Development and Testing

Build Instructions

To compile the contract, developers can use the following command:

gh repo clone eosnetworkfoundation/eosio.reward
cd eosio.reward
git checkout v1.0.0-rc1
./build.sh

Testing Framework

The contract includes a comprehensive testing suite designed to validate its functionality. The tests are executed using the following commands:

$ npm test

> test
> bun test

Exported memory errors

TypeError: undefined is not an object (evaluating 'this.memory.buffer')

If you're using a version of CDT to build that doesn't support exported memory, you'll need to export it manually for VeRT tests to work.

# Grab wabt
sudo apt-get install wabt

# Create a temporary wat file and export the memory
wasm2wat eosio.reward.wasm | sed -e 's|(memory |(memory (export "memory") |' > eosio.reward.wat
wat2wasm -o eosio.reward.wasm eosio.reward.wat
rm eosio.reward.wat

You can also use the ./build.sh script that will handle building and exporting memory for you.
