When using NSHomeDirectory() inside a unit test I get:

/Users/hgpc/Library/Application Support/iPhone Simulator/5.0

I expected the actual home directory of the current application. Something like:

/Users/hgpc/Library/Application Support/iPhone Simulator/5.0/Applications/6D1091C6-02AE-4803-A7DF-D623D0F89579

What am I doing wrong?

To solve this, set the value of Bundle Loader within your Unit Test target build settings to:

$(BUILT_PRODUCTS_DIR)/MyAppName.app/MyAppName

and also your Test Host to:

$(BUNDLE_LOADER)

you should then find NSHomeDirectory() returns the right value.

  • This seems preferred over the other solutions. Much closer simulation of what's going on. Works equally well on simulator and device. – lyricsboy Oct 25 '12 at 17:06

    Is this the default now? In a fresh project in XCode created with unit tests the UT target's "Bundle Loader" setting matches the above. – Parrots Mar 31 '13 at 17:58

    Yes, it's default now. – Florian Mielke Sep 24 '13 at 07:42

    I need to achieve the same but within the UI tests. Is it possible? Because this works only for unit tests. – Sil May 26 '17 at 12:03

Unfortunately, while in a unit-test (or logic test) - you're not really "in your app" (i.e. its sandbox). That's why stuff like NSDocumentDirectory or [NSBundle mainBundle] will not work.

If it works for you, I'd just go ahead and create a "Documents" folder in 

/Users/hgpc/Library/Application Support/iPhone Simulator/5.0

You might want to do this in your test's setUp, that way you can delete it in tearDown.

If that doesn't work because your tests depend on stuff already being in your app's NSDocumentDirectory, you might want to re-think your test a little, as they should all be self-contained (i.e. install all resources from your bundle in setUp)

You could also use NSLibraryDirectory instead of NSDocumentDirectory, depending on what it is that you want to test.

If you'd like to customised your test target to Application test you should add params mentioned by Andrew Ebling:

$(BUILT_PRODUCTS_DIR)/MyAppName.app/MyAppName

and also your Test Host to:

$(BUNDLE_LOADER)

If you don't have this params that means your tests is logic. But if you add this params you change tests to Application tests and notice that AppDelegate will start did you run tests.

see link for more information.

So you can use NSHomeDirectory( for Application tests only.

On an iOS device you should use

NSArray *path = NSSearchPathForDirectoriesInDomains(
            NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirPath = [paths objectAtIndex:0];
