# init(keyPath:object:)

Creates an expectation that any KVO change to the specified key path of the observed object fulfills.

## Declaration

```swift
convenience init(keyPath: String, object: Any)
```

## Parameters

- `keyPath`: The key path to observe.
- `object`: The object to observe.

## Discussion

Discussion This initializer sets up KVO observation for keyPath with the following NSKeyValueObservingOptions: new old The inclusion of the new and old options means that any custom KVO handler you provide in the expectation’s handler property receives a change info dictionary that contains the newKey and oldKey keys.
