cw-load-test's Introduction

cw-load-test

cw-load-test is a tool for load testing Cosmwasm networks based on tm-load-test.

Requirements

In order to build and use the tools, you will need:

Go 1.17+
make

Building

To build the cw-load-test binary in the build directory:

make build

Usage

Require WALLET and CHAINID environment variables.

# wallet paraphrase
export WALLET="dss hgg ssa yyrre ere ere erre ..."
export CHAINID=torri-1

1. Storing wasm code

This command generates different wasm files from a custom wat (text format) using wasmtime-go, and sends 6 wasm codes with a timeout height (+5).

./build/cw-load-test -b 5 -r 6 \
    --wat-path res/code.wat \
    --broadcast-tx-method async \
    --lcd http://127.0.0.1:1317 \
    --endpoints ws://127.0.0.1:26657/websocket \
    --gas 2000000 --gas-prices 0.00ucosm

-b: Max block to wait txs complete
-r: Txs in batch transaction
--lcd: Cosmos API
--endpoints: Tendermint RPC

2. Execute contract

Send 10 MsgExecuteContract txs with timeout height +5. Use custom contract

./build/cw-load-test -b 5 -r 10 \
    --contract wasm1hm4y6fzgxgu688jgf7ek66px6xkrtmn3gyk8fax3eawhp68c2d5qphe2pl
    --exec-msg '{"allocate_memory": {"limit": 500}}' \
    --broadcast-tx-method async \
    --lcd http://127.0.0.1:1317 \
    --endpoints ws://127.0.0.1:26657/websocket \
    --gas 2000000 --gas-prices 0.00ucosm

--contract: Contract to be executed.
--exec-msg: Execute msg to send to contract.
