Test Those Metrics!

The code in this repo accompanies a talk given at the Rust London TrueLayer Takeover in December 2021, as a demonstration of one way the observability of a microservice can be exercised and verified during automated tests.

Disclaimer: This code is provided AS IS. It is NOT intended as an example of a production-ready service.

Prerequisites

• Rust, version >= 1.56.1.

To Test

Run cargo test. No additional services are assumed to be running.

Layout

This repository contains a cargo workspace consisting of two crates:

• cart_server, the main binary, that hosts our HTTP server;
• mock_jaeger_collector, a library crate consisting of a mock Jaeger collector service, for use in black box testing the cart server.
