I'm learning to write test cases in iOS with Swift. I was stuck when testing static Functions of mine Utilities Class, so I tried to mock this class and then test the cases. Please let me know if it's the right approach or tell me how to do it. Here is my code:

import XCTest
@testable import ConnectAndSell

class UtilitiesMock{
    func getBuildNumber() -> String{
        return Utilities.getAppBuildNumber()
    }
    func getVersionNumber() -> String{
        return Utilities.getAppVersion()
    }
}

class UtilitiesTests: XCTestCase {
    //system under test
    var sut:UtilitiesMock!

    override func setUp() {
        super.setUp()
        // Put setup code here. This method is called before the invocation of each test method in the class.
        sut = UtilitiesMock()
    }

    override func tearDown() {
        // Put teardown code here. This method is called after the invocation of each test method in the class.
        super.tearDown()
        sut = nil
    }

    func testBuildNumber() {
        let buildNumber = Bundle.main.infoDictionary?("CFBundleVersion") as! String
        XCTAssertEqual(buildNumber, sut.getBuildNumber())

    }

    func testVersionNumber() {
        let versionNumber = Bundle.main.infoDictionary?("CFBundleShortVersionString") as! String
        XCTAssertEqual(versionNumber, sut.getVersionNumber())
    }

}
