Objective C使用Swift代码测试类 [英] Objective C test class using Swift code

问题描述

我在 MyProjectName 文件夹中有一个swift协议 IModelIdProvider 。
我在 MyProjectNameTests 文件夹中创建了一个名为 RemoteModelFactoryTest 的objective-c单元测试类。
要进行一些测试， RemoteModelFactoryTest 必须实现 IModelIdProvider 协议。

I have a swift protocol IModelIdProvider in the MyProjectName folder. I have created an objective-c unit test class named RemoteModelFactoryTest in the MyProjectNameTests folder. To do some tests, RemoteModelFactoryTest must implement the IModelIdProvider protocol.

当我 #importMyProjectName-Swift.h在我的objective-c类中使用我的swift协议时，我得到找不到文件。

When I #import "MyProjectName-Swift.h" to use my swift protocol in my objective-c class, I get a file not found.

如果我将 #import 指令更改为 #importMyProjectNameTests-Swift.h，找到标题但不是我的协议（它在 MyProjectName 项目中定义，而不是在 MyProjectNameTests 项目中。

If I change the #import instruction to #import "MyProjectNameTests-Swift.h", the header is found but not my protocol (it's defined in the MyProjectName project, not in the MyProjectNameTests project).

在中有什么特别的事吗？ *测试使用Swift代码的项目？

Is there something special to do in the *Tests projects to use Swift code ?

推荐答案

我知道它的额外hacky和一切，但是什么我做了，它的工作原理是从生成的Project-Swift.h复制公共标题并粘贴 .m 测试文件所需的内容。

I know its extra hacky and everything, but what I did and it worked was to copy public headers from generated "Project-Swift.h" and paste whats needed to .m file of test.

所以我复制了这样的东西：

So I copied something like this:

SWIFT_CLASS("_TtC10Inventorum11ImageEntity")
@interface ImageEntity : NSObject <FICEntity>
@property (nonatomic, copy) NSString * imageID;
@property (nonatomic) NSURL * retinaImageURL;
@property (nonatomic) NSURL * nonRetinaimageURL;
@property (nonatomic, readonly) NSURL * imageURL;
@property (nonatomic, readonly, copy) NSString * UUID;
@property (nonatomic, readonly, copy) NSString * sourceImageUUID;
@property (nonatomic) RACSignal * rac_signalForImage;
- (instancetype)init OBJC_DESIGNATED_INITIALIZER;
- (NSURL *)sourceImageURLWithFormatName:(NSString *)formatName;
- (FICEntityImageDrawingBlock)drawingBlockForImage:(UIImage *)image withFormatName:(NSString *)formatName;
- (void)objc_setType:(NSString *)type;
@end

除此之外，我还复制了 SWIFT_CLASS 等我的测试正在构建并通过测试Swift代码。

And on top of this I have also copied all the macros for SWIFT_CLASS etc. My tests are building and passing testing Swift code.

BTW。别忘了在Swift中对测试的类和方法进行公开。

BTW. Dont forget to put public on tested classes and methods in Swift.
