Create Integration test helper to initialize components to work with auto-tagging

[kylemellander]

Currently, when running integration tests, the updated component is not initialized, which makes any component based data-test attributes not show up. We should write an initializer (or even just docs explaining how) that can be run in integration tests to run the initializer in the tests, so that data-test attributes are populated.

I am willing to help if you point me (in source code) to the right direction.
