効率的なテストのためにコンソール ログを無効にする方法は?

<code class="javascript">console.log = function() {}</code>

<code class="javascript">var logger = function() {
  var oldConsoleLog = null;
  var pub = {};

  pub.enableLogger = function() {
    if (oldConsoleLog == null) return;
    window['console']['log'] = oldConsoleLog;
  };

  pub.disableLogger = function() {
    oldConsoleLog = console.log;
    window['console']['log'] = function() {};
  };

  return pub;
}();</code>

<code class="javascript">$(document).ready(
  function() {
    console.log('hello');

    logger.disableLogger();
    console.log('hi', 'hiya'); // These won't show up
    console.log('this wont show up in console');

    logger.enableLogger();
    console.log('This will show up!');
  }
);</code>
