Answer 1

I don't think you really want to conditionally execute something at runtime based if you are running unit tests or not. That would be a terrible idea IMHO.

What you probably want in your unit tests is to create a mock object of your api class and then inject the mocked version into the class you are testing.

Answer 2

Does your operating system has environmental values? In React, I solve this with checking process.env.NODE_ENV !='test'

Answer 3

You can set an on-launch argument like isTest to YES in your scheme properties (section Test).

And, in your function use this :

BOOL isTest = [[NSUserDefaults standardUserDefaults] boolForKey:@"isTest"];
