Hanging in Tests: const ui = await response.getInterface();

[javaspeak]

When I create a snap and change directory to:

packages/site

and run

npm run test

I get:

johndickerson@Johns-MacBook-Pro snap % npm run test

> snap@0.1.0 test
> jest

It is timing out on this method:

const ui = await response.getInterface();

Any ideas why this is hanging?

Do I need to start something else for this to work?

Thank you for your time.
