NSURL to file path in test bundle with XCTest

Question

I am trying to write an iOS app using TDD and the new XCTest framework. One of my methods retrieves a file from the internet (given a NSURL object) and stores it in the user

Answer 1

1. You can reference bundle files like in any target.
2. Check if the file is Copyed in the Copy Bundle Resources build phase (of your test target)

3. To access to the local file :

   NSURL*imageUrl=[[NSBundle mainBundle]URLForResource:@"imageName" withExtension:@"png"];
   

You can make asynchronous access and wait for the response using : https://github.com/travisjeffery/TRVSMonitor

If you have added : dataset1.json in the test target (2) :

NSString *p=[[NSBundle mainBundle] pathForResource:@"dataset1" ofType:@"json"];
NSLog(@"%@",p);

Answer 2

In fact, the [NSBundle mainBundle] when running a UnitTest is not the path of your app, but is /Developer/usr/bin, so this will not work.

The way to get resources in a unit test is here: OCUnit & NSBundle

In short, use:

[[NSBundle bundleForClass:[self class]] resourcePath]

or in your case:

[[NSBundle bundleForClass:[self class]] resourceURL]
