Description

Our tests throughout the codebase have two sources of duplication:

1. Multiple test harnesses all starting up a node of subset of one
2. The test harnesses have duplicate setup to our full node in the runner

For 1) we should combine them all into a single test harness (in test-utils). For 2) we should update that single test harness to use the same setup as the runner to make the tests as similar to a production node as possible. I have a WIP for 1) here. Will finish this up tomorrow.
