用Swift语言做App开发之单元测试

　　创建完成后，导入XCTest框架，并使该类继承自XCTestCase，然后录入测试代码：
import XCTest
class UrlTests: XCTestCase {
var urlInstance = Url(baseUrl: "http://localhost:8080/api/")
func testShouldGetCorrectPathWhenNoSegmentProvided() {
let resourcePath = "customers"
let result = urlInstance.getActualPathFrom(resourcePath， segments: [String:String]())
XCTAssertEqual(result， "http://localhost:8080/api/customers"， "Can not get corrent path when no segments provided")
}
func testGetCorrectPathGivenOneSegment() {
let resourcePath = "customer/{id}"
let result = urlInstance.getActualPathFrom(resourcePath， segments: ["id": "10"]);
XCTAssertEqual(result， "http://localhost:8080/api/customer/10"， "Can not get corrent path when only one segment provided")
}
}
　　后Command＋U执行测试
