End to end tests

[spacedmonkey]

Summary

Add e2e tests based on #126. There are a couple of small tweaks to the code base to make the tests possible.

There are some basic tests for on boarding, but these should be expanded maybe at a later date. Much of the onboarding tests are covered by unit tests.

Fixes #126
