## m.deps
---
[Usage](#usage)
[Signature](#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`:
```javascript
function testMithril(mockWindow) {
window = m.deps(mockWindow);
// Your tests here...
}
```
---
### Signature
[How to read signatures](how-to-read-signatures.md)
```clike
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.
