In a similar vein, I use Storybook to build my presentational components, and run each story in a try/catch to check for "explosions". If you add some dependency injection to look for `console.warn` or `console.error` calls, you can catch failed PropTypes or similar. Today you can even combine all of these with Jest's new "Tree Snapshot Testing" to compare the actual output of `render` with an expected/approved output. Finally, you can use your stories in combination with a service like Browserstack or SauceLabs to run these tests across platforms, and even take screenshots of each story and compare them to test for styling regressions and cross-platform differences.
