When to  »Unstub » a Component in a Vue.js Unit Test

To test a component in isolation you can replace it’s children components by stubbing them. Vue Test Utils can automatically do this for you with a feature called shallowMount.

But what happens if a component is tightly coupled to one of its children? You can still use shallowMount, but you’ll then have to selectively "unstub" the tightly coupled child.
