用台风注入模拟 [英] Injecting mock with Typhoon

问题描述

我正在尝试编写XCTest并使用Typhoon注入模拟的依赖项.

I'm trying to write XCTest and inject mocked dependency with Typhoon.

这是我的ViewController中的代码:

   - (instancetype)init {
    self = [super init];

    MDMainAssembly *assembly = (MDMainAssembly *) [TyphoonComponentFactory defaultFactory];
    self.alertManager = [assembly alertManager];

    return self;
   }

这是我要更改注射方式的方法:

Here is how I'm trying to change injection:

    self.mockedAlertManager = mock([MDAlertManager class]);

    MDMainAssembly *assembly = [MDMainAssembly assembly];
    TyphoonComponentFactory *factory = [TyphoonBlockComponentFactory factoryWithAssembly:assembly];
    TyphoonPatcher *patcher = [[TyphoonPatcher alloc] init];
    [patcher patchDefinition:[assembly alertManager] withObject:^id {
        return self.mockedAlertManager;
    }];

    [factory attachPostProcessor:patcher];

但是，由于无法将此工厂设置为默认值，因此测试失败.我在AppDelegate工厂中配置:

However tests are failing because this factory not possible to set as default. I configure in AppDelegate factory:

    TyphoonComponentFactory *factory = [[TyphoonBlockComponentFactory alloc] initWithAssemblies:@[
        [MDMainAssembly assembly],
    ]];
    [factory makeDefault];

如何摆脱这种情况?

推荐答案

我们为有限的情况创建了defaultFactory功能.主要是:

We created the defaultFactory feature for a limited number of cases. The main is:

• 访问Typhoon并查找非Typhoon管理的类的依赖关系.通常，这不是必需的.

尽管您可以在测试中使用它，但我们建议您为每次测试运行创建并销毁Typhoon容器.为避免重复，您可以创建如下方法:

Although you could use it in tests, we recommend instead creating and destroying a Typhoon container for each test run. To avoid duplication, you could create a method as follows:

@implementation IntegrationTestUtils

+ (TyphoonComponentFactory*)testAssembly
{
    TyphoonComponentFactory* factory = [[TyphoonBlockComponentFactory alloc] initWithAssemblies:@[
        [MyAppAssembly assembly],
        [MyAppKernel assembly],
        [MyAppNetworkComponents assembly],
        [MyAppPersistenceComponents assembly]
    ]];

    id <TyphoonResource> configurationProperties = [TyphoonBundleResource withName:@"Configuration.properties"];
    [factory attachPostProcessor:[TyphoonPropertyPlaceholderConfigurer configurerWithResource:configurationProperties]];

    return factory;
}

. .如果需要，您可以将修补器连接到此装配件.

. . if required you could attach a patcher to this assembly.

将修补程序附加到默认工厂:

如果要将修补程序应用于默认程序集，则很可能要再次取消修补程序.此功能位于积压的此处.

If you were to apply a patcher to the default assembly, you'd most probably want to un-patch again. This feature is in the backlog here.
