## Development
Requires Node 10+. For best results, use yarn. The basic commands are:
```sh
# compile the code
yarn build
# run unit tests
yarn test
# format and lint the code
yarn format & & yarn lint
```
### Integration tests
To run the entire test suite, you need to run a local blockchain to test against. This should work on any Linux/OSX system with docker installed.
```sh
./scripts/cosm/start.sh
COSMOS_ENABLED=1 yarn test
./scripts/cosm/stop.sh
```
