m.deps

• Usage
• Signature

---

This function overwrites the reference to the window object that is used internally by Mithril. It is useful for injecting a mock window dependency for the purposes of testing and for running Mithril in non-browser environments. The mock object used by Mithril for its own test suite can be found in the development repo.

By default, Mithril uses window itself as the dependency. Note that Mithril only uses the mock object for browser APIs such as the DOM API and requestAnimationFrame, but relies on the environment for ECMAScript features like Object.keys.

---

Usage

Call it at the beginning of your test file to supply a mock window:

function testMithril(mockWindow) {
    window = m.deps(mockWindow);

    // Your tests here...
}

Signature

How to read signatures

Window m.deps(Object window)

where:
    Window :: Object<any>

• Object Window

  This should be either window or a mock of the window object.

  Mithril uses certain window methods that will need to be made available for complete test coverage, depending on your application:

  • window.document
  • Mithril also uses certain methods on the DOM node object
  • window.requestAnimationFrame/window.cancelAnimationFrame
  • Falls back to window.setTimeout/window.clearTimeout
  • window.location
  • window.history
  • window.scrollTo
  • window.XMLHttpRequest

• returns Window

  The returned window is the same as what is passed in.
