How to run a fresh install of the application every time unit tests are run?

Question

I've setup some XCTest unit tests for my application and would like every time I run tests for it to run in a brand new install of the application. Currently when I run subsequent tests it runs the tests in the same application that was run before which has a lot of state information already changed by the previous tests.

Is there a way to indicate that when you run unit tests that it should run the tests on a fresh version of your application?

@SteveRosenberg Clean just cleans your 'build' directory, it doesn't uninstall apps. — Shizam, Oct 08 '14 at 17:48

Maybe this works, but only for Simulator.

In Product > Scheme > Edit Scheme...

enter image description here

xcrun simctl is command line utility to control the iOS Simulator. This uninstalls com.yourcompany.AppName application from booted simulator before running tests.

I don't know how to do like this for real device :(

One could use `ios-deploy` in the same way perhaps? – Vish Jan 13 '16 at 07:51
The way to use this in-between tests is to run it in a yml file or shell within Jenkins – Laser Hawk Jan 04 '17 at 00:51
if i want only uninstallation for ui tests how can i do that? i dont want in unit tests. – Sazzad Hissain Khan Mar 21 '17 at 11:19
@LaserHawk could you elaborate more? Perhaps in a separate answer? – IvanMih Jan 25 '21 at 12:27

In addition to @rintaro's answer, if you set "Provide build settings from" to your app, you can add a generic command, which will keep working when your bundle id changes:

xcrun simctl uninstall booted ${PRODUCT_BUNDLE_IDENTIFIER}

Why the downvote? What have you tried? What makes you so certain this doesn't work? – Koen. Mar 31 '16 at 14:45
