Today I am facing the same problem, not sure if this is available only recently - instead of using import TARGET_NAME in the test file and / or declaring your classes / methods as public , you can add your file to your target tests through the XCode File Inspector .
Cmd + Opt + 1 to display it in any file, and check the Target Membership checkbox for your target.

You may need to rebuild .... Cmd + b .
If this is specific to my system .... I am running Xcode 6.3 beta 1 and testing through Quick + Nimble, both installed with the latest beta version of cocoapods.
