# How to verify the integration in your app with the SDK

#### v2.x

## Intro to the Doctor App

The SDK comes with integration verification tool - "Doctor App". The "Doctor App" is a tool that helps verify the SDK integration in your project by simulating a typical user flow in the application. When the "Doctor app" is enabled, it will pop up as part of the app flow and will guide the developer on simulating a user flow to gather the required information for testing the integration.

## The Doctor App's bundle

The "Doctor App" includes assets that are used for the UI. Those assets are required only for the "Doctor App" usage and are not needed in your app production build. In order minimize the SDK footprint, those assets are loaded dynamically in run time (from v2.1.0).\
If you run the "Doctor App", those assets will be loaded automatically (internet connection is required).

## Enable the Doctor App

In order to enable this feature, call the `PerimeterX/start(appId:delegate:enableDoctorCheck:completion:)` function with the `enableDoctorCheck` as `true`. Here is an example:

```kotlin
PerimeterX.INSTANCE.start(this, "<APP_ID>", this, true) { success ->

}
```

```java
PerimeterX.INSTANCE.start(this, "<APP_ID>", this, true, success -> {
	return null;
});
```

> **Development only!**
>
> This feature is for development only and should not be shipped as enabled with the application to the store.

3. Test selection screen\
   In this screen you can select between two different types of tests:
   1. Native app framework - to test your native URL requests.
   2. Web view framework - to test your web view URL requests.\
      When you are done executing a test, you will return to this screen to enable you to start the other test.\
