How do I write a Junit test for my main method in the class

Hi,
How do I write a Junit test for my main method in the class. It is the only method in the class and as usual returns void. I can't see any side effect also happenning here which will help me test the result.

Thanks,
Sandeep

But the main method does something, right? :-)

I'd restructure the code so that all the functional code moves out of the main method into instance methods that return meaningful results. So instead of

public static void main (String[] args) {
    // do something here
}

you'd have

public static void main (String[] args) {
    MyClass myObject = new MyClass();
    myObject.doSomething();
}
 
public <return type> doSomething() {
    // do something here
}
