    val = (Boolean) m.invoke(null);
    Assert.assertTrue(val);
}

Example 4 with EvoClassLoader

use of org.evosuite.runtime.instrumentation.EvoClassLoader in project evosuite by EvoSuite.

the class EvoRunner method getFromEvoSuiteClassloader.

private static Class<?> getFromEvoSuiteClassloader(Class<?> clazz) throws InitializationError {
    try {
        /*
	    	 *  properties like REPLACE_CALLS will be set directly in the JUnit files
	    	 */
        // LoggingUtils.loadLogbackForEvoSuite();
        /*
	    	 * This approach does throw away all the possible instrumentation done on the input clazz,
	    	 * eg code coverage of Emma, Cobertura, Javalanche, etc.
	    	 * Furthermore, if the classloader used to load EvoRunner is not the same as CUT,
	    	 * then loading CUTs will fail (this does happen in "mvn test")
	    	 */
        EvoClassLoader classLoader = new EvoClassLoader();
        classLoader.skipInstrumentation(clazz.getName());
        Thread.currentThread().setContextClassLoader(classLoader);
