LangServerBootstrap { boolean isPipeEnabled(@Nonnull String[] args) { return args.length > 0 && PIPE_ARG.equals(args[0]); }  static void main(String[] args);  }### Answer:
@Test void isPipeEnabledPositive() { String[] args = new String[] {PIPES}; assertTrue(LangServerBootstrap.isPipeEnabled(args)); }
@Test void isPipeEnabledUseSocket() { String[] args = new String[] {}; assertFalse(LangServerBootstrap.isPipeEnabled(args)); }
@Test void isPipeEnabledInvalidArgument() { String[] args = new String[] {"invalidArgument"}; assertFalse(LangServerBootstrap.isPipeEnabled(args)); }
