That means that your /tmp dir was cleaned out and Appium had crashed at some point, so your Mobile-Safari.app has been lost. Hopefully you have a backup! If not, redownload the iOS SDK.

You can also set a different path for appium to move the mobile-safari.app to so it doesn't get cleaned out on a machine reboot.

Thanks Jonathan!

I had to re-download the sdk. How can i modify the path for Appium to move the mobile safari app to a different location?

Thanks,

Girija

Set APPIUM_APP_BACKUP_DIR env variable to the directory you want

Hi, 

How can I set APPIUM_APP_BACKUP_DIR? using below is not working

Capability.setCapability("APPIUM_APP_BACKUP_DIR", "/MobileSafari.app");

Thanks, 

Naveed

Set APPIUM_APP_BACKUP_DIR env variable to the directory you want.

[Naveed Saleem]

You mean I should set it in my code(testcase) like, 

APPIUM_APP_BACKUP_DIR = "<path>"

wondering I need to create a new variable or it is some global variable, don't understand how to set it?

Thanks, 

[Eric Millin]

Yes, you can set it in your code.  http://stackoverflow.com/a/15058999

You can also set it on the cmd line when you start appium.

OSX: APPIUM_APP_BACKUP_DIR="<path>" appium [options]
Windows: set APPIUM_APP_BACKUP_DIR="<path>" & appium [options]
