Governance Action Load Testing (based on cardano-node-tests)

This is an implementation of cardano-node-tests for governance action load testing

Agents

• 3 SPOs
• 90 Committee Members
• 100 DReps

Load Tests Applied on Following Gov Actions

• Drep and SPO Delegation
• Committee Update
• Constitution Update
• Protocol Patameter Update
• Treasury Withdrawal
• HardFork
• Info
• No Confidence

Load Test Scenarios

Scenario 1: (majority) (repeat for: each governance action type)

• Create 3 proposal of this type
• Each stake holders votes on the proposal with "proposal1" having the majority
• Proposal1 is enacted.

Scenario 2: (equal) (repeat for: each governance action type)

• Create 3 proposal of this type
• Each stake holders votes on the proposals with "proposal1" and "proposal2" having equal votes.
• The proposal submitted first to the chain is enacted

Scenario 3: (insufficient) (repeat for: each governance action type)

• Create 3 proposal of this type
• Each stake holders votes on the proposals, but none reaching the threshold
• None of the proposals are enacted

To run tests individually

1. run nix shell that has all the needed dependencies

   nix flake update --accept-flake-config --override-input cardano-node "github:IntersectMBO/cardano-node/master"  # change `master` to rev you want
   nix develop --accept-flake-config .#venv

2. prepare testing environment

   source ./prepare_test_env.sh conway

3. start the cluster instance

   Testing HardFork requires major protocol version 9

   ./dev_workdir/babbage_fast/start-cluster

   Testing other gov actions require major protocol version 10

   PV10=true ./dev_workdir/babbage_fast/start-cluster

4. run some tests

   To run a governance action load test with all scenarios

   pytest cardano_node_tests/tests/tests_conway/test_hardfork.py

   To run governance action load test with a specific scenario

   pytest -s -k test_hardfork_majority cardano_node_tests/tests/tests_conway/test_hardfork.py

5. stop the cluster instance

   ./dev_workdir/babbage_fast/stop-cluster
