### End-to-end Test Environment
To launch a e2e environment, please follow below steps.
1. Visit to the [e2e](./e2e) directory.
2. Run `docker-compose up` to launch 2 chains, a relayer and `the faucet service`.
3. Visit to the [http://localhost:8080](http://localhost:8080) with your browser.
#### Run faucet server manually
```bash
$ make build
$ ./bin/server --config-file config.yml
```
