context options for mount are not being applied

[bucketclan]

const context = { name: "foo", id: 1};

  const wrapper = mount(<MyComponent />, {
    context,
    childContextTypes: { name: PropTypes.string, id: PropTypes.number }
  });

  expect(wrapper.context().name).toBe("foo");

The default context values were initialised as follows:

const MyContext = React.createContext({ id: 0, name: "" });

Current behavior

The test is failing, with the following errors:

expect(received).toBe(expected) // Object.is equality

    Expected: "foo"
    Received: ""

      22 |   });
      23 |
    > 24 |   expect(wrapper.context().name).toBe("foo");
         |                                  ^

      at Object.toBe (src/App.test.js:24:34)

Test Suites: 1 failed, 1 total
Tests:       1 failed, 1 total

Expected behavior

I expect the value of name to be "foo".

enzyme does not yet support createContext. See #1553.
