XCTEST, NIB & MKMAPVIEW가있는 ViewController

Question

내지도가 내가 제공하는 위치 매개 변수를 보여주고 있는지 테스트하려고합니다. 뷰 컨트롤러에 펜촉을 사용하고 있습니다 (스토리 보드가 싫어).

내가 겪는 문제는 내 맵이 내 테스트에서 나쁘다는 것입니다. 맵은 NIB에서 초기화되어 현재 코드에서 초기화되지 않습니다. 뷰 콘트롤러로 펜촉을 초기화하려고 시도했지만 XCTest에서는 작동하지 않습니다.

#import <XCTest/XCTest.h>
#include "HomeVC.h"

@interface homeVCTests : XCTestCase {
    HomeVC* homeVC;
}

@end

@implementation homeVCTests

- (void)setUp
{
    [super setUp];

    homeVC = [[HomeVC alloc] initWithNibName:@"HomeVC" bundle:nil];
    [homeVC viewDidLoad];
}

- (void)tearDown
{
    [super tearDown];
}

- (void)testHomeHasMap // Fails
{
    XCTAssertNotNil(homeVC.map, @"Map is not nil.");
}

- (void)testHomeHasMapTypeHybrid // Fails
{
    XCTAssertEqual(homeVC.map.mapType, MKMapTypeHybrid, @"Map type is hybrid(2)");
}

- (void)testHomeHasMapWithMyLocation // Fails
{
    [homeVC setMapCurrentLocation:37.785834 lon:-122.406417];
    CLLocationCoordinate2D checkpoint = CLLocationCoordinate2DMake(37.785834, -122.406417);
    XCTAssertEqual(homeVC.map.centerCoordinate.latitude, checkpoint.latitude, @"Map shows my location.");
}

비동기 메소드를 구현하는 뷰 컨트롤러에 대해 이와 같은 단위 테스트를하는 것은 불가능합니다. 테스트 방법이 즉시 실행되므로 결과를 볼 수 없습니다. 주정부가 요구 사항을 충족 할 때까지 세마포어 또는 기타 기술을 사용하여 Runloop를 일시 중지 할 수 있습니다.
