单元测试CLLocationManager的实现 [英] Unit Test CLLocationManager implementation

问题描述

我有一个名为 GeolocationManager 的类，该类处理 CLLocationManager 对象和 delegate 响应。

I have a class named "GeolocationManager" that handles a CLLocationManager object and delegate responses.

- (void)getGeolocationForClient:(id<GeolocationManagerDelegate>)client
{
    _delegate = client;
    _locationManager = [self createLocationManager];
    _locationManager.delegate = self;
    _locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters;
    [_locationManager startUpdatingLocation];
}

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
   // do some stuff
}

createLocationManager是一个公共方法，随时可以进行存根

createLocationManager is a public method ready to be stubbed

- (CLLocationManager *)createLocationManager
{
    return [[CLLocationManager alloc] init];
}

我要实现的目标是测试用户拒绝地理定位时， CLLocationManagerDelegate 方法 locationManager：didFailWithError：在我的 GeolocationManager 上被调用对象。

What I want to achieve is to test that when user denies being geolocated the CLLocationManagerDelegate method locationManager:didFailWithError: is being called on my GeolocationManager object.

下面的测试方法似乎无效

My test method below does not seem to be working

- (void)testOnUserDenial
{
    GeolocationManager *geolocationManager = [[GeolocationManager alloc] init];
    id geolocationManagerTest = [OCMockObject partialMockForObject:geolocationManager];

    CLLocationManager *locationManager = [[CLLocationManager alloc] init];
    id locationManagerTest = [OCMockObject partialMockForObject:locationManager];

    [[[locationManagerTest stub] andReturnValue:@(kCLAuthorizationStatusDenied)] authorizationStatus];
    [[[geolocationManagerTest stub] andReturn:locationManagerTest] createLocationManager];

    [[geolocationManagerTest expect] locationManager:[OCMArg any] didFailWithError:[OCMArg any]];

    [geolocationManagerTest getGeolocationForClient:[OCMArg any]];

    [geolocationManagerTest verify];
}

名称：NSInternalInconsistencyExceptionException文件：未知行：未知
原因：OCPartialMockObject [GeolocationManager]：未调用预期方法
：locationManager：OCPartialMockObject [CLLocationManager]
didFailWithError：

Name: NSInternalInconsistencyException File: Unknown Line: Unknown Reason: OCPartialMockObject[GeolocationManager]: expected method was not invoked: locationManager:OCPartialMockObject[CLLocationManager] didFailWithError:

推荐答案

您是否尝试过使用 OCMOCK_VALUE（kCLAuthorizationStatusDenied）作为returnValue？

Have you tried using OCMOCK_VALUE(kCLAuthorizationStatusDenied) for the returnValue?
