### Question:
LoggerImpl implements Logger { @Override public void debug(final CharSequence message, final Object ... args) { log(clazz, Severity.DEBUG, message, null, args); } private  LoggerImpl(final Class<?> clazz); static LoggerImpl get(final Class<?> clazz); @Override void error(final CharSequence message); @Override void error(final CharSequence message, final Throwable throwable); @Override void error(final CharSequence message, final Object arg0, final Throwable throwable); @Override void error(final CharSequence message, final Object arg0, final Object arg1,
                    final Throwable throwable); @Override void error(final CharSequence message, final Object arg0, final Object arg1,
                    final Object arg2, final Throwable throwable); @Override void error(final CharSequence message, final Object arg0, final Object arg1,
                    final Object arg2, final Object arg3, final Throwable throwable); @Override void error(final CharSequence message, final Object arg0, final Object arg1,
                    final Object arg2, final Object arg3, final Object arg4,
                    final Throwable throwable); @Override void error(final CharSequence message, final Object arg0, final Object arg1,
                    final Object arg2, final Object arg3, final Object arg4, final Object arg5,
                    final Throwable throwable); @Override void error(final CharSequence message, final Object arg0, final Object arg1,
                    final Object arg2, final Object arg3, final Object arg4, final Object arg5,
                    final Object arg6, final Throwable throwable); @Override void warning(final CharSequence message, final Object ... args); @Override void info(final CharSequence message, final Object ... args); @Override void debug(final CharSequence message, final Object ... args);  }### Answer:
@Test public void testLogDebugWithArguments() throws Exception { LoggerImpl.LOG_LEVEL = LoggerImpl.Severity.DEBUG; subject.debug("%s %s", "Hello", "World"); assertThat(new String(out.toByteArray(), UTF_8), is("com.sap.jma.logging.LoggerImplTest#DEBUG: Hello World\n")); }
