Why Should Developers Automate?

Real-world examples show how spending just one extra hour automating tests after a feature can save days of bugs, frustration, and lost money later.

This session dives into a .NET microservice, but the concepts apply across architectures — monoliths, desktop apps, and more. (Code is in C#, but the ideas work in any language.)

It explores how developers can write E2E automated tests🤖 to validate APIs and event-driven workflows using real infrastructure. The setup spins up a microservice with Docker 🐳, connects it to a test project that runs inserts, updates, deletes, and verifies HTTP status codes, database states, and event bus triggers.

This developer🧑‍💻-focused automation complements QA processes, catching bugs earlier, boosting confidence, and reducing back-and-forth in the delivery cycle.

The result is faster⏱️ delivery🚀, fewer misunderstandings😵 between Dev and QA, and major cost savings 💸💸 by detecting issues before they reach production.

A real-world solution with working code, real infrastructure, and a practical model for testing integrated systems early and effectively.
