我正在尝试测试我的地图是否显示了我提供的位置参数。我正在为我的视图控制器使用 Nib（我讨厌故事板）。
我遇到的问题是我的地图在我的测试中为零。地图在 Nib 中初始化，并没有在我当前的代码中初始化。我尝试用我的 ViewController 初始化我的 Nib，但这似乎在 XCTest 中不起作用。
#import <XCTest/XCTest.h>
#include "HomeVC.h"
@interface homeVCTests : XCTestCase {
HomeVC* homeVC;
}

{
[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)");
}

{
[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.");
