OCUnit& NSBundle [英] OCUnit & NSBundle

问题描述

我根据《 iPhone开发指南》创建了OCUnit测试.这是我要测试的课程:

I created OCUnit test in concordance with "iPhone Development Guide". Here is the class I want to test:

// 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

还有我的单元测试(LogicTests目标):

And my unit-test (LogicTests target):

// 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

所有必需的框架，"myClass.m"和添加到目标的图像.但是在构建时我有一个错误:

All necessary frameworks, "myClass.m" and images added to target. But on build I have an error:

[[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)中正常工作，并在以后显示正确的图像.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).

This code (initialization) works fine in application itself (main target) and later displays correct image. I've also checked my project folder (build/Debug-iphonesimulator/LogicTests.octest/) - there are LogicTests, Info.plist and necessary image files (image_0.png is one of them).

怎么了?

推荐答案

仅为此问题找到了一种解决方案.

Found only one solution for this problem.

构建单元测试时，主捆绑包的路径与项目捆绑包(创建的.app文件)不同.而且，它不等于LogicTests捆绑软件(创建的LogicTests.octest文件).

When I build my unit-tests, the main bundle's path is not equal to my project's bundle (created .app file). Moreover, it's not equal to LogicTests bundle (created LogicTests.octest file).

用于单元测试的主捆绑包类似于/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.3.sdk/Developer/usr/bin.这就是程序无法找到必要资源的原因.

Main bundle for unit-tests is something like /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.3.sdk/Developer/usr/bin. And that's why program can't find necessary resources.

最后的解决方案是获取直接捆绑包:

And the final solution is to get direct bundles:

NSString *path = [[NSBundle bundleForClass:[myClass class]] pathForResource:name ofType:@"png"];

代替

NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:@"png"];
