How to print current executing JUnit test method while running all tests in a class or suite using ANT?

Question

I have a set of JUnit Test Cases and I execute them from ANT using the junit task. While executing the tests, in the console I get to see only which test case (i.e. Java cla

Unfortunately, there is no good way to hook into JUnit. For a framework that was developed with TDD, it's astonishingly hostile.

Use a @Rule instead:

import org.junit.rules.TestWatcher;
import org.junit.runner.Description;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

/**
 * Log the currently running test.
 * 
 * 
Typical usage:
 * 
 * 
{@code @Rule public LogTestName logTestName = new LogTestName();}
 *
 * 
See also:
 * 
{@link org.junit.Rule}
 * 
{@link org.junit.rules.TestWatcher}
 */
public class LogTestName extends TestWatcher {

    private final static Logger log = LoggerFactory.getLogger( "junit.logTestName" );

    @Override
    protected void starting( Description description ) {
        log.debug( "Test {}", description.getMethodName() );
    }

}

Notes:

I'm using a static logger. That makes the code execute faster but my main reason is that logging test names is a cross-cutting concern: I would like to enable/disable this logging in a central place instead of configuring it for each test class.

Another reason is that I have tools which process the build output and those are easier to configure for a fixed pattern :-)

If you don't want this, then just get the logger for description.getTestClass().
