Testing React Applications
summary
Shows a small Todo app and proves tests actually catch behaviour: adding, toggling and deleting items work and regressions get prevented. Uses tape as the test runner, React TestUtils + shallow rendering for fast unit checks, jsdom and mount/Enzyme for DOM interaction, and browser bundling to run tests in Chrome. Core state logic is extracted to plain functions so pure-unit tests run quickly. All examples build and run successfully.
