Sample test file which fails

Hi

I came across this interesting bug. Looks like in the UI but could be deeper.

If any System.out.println("<message>") has a <message> which starts with the word "Running" then the UI shows "No tests executed (0.0s)" after the tests are run.

I saw the issue first on Netbeans 7.4. I thought i might be running into some version issues so i upgraded to 8.0 but it happens in 8.0 too. I saw it on my Maven web project + TestNG combination but may exist for older versions and other project type + test framework combinations too.


Here are the steps to reproduce on 8.0.

1) Create a new Maven Web project.


2) Add TestNG as a dependency. I added the following lines in the pom.xml dependency section

<dependency>
      <groupId>org.testng</groupId>
      <artifactId>testng</artifactId>
      <version>6.8.8</version>
      <scope>test</scope>
</dependency>


3) Right click on the project Name > New > TestNG Test Case.
(ofcourse, this above can be done through the New.. dialog too). 
This will create a skeleton test.

4) Add the following two methods in the test.


//////// CODE  /////////////
    @Test
    public void hello1() {
        assertEquals(true, true);
        
        System.out.println("A");
        for (int i = 0; i < 2; i++) {
            
            System.out.println("Running some test case" ); // fails
//            System.out.println("some test case"); // works
//            System.out.println(" Running some test case" ); // works - notice the space at start
        }
        
        assertEquals(true, false);

    }
    
    @Test
    public void hello2() {
        assertEquals(true, true);
    }

//////  END CODE ///////////

5) Now right click in the editor > Test File

6) The Test Results Window shows "No tests executed" - BUG!!

7) Now comment the //fails System.out.println() line above and uncomment one of the // works lines and repeat step 5.

8) Now the Test Results window shows the proper GUI results.

9) I am attaching my sample test file for reference. The purpose of hello2() test method is just to show that the error prohibits all the other methods' results to also not show up in addition to the method with the bug causing output statement.
