# zunit: Zero-Dependency Java 25 Test Runner

zunit is a zero-dependency, single-file Java 25 Script test runner.
  It discovers *Test.java source files and runs each directly via java --source 25.
  No compilation step, no JUnit, no build tool required — just run zunit.
A GreeterTest.java example:


void main() {
    var greeting = Greeter.greet("World");
    assert Objects.equals("Hello, World!", greeting) : "expected 'Hello, World!' but got: " + greeting;
}



Each test is a self-contained Java source script with a void main() method.
  Any thrown exception or non-zero exit code indicates test failure.
  Each test gets its own JVM — full execution isolation with zero shared state.
Run it with:

zunit to auto-detect and run all tests, 
zunit -cp:zbo/app.jar for an explicit classpath
zb && zunit to build with zb first.
