Testing Web Apps in the AI Era
Trust the code you ship! Learn to direct AI agents toward tests that actually catch regressions. Generate unit tests with Vitest, mocked data layers with MSW, and full user-flow coverage with Playwright.
Two Decades of Software Engineering Experience
Direct agents to write tests that actually matter
Direct coding agents to produce tests that give you confidence in your software. Leverage Vitest for fast unit tests, Mock Service Worker for mocking backend responses to test how your app handles different data conditions, and Playwright for end-to-end tests that verify the whole app works from a user’s perspective. Wether AI writes a little or a lot of your code, establish testing strategies that let you move fast while still catching the bugs that matter.
What You Will Master
- Prompt and direct coding agents to generate meaningful tests instead of padding for coverage numbers
- Know which layer of your app each testing tool is actually responsible for
- Write Vitest unit tests that verify component behavior, not implementation details
- Use Mock Service Worker to mock backend responses and test how your app reacts to real-world data conditions
- Set up Playwright end-to-end tests that catch integration failures before users do
- Build a testing strategy that complements a TypeScript-first codebase
Prerequisites
- Experience building TypeScript applications
- Basic familiarity with a coding agent (Claude Code, Codex, etc)
Who is this for?
This workshop is for software engineers wanting to establish better testing workflows. It’s especially relevant for teams that have adopted TypeScript but haven’t extended the same rigor to their tests.
