是否有更好的方法来比较我的模型对象中的值,而不是下面的代码片段,它看起来非常详细,而且只针对一个属性?
模型对象
struct Address {
static let kADDRESS1 = "address1"
static let kADDRESS2 = "address2"
static let kADDRESS3 = "address3"
static let kCITY = "city"
static let kSTATE = "state"
static let kPOSTAL_CODE = "postalCode"
var address1:String?,
address2:String?,
address3:String?,
city:String?,
state:String?,
postalCode:String?
init(address1: String?,
address2: String?,
address3: String?,
city: String?,
state: String?,
postalCode: String?) {
self.address1 = address1;
self.address2 = address2;
self.address3 = address3;
self.city = city;
self.state = state;
self.postalCode = postalCode;
}
init(params:NSDictionary) {
self.init(address1: params.objectForKey("address1") as String?,
address2: params.objectForKey("address2") as String?,
address3: params.objectForKey("address3") as String?,
city: params.objectForKey("city") as String?,
state: params.objectForKey("state") as String?,
postalCode: params.objectForKey("state") as String?)
}
}
来自测试用例 func testCreateAddress(){
let params:NSDictionary = [Address.kADDRESS1: "1 Main St.", Address.kADDRESS2: "Apt. 1", Address.kADDRESS3: "Box 1", Address.kCITY: "San Francisco", Address.kSTATE: "CA", Address.kPOSTAL_CODE: "7899"];
let address = Address(params:params);
if let param = params[Address.kADDRESS1] as String? {
if let property = address.address1 {
XCTAssertEqual(property, param)
}
else {
XCTFail("properties do not match")
}
}
else {
if let property = address.address1 {
XCTFail("properties do not match")
}
}
}

我认为你可以在测试中假设一些事情:
XCTAssertEqual
会让您的测试失败(出现相应的错误
消息)如果字符串不相等,因此您不需要任何XCTFail
params[Address.kADDRESS1]
肯定是您刚刚定义的
上述
所以我建议将测试改为:
let params:NSDictionary = [Address.kADDRESS1: "1 Main St.", Address.kADDRESS2: "Apt. 1", Address.kADDRESS3: "Box 1", Address.kCITY: "San Francisco", Address.kSTATE: "CA", Address.kPOSTAL_CODE: "7899"]
let address = Address(params:params)
XCTAssertNotNil(address.address1)
XCTAssertEqual(address.address1!, params[Address.kADDRESS1], "address1 should be set")
我承认,如果address.adress1
为nil,您将获得运行时异常,因为XCTAssertEqual
将无法解包该变量,但XCTAssertNotNil
将事先失败,因此您知道& #39;正在发生。

我想我发现了一种更简洁的方式:
if(address.address1? != nil && params[Address.kADDRESS1]? != nil) {
XCTAssertEqual(address.address1!, params[Address.kADDRESS1]!)
}
