Testing Tools and Their Friends
summary
Live demo shows Cypress end-to-end runner driving a browser, CI via CircleCI orb and start-server-and-test, Istanbul/nyc instrumentation plus a Cypress code-coverage plugin that records coverage, and Percy for visual diffs. One simple E2E test produces 76% coverage from one test, then combining a targeted unit spec hits ~100% coverage. Functional tests pass after CSS removal but Percy flags visual regressions, proving the toolchain catches behavior, coverage gaps and visual breakage while running and reporting automatically.
