使用 Swift 包管理器时在测试目标之间共享代码

Sharing code across test targets when using the Swift Package Manager

我有一些代码需要在测试目标之间共享,同时我正在使用 Swift 包管理器。为此,我有一个 .testTarget,我也将其命名为另一个 .testTarget 中的依赖项。

这是一个简单的例子:

// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "ExampleLib",
    products: [
        // Products define the executables and libraries a package produces, and make them visible to other packages.
        .library(
            name: "ExampleLib",
            targets: ["ExampleLib"]),
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
        // .package(url: /* package url */, from: "1.0.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package. A target can define a module or a test suite.
        // Targets can depend on other targets in this package, and on products in packages this package depends on.
        .target(
            name: "ExampleLib",
            dependencies: []),
        .testTarget(
            name: "Common",
            dependencies: ["ExampleLib"]),
        .testTarget(
            name: "ExampleLibTests",
            dependencies: ["Common"]),
            
    ]
)

如果我尝试在 Xcode 中构建此包,我会收到以下错误:

Unable to resolve build file: XCBCore.BuildFile (The workspace has a reference to a missing target with GUID 'PACKAGE-TARGET:Common')

但是,如果我从命令行构建 (swift build) 或从命令行测试 (swift test),我会成功。

我正在使用 Xcode 12 beta 6,但也尝试了 Xcode 11.5(对 Package.swift header 进行了更改)并获得了相同的结果.

我真的很想在 Xcode 中使用它来构建 iOS。想法?

我遇到了同样的问题并通过为 Common.

定义 Target(不是测试目标)解决了这个问题

我的 Package.swift 文件:

// ...
.target(name: "Common", dependencies: ["App"], path: "Tests/Common"),
.testTarget(name: "AppTests", dependencies: ["App", "Common"]),
.testTarget(name: "IntegrationTests", dependencies: ["App", "Common"])
// ...
