我根据“iPhone 开发指南”创建了 OCUnit 测试。这是我要测试的课程:
// myClass.h
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface myClass : NSObject {
UIImage *image;
}
@property (readonly) UIImage *image;
- (id)initWithIndex:(NSUInteger)aIndex;
@end
// myClass.m
#import "myClass.m"
@implementation myClass
@synthesize image;
- (id)init {
return [self initWithIndex:0];
}
- (id)initWithIndex:(NSUInteger)aIndex {
if ((self = [super init])) {
NSString *name = [[NSString alloc] initWithFormat:@"image_%i", aIndex];
NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"png"];
image = [[UIImage alloc] initWithContentsOfFile:path];
if (nil == image) {
@throw [NSException exceptionWithName:@"imageNotFound"
reason:[NSString stringWithFormat:@"Image (%@) with path \"%@\" for current index (%i) wasn't found.",
[name autorelease], path, aIndex]
userInfo:nil];
}
[name release];
}
return self;
}
- (void)dealloc {
[image release];
[super dealloc];
}
@end
我的单元测试(LogicTests 目标):
// myLogic.m
#import <SenTestingKit/SenTestingKit.h>
#import <UIKit/UIKit.h>
#import "myClass.h"
@interface myLogic : SenTestCase {
}
- (void)testTemp;
@end
@implementation myLogic
- (void)testTemp {
STAssertNoThrow([[myClass alloc] initWithIndex:0], "myClass initialization error");
}
@end
所有必要的框架、“myClass.m”和添加到目标的图像。但是在构建时我有一个错误:
[[myClass alloc] initWithIndex:0] raised Image (image_0) with path \"(null)\" for current index (0) wasn't found.. myClass initialization error
此代码(初始化)在应用程序本身(主要目标)中运行良好,稍后显示正确的图像。我还检查了我的项目文件夹 ( build/Debug-iphonesimulator/LogicTests.octest/
) - 有LogicTests
,Info.plist
和必要的图像文件 (image_0.png
是其中之一)。
怎么了?
