# 4. Test your app on TestFlight (optional)
[TestFlight](https://developer.apple.com/testflight/) allows us to test and share the app before release it to the App Store, it's completely optional to use Testflight, but allow us to be sure our app works as expected before the app store publication.
Once the build is uploaded and processed in the [App Store Connect](https://appstoreconnect.apple.com) we can enter in the TestFlight section and create different groups with the users we want to test our application.
TestFlight is great for:
* Test Push Notifications
* Make sure your app works as expected before make it public
* Test DeepLinks
### Add test users
1\. In **App Store Connect** click **Users and Access** at the top.
2\. Click the **+** button.
3\. Fill the **New User** form. Make sure you check the app(s) you want them to have access to.
4\. Click **Invite**.
The user will need to open the email and click on **Accept invitation**.
### Add testers to Internal Testing
Users added to this group can access the app without needing Apple to do any review process. It's the quickest way to test your app with a bunch of users (up to 10.000).
1\. In **App Store Connect**, go to **Apps** and **click the app** you want to add testers to.
2\. At the top tab menu, click **Testflight**,
3\. In **Internal testing**, click the **+** button.
4\. In the **Create New Internal Group** modal window, enter a **name**. For example, "Testers" and click **Create**.
5\. A new section will appear named as the group created. click the **+** button right after the title.
6\. In the **Add Testers to the Group** modal window, **select** the testers and click **Add**.
The users will need to click on the **View in TestFlight** button from the email they received to see the app in TestFlight. Then accept and install the app.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.bravostudio.app/app-publication/publishing-your-app/ios-publication-complete-process/testflight.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
