我按照苹果开发者页面 – Automated Unit Testing with
Xcode 3 and Objective-C上的步骤.当我添加了我的第一个测试,当测试失败时,它工作正常,但是当我更正测试时,构建失败. Xcode报告以下错误：

error: Test host ‘/Users/joe/Desktop/OCT/build/Debug/OCT.app/Contents/MacOS/OCT’ exited abnormally with code 138 (it may have crashed).

试图隔离我的错误,我重新遵循上面的单元测试示例中的步骤,并且示例工作.当我添加了我的代码和测试用例的简化版本时,返回错误.

这是我创建的代码：

Card.h

#import <Cocoa/Cocoa.h>
#import "CardConstants.h"
 
@interface Card : NSObject {
    int rank;
    int suit;
    BOOL wild ;
}
 
@property int rank;
@property int suit;
@property BOOL wild;
 
- (id) initByIndex:(int) i;
 
@end

Card.m

#import "Card.h"
 
@implementation Card
 
@synthesize rank;
@synthesize suit;
@synthesize wild;
 
- (id) init {
    if (self = [super init]) {
        rank = JOKER;
        suit = JOKER;
        wild = false;
    }
    return [self autorelease];
}
 
- (id) initByIndex:(int) i {
    if (self = [super init]) {
        if (i > 51 || i < 0) {
            rank = suit = JOKER;
        } else {
            rank = i % 13;
            suit = i / 13;
        }
        wild = false;
    }
    return [self autorelease];
}
 
- (void) dealloc {
    NSLog(@"Deallocing card");
    [super dealloc];
}
 
@end

CardTestCases.h

#import <SenTestingKit/SenTestingKit.h>
 
@interface CardTestCases : SenTestCase {
}
- (void) testInitByIndex;
@end

CardTestCases.m

#import "CardTestCases.h"
#import "Card.h"
 
@implementation CardTestCases
 
- (void) testInitByIndex {
    Card *testCard = [[Card alloc] initByIndex:13];
    STAssertNotNil(testCard,@"Card not created successfully");
    STAssertTrue(testCard.rank == 0,@"Expected Rank:%d Created Rank:%d",testCard.rank);
    [testCard release];
}
@end
