# Continuous Integration

***

A GitHub Action is available for integrating `era-test-node` into your CI/CD environments. This action offers high configurability and streamlines the process of testing your applications in an automated way.

You can find the GitHub Action available in the [marketplace](https://github.com/marketplace/actions/era-test-node-action).

In CI tests, use `127.0.0.1` as the URL in hardhat.config.ts or for the provider to avoid '**Cannot connect to network**' errors.
