To resolve errors from jest test such as:

Error: Not implemented: navigation (except hash changes)

If the unit test is testing for link e.g. <a href="link"></a>. Mocking window.location will not work. Reconfiguring the jsdom in Jest with a custom one works. Can use this package https://github.com/simon360/jest-environment-jsdom-global to expose the global jsdom and reconfigure url property to make the error go away.
