Systematic Testing of Software with Structurally Complex Inputs

Darko MarinovAssistant ProfessorDepartment of Computer Science, University of Illinois at Urbana-Champaign

Modern software pervasively uses structurally complex data, for example web-traversal code operates on graphs that encode web pages, and IDEs manipulate program representations such as abstract syntax trees. The standard approach to generating test suites for such software, manual generation of the inputs in the suite, is tedious and error-prone. This talk presents a new approach that automates the generation of suites with structurally complex test inputs. Our approach is based on test abstractions which provide a high-level description of desired test suites.
Developers do not need to manually write large suites of individual tests but instead write test abstractions from which tools automatically generate individual tests. This approach has helped developers in both academia and industry to discover errors in several real applications. This talk focuses on two recent projects, speeding up testing through parallelization (our experiments on up to 1024 machines on the Google's infrastructure show significant speedups, up to 543.55 times) and using imperative test abstractions (in particular to test parts of Eclipse and NetBeans, two popular IDEs, in which our approach discovered 45 new errors).
