How to add unit tests for the native iOS module ?

[Amine078]

Hello,
I am trying to add unit tests to the native iOS module which is under development pods. My goal is not to test the module in the example app but in the module itself.
I tried to add a test_spec in the module’s podespec file like mentioned in this link, but that didn’t work.
Do you have an idea or any recommendation on how to add unit tests for the iOS module?
