# GitHub Action Moropo features a GitHub action that can initiate a Moropo test run based on a user-defined ruleset. For example; triggering a test run on every PR, or per commit. As part of triggering the test run a user can also: * Pass a **build file** with the action in order to test on the latest binaries built by their CI-CD pipeline * Pass **env variables** to the test runner, allowing the user to change test behaviours based on the action configuration * Pass an **Expo release channel** to the test runner, instructing the runner to use a specific release channel. Apart from the [Initial CI Setup In Moropo](/ci-integration/initial-ci-setup-in-moropo.md), all installation and configuration instructions for the GitHub action can be found on the GitHub marketplace here - [Moropo - Trigger Mobile App Test Run](https://github.com/marketplace/actions/moropo-trigger-mobile-app-test-run) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
