DevTools has good unit test coverage but no e2e test coverage. This is because the support for testing extensions is pretty limited in e2e testing libraries. That being said, we could probably get 80% of the value of e2e testing leveraging our react-devtools-inline package.

We should create a few example tests (e.g. load hook names, select a component and edit props/state, etc) to see how viable this is.

For now, these tests should not block PRs from landing.
