在路径 SPM swift 中获取文件

Question

我在 SPM 中有一个包，我正在处理文件系统。我现在面临的问题是当我尝试获取 json 文件之类的文件时，我的测试用例失败了。这是我的代码和测试用例。

MT测试

func testBundle() -> Bundle? {
        return Bundle(for: LandingPageSerializationTests.self)
    }
    
    func parseLandingPage(fromFile filename: String?) -> LandingPage? {
        let path = testBundle()?.path(forResource: filename, ofType: nil, inDirectory: kConfigFileFolder)
        XCTAssertNotNil(path)
        
        let data = NSData(contentsOfFile: path) as Data?
        XCTAssertNotNil(data)
        
        var asDict: [String: Any]? = nil
        do {
            if let data = data {
                asDict = try JSONSerialization.jsonObject(with: data, options: []) as? [String : Any]
            }
        } catch {
        }
        XCTAssertNotNil(asDict)
        
        return LandingPageSerialization.landingPage(fromJson: asDict)
    }

我的Package.swift

let package = Package(
    name: "XXXX",
    platforms: [.iOS(.v11)],
    products: [
        // Products define the executables and libraries a package produces, and make them visible to other packages.
        .library(
            name: "XXXX",
            targets: ["XXXX"]),
    ],
    dependencies: [
        // Dependencies declare other packages that this package depends on.
    ],
    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: "XXXX",
            dependencies: [
            ],
            resources: [
                .process("Resources"),
            ]
        ),
        .testTarget(
            name: "XXXXTests",
            dependencies: ["XXXX"],
            resources: [
                .process("Resources"),
            ]
        ),

    ]
)

我不知道为什么尽管提到了特定的名称，但我的路径总是得到 nil。

行

resources: [
    .process("Resources"),
]

如果这是一个名为 Resources 的文件，那就对了。如果 Resources 是一个文件夹，您需要 .copy，而不是 .process。

此外，我认为您无法按照您尝试的方式从包的测试目标包中获取资源。您需要从包的主要目标包中获取它，您可以说 Bundle.module.

这是一个演示。这是我的包裹的结构：

这是我的包裹声明：

let package = Package(
    name: "XXXXX",
    products: [
        .library(
            name: "XXXXX",
            targets: ["XXXXX"]),
    ],
    dependencies: [
    ],
    targets: [
        .target(
            name: "XXXXX",
            dependencies: [],
            resources: [.copy("Resources")]),
        .testTarget(
            name: "XXXXXTests",
            dependencies: ["XXXXX"]),
    ]
)

这是一个有效的测试方法：

func testExample() throws {
    let b = Bundle.module
    let url = b.url(forResource: "test", withExtension: "json", subdirectory: "Resources")
    let urlreal = try XCTUnwrap(url)
    let data = try Data(contentsOf: urlreal)
    let result = try JSONSerialization.jsonObject(with: data, options: [])
    let resultreal = try XCTUnwrap(result as? [String:Any]) // dictionary
    XCTAssertEqual(resultreal["name"] as? String ?? "", "Matt")
}
