It is used to monitor\nand report on node performance by executing transactions and measuring response-time.\n\n## Key Features\n\n- 🚀 Batch transactions to make stress testing easier to orchestrate\n- 🛠 Multiple stress testing modes: REALM_DEPLOYMENT, PACKAGE_DEPLOYMENT, and REALM_CALL\n- 💰 Distributed transaction stress testing through subaccounts\n- 💸 Automatic subaccount fund top-up\n- 📊 Detailed statistics calculation\n- 📈 Output cycle run results to a file\n\n## Results\n\nTo view the results of the stress tests, visit the [benchmarks reports for supernova](https://github.com/gnolang/benchmarks/tree/main/reports/supernova).\n\n## Usage Example\n\nTo run a stress test with `supernova`, you will need to have `go 1.19` or greater.\n\n1. Build out the binary\n\nTo build out the binary, run the following command:\n\n```bash\nmake build\n```\n\n2. Run the stress test by specifying options\n\n```bash\n./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\n```\n\nThis will run a stress test against a Gno TM2 node running at `http://localhost:26657`. The test will use `5`\nsub-accounts, and send out `100` transactions. The sub-accounts are derived from the specified mnemonic. Finally,\nresults are saved\nto a file `result.json`.\n\nFor any stress test run, there need to be funds on a specific address.\nThe address that is in charge of funds distribution to subaccounts is the **first address** with index 0 in the\nspecified mnemonic. Make sure this address has an appropriate amount of funds before running the stress test.\n\n![Banner](.github/demo.gif)\n\n`supernova` supports the following options:\n\n```bash\nUSAGE\n  [flags] [\u003carg\u003e...]\n\nStarts the stress testing suite against a Gno TM2 cluster\n\nFLAGS\n  -batch 100              the batch size of JSON-RPC transactions\n  -chain-id dev           the chain ID of the Gno blockchain\n  -mnemonic string        the mnemonic used to generate sub-accounts\n  -mode REALM_DEPLOYMENT  the mode for the stress test. Possible modes: [REALM_DEPLOYMENT, PACKAGE_DEPLOYMENT, REALM_CALL]\n  -output string          the output path for the results JSON\n  -sub-accounts 10        the number of sub-accounts that will send out transactions\n  -transactions 100       the total number of transactions to be emitted\n  -url string             the JSON-RPC URL of the cluster\n```\n\n## Modes\n\n### REALM_DEPLOYMENT\n\nThe `REALM_DEPLOYMENT` mode is pretty straightforward - it is a simple `Realm` deployment mode from accounts.\nThis mode sends out transactions that are deploy transactions for a realm holding state.\n\n### PACKAGE_DEPLOYMENT\n\nThe `PACKAGE_DEPLOYMENT` is similar to `REALM_DEPLOYMENT`. This mode also sends out transactions, but these transactions\ndeploy a package.\n\n### REALM_CALL\n\nThe `REALM_CALL` mode deploys a `Realm` to the Gno blockchain network being tested before starting the cycle run.\nWhen the cycle run begins, the transactions that are sent out are method calls.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgnolang%2Fsupernova","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgnolang%2Fsupernova","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgnolang%2Fsupernova/lists"}
