Objective c OCMock测试通过的块是否正确执行

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
[self updatePostalCode:newLocation withHandler:^(NSArray *placemarks, NSError *error) {
// code that want to test
CLPlacemark *placemark = [placemarks objectAtIndex:0];
self.postalCode = [placemark postalCode];
_geocodePending = NO;
}];
....
}
我想知道postalCode的设置是否正确,但我不知道如何使用OCMock实现这一点
添加代码
id mockSelf = [OCMockObject partialMockForObject:_location];
id mockPlacemart = (id)[OCMockObject mockForClass:[CLPlacemark class]];
[[[mockPlacemart stub] andReturn:@"10170"] postalCode];
[mockSelf setGeocodePending:YES];
[mockSelf setPostalCode:@"00000"];
[self.location handleLocationUpdate]([NSArray arrayWithObject:mockPlacemart], nil);
STAssertFalse([mockSelf geocodePending], @"geocodePending should be FALSE");
STAssertTrue([[mockSelf postalCode] isEqualToString:@"10170"], @"10170", @"postal is expected to be 10170 but was %@" , [mockSelf postalCode]);
从类上的方法返回处理程序块,包括可测试性
- (void (^)(NSArray *, NSError *))handleLocationUpdate {
__weak Foo *weakself = self;
return ^(NSArray *placemarks, NSError *error) {
CLPlacemark *placemark = [placemarks objectAtIndex:0];
weakself.postalCode = [placemark postalCode];
weakself.geocodePending = NO;
}
}
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
[self updatePostalCode:newLocation withHandler:[self handleLocationUpdate]];
....
}
然后,在测试中:
-(void)testLocationUpdates {
id mockPlacemark = [OCMockObject mockForClass:[CLPlacemark class]];
[[[mockPlacemark stub] andReturn:@"99999"] postalCode];
myClass.geocodePending = YES;
myClass.postalCode = @"00000";
[myClass handleLocationUpdate]([NSArray arrayWithObject:mockPlacemark], nil);
expect(myClass.geocodePending).toBeFalsy;
expect(myClass.postalCode).toEqual(@"99999");
}
感谢这篇文章完美地解释了它背后的智慧,但我不理解
[myClass handleLocationUpdate]([NSArray arrayWithObject:mockPlacemark],无)代码>和从不看expect()。到…
我可以参考这些吗?我把我的代码复制到了你的问题中,我明白了吗?如果你定义了所列的方法,那么[myClass handleLocationUpdate]
返回块。您正在将块作为函数执行,并传入包含模拟的placemarks数组。expect()
来自Pete Kim的优秀matcher框架。我们在所有项目中都使用它。松耦合“self”的一个好例子需要在返回块的方法中很弱。
