Code coverage result is not accurate to real coverage in Xcode 7

Question

I am running test cases in application with enabled code coverage data Xcode 7 Beta 2. But I am able to get only few files coverage data while my all test cases are running succ

Answer 1

IT WORKS.

1. Since Apple released @testable keyword to import your project into test target, you don't have to add your files to both target anymore:

2. So just remove every file from your test target:

3. Wherever you need access to your file from your test target just import your target using: @testable import MyApp

4. Do this for every file in your project.

Then code coverage will be working fine.

As @Gerd Castan mentioned earlier is: "So it appears to me that a tested method shows a coverage of 0 when there exists at least one target where this method is not tested."

Solution is simple. Do not let compiler think that this file is included in more that one target, instead import your module using @testable keyword.
