Reproduction of error handling issue in React. Error Boundaries cannot prevent exceptions from escape, killing test runners like tape-run. See facebook/react#10474

Reproduction:

yarn install
yarn test

Expected output: (comment index.js:26 to see it)

# ErrorCatcher should work
Warning: render(): Rendering components directly into document.body is discouraged, since its children are often manipulated by third-party scripts and browser extensions. This may lead to subtle reconciliation issues. Try rendering into a container element created for your app.
ok 1 should be truthy
# Succesful test
ok 2 should be truthy

1..2
# tests 2
# pass  2

# ok

Resulting output:

> [email protected] test /home/michel/tmp/react-error-handling
> browserify index.js -t [ babelify --presets [ es2015 react ] ] | tape-run
