@ -34,3 +34,22 @@ Until `compat-table` is a standalone npm module for data we are using the git ur
`"compat-table": "github:kangax/compat-table#gh-pages",`
So we update and then run `npm run build-data`. If there are no changes, then `plugins.json` will be the same.
### Writing Tests
#### General
All the tests for `babel-preset-env` exist in the `test/fixtures` folder. The
test setup and conventions are exactly the same as testing a Babel plugin, so
please read our [documentation on writing tests](https://github.com/babel/babel/blob/master/CONTRIBUTING.md#babel-plugin-x).
#### Testing the `debug` option
Testing debug output to `stdout` is similar. Under the `test/debug-fixtures`,
create a folder with a descriptive name of your test, and add the following:
* Add a `options.json` file (just as the other tests, this is essentially a
`.babelrc`) with the desired test configuration (required)
* Add a `stdout.txt` file with the expected debug output. For added
convenience, if there is no `stdout.txt` present, the test runner will
generate one for you.
