  +## Running the tests
  +
  +First of all you will need an instance of wasmd running. From the root directory of this repository:
  +
  +```sh
  +./scripts/wasmd/start.sh && ./scripts/wasmd/init.sh
  +```
  +
  +You will also need a faucet. From the root directory of this repository:
  +
  +```sh
  +cd packages/faucet
  +yarn start-dev
  +```
  +
  +The tests need to be told you are running the faucet via an environmental variable:
  +
  +```sh
  +export FAUCET_ENABLED=1
  +```
  +
  +Finally run the tests from this directory:
  +
  +```sh
  +yarn test
  +```
