 An integration test is prepared for contracts and federators. To properly run integration test, you need check network config in the `truffle-config.js` and `package.json` in `bridge` folder with your test chains' configuration before run `npm run deployIntegrationTest`.
 
+For testing purposes only, an empty `test.local.federator.key` file is available in `federator/config`, which fulfills the role that a `federator.key` file would have in production.
+Also, a `test.local.config.js` configuration is provided in `federator/config` for the same purpose, acting as the `config.js` file would in a productive environment.
+
 1. Check `mnemonic.key` in `bridge`
 1. Check `infura.key` in `bridge`
-1. Check `federator.key` in `federator/config`
-1. Check `config.js` in `federator/config`
 1. Check your `networkName` in `bridge/migrations/4_deploy_erc1820.js` when your test network does not have **ERC1820:Pseudo-introspection Registry Contract** deployed.
