对象的单元测试

Question

我是目标 c 的学习者，并且开始进行单元测试，

我想在对象下面进行单元测试

@interface Media : NSObject{

}
@property (nonatomic, readonly) NSString *name;
@property (nonatomic, readonly) NSString *sex;
@property (nonatomic, readonly) NSString *Description;

- (instancetype)initWithDictionary:(NSDictionary *)mediaData;

@end

#import "Media.h"

@interface Media()

@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) NSString *sex;
@property (nonatomic, strong) NSString *Description;

@end

@implementation Media

- (instancetype)initWithDictionary:(NSDictionary *)mediaData
{
    self = [super init];
    if (self)
    {
        _name; = mediaData[Name];//getting from Json
        _sex = mediaData[Sex];
        _description = mediaData[Description];
    }
    return self;
}
@end

我的测试课

#import <UIKit/UIKit.h>
#import <XCTest/XCTest.h>
#import "Media.h"

@interface ModelUnitTest : XCTestCase

@end

@implementation ModelUnitTest

- (void)setUp {
    [super setUp];
    // Put setup code here. This method is called before the invocation of each test method in the class.
}

- (void)tearDown {
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    [super tearDown];
}

- (void)testModelObject:(id)file
{
    XCTAssertNotNil(file);
    XCTAssertTrue(file isKindOfClass:[Media class]]);
    Media * fileObj = (Media *)file;
    XCTAssertNotNil(fileObj.name);
    XCTAssertNotNil(fileObj.sex);
    XCTAssertNotNil(fileObj.description);
}

但是，这个测试永远不会运行 我知道我在这里犯了一些错误我错过了一些东西但无法弄清楚在这种情况下谁能帮助我

Xcode 只会运行方法签名以您拥有的“test”开头的测试，但方法签名也可以没有参数。如果您将方法名称更改为

，测试将运行

- (void)testModelObject
{

}

但这意味着您将不再拥有您的file。您应该在方法中或在 setup 方法中初始化它，如下所示：

@interface ModelUnitTest : XCTestCase
@property (nonatomic, strong) id file;
@end

@implementation ModelUnitTest

- (void)setUp {
[super setUp];
self.file = //setup your file
}

- (void)tearDown {
    // tear down your file if necessary
    [super tearDown];
}

- (void)testModelObject
{
    XCTAssertNotNil(self.file);
    XCTAssertTrue(self.file isKindOfClass:[Media class]]);
    Media * fileObj = (Media *)self.file;
    XCTAssertNotNil(fileObj.name);
    XCTAssertNotNil(fileObj.sex);
    XCTAssertNotNil(fileObj.description);
 }
