ios - 如何快速读取 JSON.text 文件以生成数据类型？

Question

我想模拟一个网络结果数据并在JSON.txt中模拟它，我想进行json解析的单元测试但是我似乎总是无法读取JSON.txt文件

将要测试的方法:

class Music {


    func parseJSON(data : Data) -> [[String:Any]]? {

        return try? JSONSerialization.jsonObject(with: data, options: []) as! [[String:Any]]
    }
}

这是测试用例

import XCTest
@testable import basicUnitTesting

class musicTests: XCTestCase {


    func testParseJSON() {
        let music = Music()
        let bundle = Bundle(for: type(of: self))
        if let path = bundle.path(forResource: "JSON", ofType: "txt") {
            if let data = try? Data.init(contentsOf: URL.init(fileURLWithPath: path)) {
                let result = music.parseJSON(data: data)

                XCTAssertNotNil(result, "It should not be nil")
                XCTAssertGreaterThan(result!.count, 0, "It should have value, not zero")
            } else {
                XCTFail()
            }

        } else {
            XCTFail()
        }

    }



}

错误截图如下:

如您所见，路径为 nil，然后测试失败。

Answer 1

从错误中可以清楚地看出您的文件未包含在资源路径中错误行 > if let path = bundle.path(forResource: "JSON", ofType: "txt")

因此，问题是您的文件未包含在此处 musicTests > Build Phases > Copy Bundle Resources
