我是 Kitura 和 Xcode 的新手，在添加测试文件时遇到了一些问题。它似乎与@testing 指令有关。我的设置与Kitura 网站上显示的相同。当我在控制台中调用swift build然后swift test我得到以下错误：

Compile Swift Module 'testTests' (1 sources)
Linking ./.build/debug/testPackageTests.xctest/Contents/MacOS/testPackageTests
Undefined symbols for architecture x86_64:
  "__TFC4test3OkoCfT_S0_", referenced from:
      __TFC9testTests8OkoTests8test_addfT_T_ in OkoTests.swift.o
  "__TMaC4test3Oko", referenced from:
      __TFC9testTests8OkoTests8test_addfT_T_ in OkoTests.swift.o
ld: symbol(s) not found for architecture x86_64
<unknown>:0: error: link command failed with exit code 1 (use -v to see invocation)

error: exit(1): /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-build-tool -f /Users/*user*/Projects/Kitura/test/.build/debug.yaml test

但是，当我注释掉@testable import test行并键入swift build然后swift test时，我收到以下错误：

Compile Swift Module 'testTests' (1 sources)
/Users/*user*/Projects/Kitura/test/Tests/testTests/OkoTests.swift:6:17: error: use of unresolved identifier 'Oko'
        let o = Oko()

当我尝试从 Xcode 生成的项目中测试它时（swift package generate-xcodeproj）然后我得到编译错误：

Xcode 构建错误

没有测试文件，一切正常。下面我介绍项目结构：

我认为问题在于 Swift 无法为包含main.swift文件的模块编译单元测试（即，旨在编译为可执行文件的模块，而不是用于其他项目的库）。我克隆了您的存储库，并且能够在 1）删除main.swift和 2）取消注释可测试的导入语句后编译和运行单元测试。
