I've been looking at the nice

prefect_test_harness

in 2.0 and am wondering if any such fixtures exist for 1.2? Are there any general guides for setting up tests for projects using prefect?

No to fixtures, but have you seen this page?

Yup, but I need to test flow-of-flows composition from a utility and believe I require mocked registration to do so

Ah yeah that is hard because it’s an API call to start the flow run
