Welcome to my solution for the Test Automation Engineer Coding Challenge.

Approach

Language

I chose TypeScript with Bun as the runtime for this project. TypeScript is the language I am most comfortable with, and Bun simplifies the setup compared to Node.js, aligning with my goal to keep the solution straightforward.

Test Framework

I utilized the built-in Bun Test Runner as the test framework. It is Jest compatible and well-suited for the requirements of this project.

Project Overview

Setup

To streamline the configuration and initialization of Waku Nodes, I created a Docker Compose file ./docker-compose.yml. This file sets up two Waku Nodes with appropriate network configurations. The nodes are being started using the helper scripts:

• ./scripts/run-node-1.sh
• ./scripts/run-node-2.sh

I containerized the test as well. A separate Docker Compose file, docker-compose-tests.yml, builds and runs the test project.

To further simplify the setup, I created the script ./scripts/run-tests.sh, which:

1. Builds and starts the Waku Nodes.
2. Builds and starts the test project. Displays the test results.
3. Performs a teardown to clean up the environment.

For simplicity, all URLs and IP addresses are hardcoded.

Tests

Tests are organized within the ./tests/ directory, including two test suites:

• basic.test.ts - Test Suite 1 (Basic Node Operation)
• inter-node.test.ts - Test Suite 2 (Inter-Node Communication).

How to Run

Locally

Preconditions:

• Ensure Docker is installed and running.

Steps to Execute:

./scripts/run-tests.sh

GitHub Actions

Tests are integrated with GitHub Actions, allowing execution via pull requests or on-demand. You can find the workflow runs here.
