Add integration testing scripts

[martriay]

Although we currently require PRs to add some form of manual integration test, it's currently too open ended and hard to set up.

We should have some set up integration test scripts to test basic functionality, or at least provide enough scaffolding to quickly write a integration test any reviewer can then go and reproduce.

Moving this back to the backlog until we have more clarity whether is worth it and what we want to do

Closing because we don't think the library benefit significantly from integration testing at this stage.
