Question

When i run unit tests it fails on loading external resources (images) with the same error as if they don’t exist. In xcode i have added the resources to the unit test target. I don’t know what to try next.

I am using the Cocos2d framework, I try to load the following code within a unit test

AtlasSpriteManager *at = [AtlasSpriteManager spriteManagerWithFile:@"player2.png" capacity:50];


It seems this actually calls

UIImage imageWithContentsOfFile

which returns nil.

The actual code that throws the error looks like

image = [uiImage CGImage];
if(image == NULL) {
[self release];
NSLog(@"Image is Null");
return nil;
}

It seems that the images required are not copied over to the Application Support directory before the unit tests run, only after a successful pass. I am not sure if this is the problem, but if it is is there a way to change the build order so the images are copied first and the unit tests can find them?

The resources most likely aren’t getting included into the target. So before you have your Run Script phase of your test bundle, make sure you have a “Copy Resources” phase that copies the resources into the test bundle that the tests will need.
