Fake It While You Make It
summary
Builds SWEATHR on a real weather API then walks four concrete approaches: live requests (slow, flaky), Webmock stubs (fast but brittle), a Sinatra fake web app with Capybara Discoball (full‑stack but extra maintenance), and VCR cassettes (record once, replay until stale). Recommends layering: an API client, a CurrentConditions mapper, and a weather module with a test‑mode fake client. Demonstrates each tool, shows tradeoffs, and notes tests often cost more time than the implementation.
