No junit results (pass OR fail) displayed in terminal

I'm running the demo in:

https://github.com/junit-team/junit4/wiki/Getting-started

I copied Calculator and CalculatorTest exactly as displayed in the page. Compiling failed though:

D:\workspace\junit-example>java -cp d:\junit\latest\junit.jar;. CalculatorTest
Error: Main method not found in class CalculatorTest, please define the main method as:
   public static void main(String[] args)

So I created this file:

public class Runner {

    public Runner() {

    }

    public static void main(String[] args) {

        CalculatorTest c = new CalculatorTest();
        c.evaluatesExpression();
    }

}

The problem is, even though everything compiles and runs (see output below), there isn't any output from JUnit. What is needed to see the result of the test?

D:\workspace\junit-example>javac -cp d:\junit\latest\junit.jar;. *.java

D:\workspace\junit-example>java -cp d:\junit\latest\junit.jar;. Runner

D:\workspace\junit-example>

You don't need your Runner class. Instead, when you run your program, specify org.junit.runner.JUnitCore as the class to run, not CalculatorTest. That way, JUnit will run the test. It's mentioned further down on the page you linked to, under "Run the test."

java -cp .;junit-4.XX.jar;hamcrest-core-1.3.jar org.junit.runner.JUnitCore CalculatorTest

You are running it in a wrong way. You do not need Runner class at all. Also you need to run jUnit runner class and pass class with test methods as a parameter. This is mentioned in that tutorial:

java -cp .;junit-4.XX.jar;hamcrest-core-1.3.jar org.junit.runner.JUnitCore CalculatorTest
