execution.\n\n`inject-loader` was inspired by, and builds upon ideas introduced in [jauco/webpack-injectable](https://github.com/jauco/webpack-injectable).\n\n### Usage\n\n[Documentation: Using loaders](http://webpack.github.io/docs/using-loaders.html)\n\nUse the inject loader by adding the `inject-loader!` [inline loader](https://webpack.js.org/concepts/loaders/#inline) when you use `require`, this will return a function that can used in test code to modify the injected module.\n\nBy default all `require` statements in an injected module will be altered to be replaced with an injector, though if a replacement it not specified the default values will be used.\n\n### Examples\n\nGiven some code in a module like this:\n\n```javascript\n// MyStore.js\n\nvar Dispatcher = require('lib/dispatcher');\nvar EventEmitter = require('events').EventEmitter;\nvar handleAction = require('lib/handle_action');\n\nDispatcher.register(handleAction, 'MyStore');\n```\n\nYou can manipulate it’s dependencies when you come to write tests as follows:\n\n```javascript\n// If no flags are provided when using the loader then\n// all require statements will be wrapped in an injector\nMyModuleInjector = require('inject-loader!MyStore')\nMyModule = MyModuleInjector({\n  'lib/dispatcher': DispatcherMock,\n  'events': EventsMock,\n  'lib/handle_action': HandleActionMock\n})\n```\n\nThere are a few examples of complete test setups for both Webpack 1, 2, 3 \u0026 4 in the [`example`](./example) folder.\n\n## License\n\nMIT
