## What changed? - Add generic hook interface for fine-grained control of behavior in tests - Use the hooks for matching varying behavior tests (force load balancer to target partitions and disable sync match) - Use the hooks to force a race condition in an update-with-start test (by @stephanos) ## Why? To write integration/functional tests that require tweaking behavior of code under test, without affecting non-test builds. ## Potential risks Hooks are disabled by default, so there should be zero risk to production code, and zero overhead (assuming the Go compiler can do very basic inlining and dead code elimination). The downside is that functional tests now have to be run with `-tags test_dep` everywhere. --------- Co-authored-by: Stephan Behnke <[email protected]>
