tasks-dotnet
A representative xUnit test from the suite, written in Given-When-Then style.
tasks-dotnet is a to-do application I build as a hands-on exercise in clean coding and Extreme Programming: small, test-first steps through the Red-Green-Refactor cycle, kept honest by unit and end-to-end tests running in CI.
The goal
Keep a realistic application continuously shippable by growing it test-first, so design stays simple and every change is backed by a failing-then-passing test.
What I built
- A C# domain (
TaskServiceand friends) grown with xUnit tests in Given-When-Then / Arrange-Act-Assert style. - Playwright end-to-end tests, written in TypeScript, that exercise real user flows.
- A GitHub Actions pipeline that runs the tests and publishes results on every push.
Practices on display
- Red-Green-Refactor: write a failing test, make it pass, then improve the design.
- Clean code and simple design over speculative abstraction.
- Unit tests for logic, Playwright for real end-to-end behavior.
I am currently modernizing this project with Claude Code, applying the same responsible AI-assisted engineering I use elsewhere: agents accelerate the work while the tests keep it honest.
