Usage

From source file:org.mule.tck.junit4.AbstractMuleTestCase.java

/**
 * Reads the mule-exclusion file for the current test class and
 * @param test/*  w ww .  j  av  a 2s.  c o m*/
 */

    boolean result = false;

    final String testName = test.getClass().getName();

        // use that to find the correct resource. Works fine everywhere,
        // regardless of classloaders. See MULE-2414
        URL classUrl = ClassUtils.getClassPathRoot(test.getClass());
