# Test applications during development

## To test an application you have been working on

- With the application open, from the Application menu, select Test Application, or click the Test Application icon on the toolbar.

A FactoryTalk View ME Station emulator opens on the development computer and runs the application. There is a two-hour time limit for using the run-time system on the development computer.

## To test a single graphic display

- With the graphic display open, from the View menu, select Test Display.

The objects in the display are activated and connected to the tags assigned to them. In this mode, only the tags connected to the display will work, not the links to other displays or the alarms or other functions.

Tip: | If you have set up local messages and graphic objects to use multiple languages, the messages and objects will be shown in the application's current language while in test mode.
