OCUnit & NSBundle
- by kpower
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];
}
[path release];
}
return self;
}
- (void)dealloc {
[image release];
[super dealloc];
}
@end
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
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
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).
What's wrong?
