CAGEN: A fast combinatorial test generation tool with support for constraints and higher-index arrays

In recent years, combinatorial testing methods have been successfully applied to test systems with a larger number of input parameters. Generating combinatorial test sets for such complex systems is a challenging task as it requires a lot of time and computing power. To tackle that issue, high performance tools are required. In this work, we present the combinatorial test set generation tool CAgen. It is capable of generating combinatorial test sets significantly faster than other state-of-the-art tools, such as ACTS, and contains various features such as constraint handling and higher-index arrays. It is highly compatible with other combinatorial testing tools and is available as CLI and Web-GUI. CAgen aims to make combinatorial testing more efficient and more accessible and user-friendly.
