Good Things Come In Threes: Improving Search-based Crash Reproduction With Helper Objectives

Writing a test case reproducing a reported software crash is a common practice to identify the root cause of an anomaly in the software under test. However, this task is usually labor-intensive and time-taking. Hence, evolutionary intelligence …

Java Unit Testing Tool Competition - Eighth Round

We report on the results of the eighth edition of the Java unit testing tool competition. This year, two tools, EvoSuite and Randoop, were executed on a benchmark with (i) new classes under test, selected from open-source software projects, and (ii) …

Crash Reproduction Using Helper Objectives

Evolutionary-based crash reproduction techniques aid developers in their debugging practices by generating a test case that reproduces a crash given its stack trace. In these techniques, the search process is typically guided by a single search …

Java Unit Testing Tool Competition - Eighth Round

We report on the results of the eighth edition of the Java unit testing tool competition. This year, two tools, EvoSuite and Randoop, were executed on a benchmark with (i) new classes under test, selected from open-source software projects, and (ii) …

Search-based Crash Reproduction using Behavioral Model Seeding

Search-based crash reproduction approaches assist developers during debugging by generating a test case, which reproduces a crash given its stack trace. One of the fundamental steps of this approach is creating objects needed to trigger the crash. …

A benchmark-based evaluation of search-based crash reproduction

Crash reproduction approaches help developers during debugging by generating a test case that reproduces a given crash. Several solutions have been proposed to automate this task. However, the proposed solutions have been evaluated on a limited …

Effective and efficient API misuse detection via exception propagation and search-based testing

Application Programming Interfaces (APIs) typically come with (implicit) usage constraints. The violations of these constraints (API misuses) can lead to software crashes. Even though there are several tools that can detect API misuses, most of them …

Java Unit Testing Tool Competition - Seventh Round

Towards Automated Test Case Generation Maturity

This short paper reports our observations after six editions of the JUnitContest that benchmarks automated unit test generation tools for Java programs. We discuss our experience and depict the current state-of-the-art and identify potential future …
