling of test execution from a large test repository, on distinct
industrial robots. This paper reports on our experience and lessons learned for
successfully transferring constraint-based optimization models for test
execution scheduling at ABB Robotics. Our experience underlines the benefits of
a close collaboration between industry and academia for both parties.
