+# Rerequire
+
+Dependency injection for Node.js modules. This module works the same as require but you can mock modules and globals.
+
+```js
+var rerequire = require('rerequire');
+
+rerequire(/* file to module you want to test */, /* module mocks */, /* global mocks */);
+```
+
+## Example
+
+```js
+var test_file = rerequire('./test_files', {
+  'http': 'http mock', // Mock global module
+  './mod': 'mock mod', // Mock local module
+}, {
+  'Date': 'mock date', // Mock gloval
+});
+```
