单元测试的Xcode 9代码覆盖率显示错误百分比

Question

The Code Coverage report generated by XCode 9 seems to be off on some files in my project. It shows 0% in one of the class file While when I check the codes it actually covered by the test

It looks like that the coverage report is actually in-sync with the tests???

Environment: Xcode 9.2 Swift 4

Answer 1

I believe you'll find the answer here Code coverage result is not accurate to real coverage in Xcode 7

Briefly it says to use

@testable import <yourapp>

In each test file and don't add your app .swift files to the test targets.

Works for me.
