I wanted to create for my RestKit mappings simple tests to get all the complicated relation mappings correct. First I tried it with usual tests but soon gave up because they start the whole application which made the tests quite slow and network dependent.
So I remembered the possibility of creating logic tests which require only a small testbed. After some time of unsuccessful attempts I remembered, that using CocoaPods might have an impact on the newly created Target for the logic tests. So I had to set the CocoaPods configuration for the new target in the project configuration.
But still it was not working because the linker had problems in finding my own classes. I checked everything: Imports, target dependencies, associated targets of the class files, header search paths, etc. But nothing seemed to help.
Until I found a little bit strange solution on the net which did the trick:
Setting the “Bundle Loader” and “Test Host” fields in the build settings:
Bundle Loader = $(BUILT_PRODUCTS_DIR)/<identifier>.app/<identifier> Test Host = $(BUNDLE_LOADER)
After this it worked fine. But as far as I understood it the idea of logic tests is not to start the full simulator and application. Maybe someday I will find out.
