### Question:
TaskunLogUtilLoggerImpl implements TaskunLog { ClassNameAndMethodName getClassNameAndMethodName() { StackTraceElement[] stack = (new Throwable()).getStackTrace(); int stackDepth = 0; while (stackDepth < stack.length) { StackTraceElement frame = stack[stackDepth]; if (frame.getClassName().equals("java.util.logging.Logger")) { break; } stackDepth++; } while (stackDepth < stack.length) { StackTraceElement frame = stack[stackDepth]; if (!frame.getClassName().equals("java.util.logging.Logger")) { return new ClassNameAndMethodName(frame.getClassName(), frame.getMethodName()); } stackDepth++; } return new ClassNameAndMethodName("", ""); } TaskunLogUtilLoggerImpl();  TaskunLogUtilLoggerImpl(Class<?> clazz);  TaskunLogUtilLoggerImpl(String name); @Override void debug(String message); @Override void debug(String message, Throwable t); @Override void info(String message); @Override void info(String message, Throwable t); @Override void warn(String message); @Override void warn(String message, Throwable t); @Override void error(String message); @Override void error(String message, Throwable t);  }### Answer:
@Test public void getClassNameAndMethodName_A$() throws Exception { TaskunLogUtilLoggerImpl.ClassNameAndMethodName actual = new TaskunLogUtilLoggerImpl().getClassNameAndMethodName(); assertEquals("", actual.className); assertEquals("", actual.methodName); }
