UnitTestDesign.jl: Combinatorial design for unit tests

Abstract

Combinatorial interaction testing is an automated way to generate test cases for unit tests. It’s designed to be a best guess at the fewest unit tests that will give good decision coverage. This article discusses when to use this technique, offers a general approach to using automated test generation for different software testing applications, and shows how to apply it with the UnitTestDesign package in the Julia testing ecosystem.
