Description

I am not sure if this is a bug or a configuration issue, but I face a weird behaviour. When running a test that print to stdout, the "Test Results" pane text output area remains empty if the test result is success. On the contrary, when a test is failing the stdout String text is printed normally in "Test Results" pane text output area.

A simple class that has a method, which prints a message

public class HelloWorld {

    public String printHelloMessage() {
        return "Hello";
    }
}

Another simple test class

public class HelloWorldTest {  

    @Test
    public void testPrintHelloMessage() {
        System.out.println("Print out a Message");
        HelloWorld instance = new HelloWorld();
        String expResult = "Hello";
        String result = instance.printHelloMessage();
        assertEquals(expResult, result);
    }
}
