# `.context([key]) => Any`

Returns the context hash for the root node of the wrapper. Optionally pass in a prop name and it
will return just that value.

root component instance.



#### Example


```jsx
const wrapper = mount(
  <MyComponent />,
  { context: { foo: 10 } }
);

expect(wrapper.context().foo).to.equal(10);
expect(wrapper.context('foo')).to.equal(10);
```
