A hands-on case study builds a TypeScript model of a privacy door knob, writes clear requirement sentences, and implements Jasmine tests run in the browser via reveal.js. The talk shows using the Arrange Act Assert pattern to turn verbose scenarios into maintainable one-line specs with shared beforeEach setup, explains mocks versus unit scope, reports that tests give precise failure messages, and argues Copilot-generated tests are weaker than human-framed requirements. The approach improves design, speeds feedback, and the example suite runs and surfaces concrete failures.
