Question

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 website上显示的相同。当我在控制台中调用 swift build 然后快速测试时，我收到以下错误：

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

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 并输入 swift build 然后 swift test 时，我会收到以下错误：

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包generate-xcodeproj ）然后我得到编译错误：

没有测试文件，一切正常。下面我介绍项目结构：

Answer 1

我认为问题是Swift无法为包含main.swift文件的模块编译单元测试（即，要编译为可执行文件的模块，而不是用于其他项目的库）。我克隆了你的repo，并且能够在1）删除main.swift和2）取消注释testable import语句之后编译并运行单元测试。

在Kitura中运行单元测试时出错
