m.deps

---

Usage Signature

---

This is a testing method to set the window object in an environment that does not have it (such as the server). It will normally not be used in an application, as window is already available to Mithril. For normal (client-side) use of mithril, this method will not be used.

It is used in Mithril's testing suite, and can be used to supply a mock window for browserless testing.

---

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...
}

How to read signatures

Window m.deps(Object window)

where:
	Window :: Object<any>

• Object Window

  This should be 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 that passed in.
