# Testing the App

When you are done with building the App using our [Constructor](https://kb.mobsted.com/article/l6t1xqhokp-constructor) you might want to check how the App would look like from the AppUser perspective.

There are several ways to do that.

## Live Preview <a href="#live_preview" id="live_preview"></a>

Using Live preview from the [Constructor](https://kb.mobsted.com/article/l6t1xqhokp-constructor). Just click on the corresponding button in the top right side of the screen.![](https://storage.googleapis.com/helpdocs-assets/jyme83anlw/articles/wzqh6oojs5/1547202425940/ezgif-com-video-to-gif-1.gif)

## Running the App as an Object <a href="#running_the_app_as_an_object" id="running_the_app_as_an_object"></a>

The second approach is to launch the app from the perspective of the particular [Object](https://kb.mobsted.com/article/sf7369s2zb-objects).

You can do that by navigating to the Objects section and select Open App in the LoginURL column.![](https://storage.googleapis.com/helpdocs-assets/jyme83anlw/articles/wzqh6oojs5/1547443630905/ezgif-com-video-to-gif-2.gif)

Note: We recommend using the second approach because it would give you more accurate way of testing. In real life the App is always ran using **SOME OBJECT**.
