JUnit 5 Samples

Welcome to JUnit 5 Samples, a collection of sample applications and extensions using JUnit Jupiter, JUnit Vintage, and the JUnit Platform on various build systems.

CI builds for sample projects are performed by GitHub Actions. Using JDK 11+'s jshell tool, you may build all samples via the build-all-samples.jsh script.
