This can be simplified to: expect(result).toMatchObject(expected);

[tgandrews]

This works if the test passes but if the objects don't match then you can get jestjs/jest#6730

This makes the error more readable when the test fails. I have added a comment and a tech debt ticket. https://trello.com/c/Ho4Rh8MH/333-resolver-tests-can-trigger-bug-in-jest
