Pull request overview
This PR adds comprehensive end-to-end testing infrastructure for the Rooch pruner functionality. The implementation includes TypeScript test utilities for collecting and validating Prometheus metrics, a Move test contract for simulating object lifecycle operations, and detailed documentation.
Key Changes
- Added Prometheus metrics client and test reporter utilities for E2E validation of pruner behavior
- Created a Move contract (
pruner_test::object_lifecycle) to test object creation, updates, and deletion scenarios that trigger pruning - Integrated pruner metrics into the RPC server and refactored metrics from
StateDBMetricsto a dedicatedPrunerMetricsmodule

- [nitpick] The
metricsPortis generated but never passed as a command-line argument to the Rooch server. The metrics port is only set via an environment variableMETRICS_HOST_PORT=${metricsPort}at line 148. While this may work if the Rooch server reads this environment variable, it would be more explicit and maintainable to also pass it as a command-line argument like--metrics-port ${metricsPort}if the server supports it. Verify that the environment variable approach is the intended configuration method.
const metricsPort = await getUnusedPort()
const cmds = ['server', 'start', '-n', 'local', '-d', 'TMP', '--port', port.toString()]

The label matching in findSample should use === for strict equality, but it currently does. However, there's a potential bug: the Prometheus format typically uses double quotes around label values (e.g., phase="SweepExpired"), but the regex at line 137 removes quotes. If a metric has a label value that naturally contains quotes or special characters, this simple replacement may not work correctly. Consider a more robust label parsing approach.
