Same as in the other review, can we test changing all parts that contribute to the hash?

let c2 = URLComponents(string: "https://www.swift.org/path/to/file.html?id=name")!

XCTAssertEqual(c1, c2)
XCTAssertEqual(c1.hashValue, c2.hashValue)
}

func test_createURLWithComponents() {
let urlComponents = NSURLComponents()
urlComponents.scheme = "https";
