| 1 | # Manual Testing Fixtures |
| 2 | |
| 3 | This folder exists for **React contributors** only. |
| 4 | If you use React, you don't need to worry about it. |
| 5 | |
| 6 | These fixtures verify that the built React distributions are usable in different environments. |
| 7 | **They are not running automatically.** (At least not yet. Feel free to contribute to automate them.) |
| 8 | |
| 9 | Run them when you make changes to how we package React and ReactDOM. |
| 10 | |
| 11 | ## How to Run |
| 12 | |
| 13 | First, build React and the fixtures: |
| 14 | |
| 15 | ``` |
| 16 | cd react |
| 17 | npm run build |
| 18 | node fixtures/packaging/build-all.js |
| 19 | ``` |
| 20 | |
| 21 | Then run a local server, e.g. |
| 22 | |
| 23 | ``` |
| 24 | npx pushstate-server . |
| 25 | ``` |
| 26 | |
| 27 | and open the following URL in your browser: [http://localhost:9000/fixtures/packaging/index.html](http://localhost:9000/fixtures/packaging/index.html) |
| 28 | |
| 29 | You should see two things: |
| 30 | |
| 31 | * A number of iframes (corresponding to various builds), with "Hello World" rendered in each iframe. |
| 32 | * No errors in the console. |
