IOS code signing required for product type 'Unit Test Bundle' in SDK 'iOS 9.2'

Question

I want to test my application on iPhone 5s. and he has the latest version of ios. so I uninstalled the old Xcode V 7.0.1 and installed the new version v 7.2.

After installing v 7.2, I get below the error.

CodeSign error: product type requires signing of the 'Unit TestBundle' code in the 'iOS 9.2' SDK

I ask this question code-signing-is-required-for-product-type-unit-test-bundle-in-sdk-ios-8-0 and try all the answers, but still I have this problem.

I have a build assembly target as well as a tab with information. even I do not get a signin error to fix the problem. but still not able to run the application on my test device.
