# Manual Testing Fixtures This folder exists for **React contributors** only. If you use React you don't need to worry about it. These fixtures verify that the built React distributions are usable in different environments. **They are not running automatically.** (At least not yet, feel free to contribute to automate them.) Run them when you make changes to how we package React, ReactDOM, and addons. ## How to Run First, build React and the fixtures: ``` cd react npm run build cd fixtures node build-all.js ``` Then run a local server at the root of the repo, e.g. ``` npm i -g pushstate-server cd .. pushstate-server . ``` (Too complicated? Send a PR to simplify this :-). Then open the corresponding URLs, for example: ``` open http://localhost:9000/fixtures/globals.html open http://localhost:9000/fixtures/requirejs.html open http://localhost:9000/fixtures/systemjs.html open http://localhost:9000/fixtures/browserify/index.html open http://localhost:9000/fixtures/brunch/index.html open http://localhost:9000/fixtures/rjs/index.html open http://localhost:9000/fixtures/systemjs-builder/index.html open http://localhost:9000/fixtures/webpack/index.html open http://localhost:9000/fixtures/webpack-alias/index.html ``` You should see two things: * "Hello World" fading in with an animation. * No errors in the console.
