mock

Load a module with it's require's mocked out

Works in both node and browserify

Example

var realB = require("./fixtures/b")

var b = mock("./fixtures/b", {
    fs: {
        readFileSync: function (uri) {
            if (uri === "clowns.txt") {
                return "some clowns"
            }
        }
    }
    , "./fixtures/c": null
    , "./fixtures/a": function () {
        return 42
    }
}, require)

// use b. It's reference to fs and fixtures/a have been replaced with
// your passed objects

Limitations:

• You have to require the thing your mocking out or browserify won't load it and all it's dependencies into the bundle.
• When you set a dependency to null your saying don't overload that dependency with this value, but do nuke it from the cache. This is useful when you want to mock out something ./fixtures/c depends on but not touch the implementation of ./fixtures/c

Installation

npm install mock
