Running the FluentUI Tester on Win32

FluentUI Tester is the test app that we use to test our FluentUI components during development.

Launch FluentUI Tester app on Win32

1. Make sure you've installed the Standard React Native dependencies and Node.js from the Prerequisites section.

2. Next, clone and build the repo. If you already have a clone of the repo, make sure you've pulled the latest from the main branch (run git pull from your clone's main branch). You can verify you have the latest commits by running git log which lists all the commits from your branch with dates. Ensure commits are from a recent date or match the latest commits here. To exit the git log view, press the letter 'q' (for "quit").

3. Then go into apps\win32 folder:

``
cd apps\win32
`

3. Build the FluentUI Tester bundle:

`
yarn bundle
`

4. Launch the FluentUI Tester app:

`
yarn run-win32
`

5. You will see the FluentUI Tester show up in a new window.

Debug FluentUI Tester app with direct debugging

Note: we recommend using Visual Studio Code for direct debugging.

1. Follow steps #1-3 above.
2. Build the FluentUI Tester bundle with dev option. This will ensure source map is included in the bundle.

`
yarn bundle-dev
`

3. Launch the FluentUI Tester app:

`
yarn run-win32
`

4. Inside ReactTest, open the debug option menu and select the checkbox Use Direct Debugger

Dependencies

Dependencies are managed by
@rnx-kit/align-deps.
If you're looking to upgrade react-native, use the interactive upgrade command:

`sh
yarn rnx-align-deps --set-version
`

This command will ensure that all relevant packages are bumped correctly.
