Overview

supernova is a command-line interface (CLI) tool for stress-testing Gno Tendermint 2 networks. It is used to monitor and report on node performance by executing transactions and measuring response-time.

Key Features

• 🚀 Batch transactions to make stress testing easier to orchestrate
• 🛠 Multiple stress testing modes: REALM_DEPLOYMENT, PACKAGE_DEPLOYMENT, and REALM_CALL
• 💰 Distributed transaction stress testing through subaccounts
• 💸 Automatic subaccount fund top-up
• 📊 Detailed statistics calculation
• 📈 Output cycle run results to a file

Usage Example

To run a stress test with supernova, you will need to have go 1.19 or greater.

1. Build out the binary

To build out the binary, run the following command:

make build

2. Run the stress test by specifying options

./build/supernova -sub-accounts 5 -transactions 100 -url http://localhost:26657 -mnemonic "source bonus chronic canvas draft south burst lottery vacant surface solve popular case indicate oppose farm nothing bullet exhibit title speed wink action roast" -output result.json

This will run a stress test against a Gno TM2 node running at http://localhost:26657. The test will use 5 sub-accounts, and send out 100 transactions. The sub-accounts are derived from the specified mnemonic. Finally, results are saved to a file result.json.

For any stress test run, there need to be funds on a specific address. The address that is in charge of funds distribution to subaccounts is the first address with index 0 in the specified mnemonic. Make sure this address has an appropriate amount of funds before running the stress test.

supernova supports the following options:

USAGE
  [flags] [<arg>...]

Starts the stress testing suite against a Gno TM2 cluster

FLAGS
  -batch 20               the batch size of JSON-RPC transactions
  -chain-id dev           the chain ID of the Gno blockchain
  -mnemonic ...           the mnemonic used to generate sub-accounts
  -mode REALM_DEPLOYMENT  the mode for the stress test. Possible modes: [REALM_DEPLOYMENT, PACKAGE_DEPLOYMENT, REALM_CALL]
  -output ...             the output path for the results JSON
  -sub-accounts 10        the number of sub-accounts that will send out transactions
  -transactions 100       the total number of transactions to be emitted
  -url ...                the JSON-RPC URL of the cluster

Modes

REALM_DEPLOYMENT

The REALM_DEPLOYMENT mode is pretty straightforward - it is a simple Realm deployment mode from accounts. This mode sends out transactions that are deploy transactions for a realm holding state.

PACKAGE_DEPLOYMENT

The PACKAGE_DEPLOYMENT is similar to REALM_DEPLOYMENT. This mode also sends out transactions, but these transactions deploy a package.

REALM_CALL

The REALM_CALL mode deploys a Realm to the Gno blockchain network being tested before starting the cycle run. When the cycle run begins, the transactions that are sent out are method calls.
