(WIP) Add integration tests

This adds integration tests that test the core functionality of the SDK.

I’ve tried to make them quite readable, which has the side effect of
making them quite verbose, but my experience in the past has been that
this kind of test can be extremely difficult to understand when not
adequately commented.

TODO still need to add tests for component locking functionality

Resolves COL-56.
