Junit5 is around the corner, currently they are on milestone 5. The integration with Intellij IDEA is already working.
However sometimes you just want to run stuff from the console without going through a maven or gradle runner.
I had some problems solving this on my part so here's a simple setup for a project which doesn't have any external dependencies.
Standing in my project directory I issue the following command:
java -jar ~/opt/junit5-console-runner.jar --class-path target/test-classes:target/classes --scan-class-path
So you add the classpath and the you scan it so that the console launcher can find your tests.
You can download the console launcher [here](https://repo1.maven.org/maven2/org/junit/platform/junit-platform-console-standalone/" target="_blank)
