AwesomeCI Test Splitting Demo

This repository demonstrates test splitting in a continuous integration (CI) pipeline using a large-scale, multi-language codebase. It contains two main components:

• A PHP backend with a large number of test files.
• A React frontend application with unit tests.
• A simple way to build a Docker image and push it to AWS ECR

The purpose is to simulate real-world projects with high test volume and showcase test parallelization and dynamic splitting strategies in CI systems like CircleCI.
