how to read JSON.text file to produce data type in swift?

I am a junior iOS Developer, and I am trying to mock a networking result data and mock it in the JSON.txt, I want to perform unit test of json parsing but it seems that I always failed to read the JSON.txt file

the method that will be tested:

class Music {


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

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

and here is the testCase

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()
        }

    }



}

and here is the screenshot of the error:

as you can see, the path is nil and then the test failed.

and here is the data inside the JSON.txt to mock the data
