# SKAdTestPostback

A test postback that contains ad conversion information in the testing environment.

## Declaration

```swift
class SKAdTestPostback
```

## Overview

Overview Use this class to create test postbacks to use for unit testing. In the production environment, the system creates a postback after a user installs an advertised app. The advertised app is responsible for registering the installation and may update the conversion value. The system sends the postback after a timer expires. In the testing environment, you can mimic a postback by creating it directly. You control the property values within the postback. Use it to test your app’s ability to register the app installation and update conversion values, and to test your server’s ability to receive postbacks.
