Introduction

Imagine you want to test this module:

This can especially be a problem if the module is not idempotent[like mongoose models](https://github.com/jhnns/rewire/issues/27).

**Changing globals**<br>

Be careful, if you do something like this you'll change your globalconsole instance.

**Dot notation**<br>

myModule.__set__("console.log",function () {/* be quiet*/ });

myModule.__set__("console", {

log:function () {}

});

This replaces`console` just inside`myModule`. That is, because rewire is using`eval()` to turn the key expression into an assignment. Hence, calling`myModule.__set__("console.log", fn)` modifies the`log` function on the*global*`console` object.

**Globals with invalid variable names**<br>

rewire imports global variables into the local scope by prepending a list of`var` declarations:
