Question

我想创建单元测试以确保程序集的配置对某些键具有正确的值。

程序集声明它的配置如下：

- (id)config
{
    return [TyphoonDefinition configDefinitionWithName:@"SomeConfigFile.plist"];
}

并设置一些对象的属性，如下所示：

[initializer injectParameterWith:TyphoonConfig(@"some.config.key")];

我想用正确的钥匙检查装配是否正确，我。即像这样（伪代码）：

assertEquals([myAssembly configValueForKey:@"some.config.key"], @"correct key value");

如何实现这一目标？

我们建议您在从Typhoon发出对象后为其创建集成测试。其中一个测试是对象处于所需的初始状态：

@implementation MyTestCase
{
    TyphoonBlockComponentFactory *_factory;
}

- (void)setUp
{    

    //Recommend putting this in a common place, so main test assembly only has to be set up once
    _factory = [[TyphoonBlockComponentFactory alloc] initWithAssemblies:@[
        [ApplicationAssembly assembly],
        [CoreComponents assembly],
        [PersistenceComponents assembly],
        [NetworkComponents assembly]
    ]];

    TyphoonConfigPostProcessor *postProcessor = [[TyphoonConfigPostProcessor alloc] init];
    [postProcessor useResourceWithName:@"Config.plist"];

    [factory attachPostProcessor:postProcessor];

}

//Assuming a classroom configured with a teacher count from Config.plist
- (void)test_classroom_should_initially_have_one_teacher
{
    CoreComponents *components = [factory asAssembly];
    ClassRoom *classRoom = [factory classroom]; 

    XCTAssertEquals(1, classroom.numberOfTeachers);

}

。。。从这里开始，您可以继续为组件编写其他集成测试。

这是关于integration testing in Typhoon的指南。
您可以测试TyphoonConfig管道，但测试由程序集构建的对象侧重于需求（BDD），并提供程序集所有方面的隐式覆盖。

如何检查Typhoon程序集配置是否包含某些键的值？
