Junit5 ‐ Testing private functions

Using @OpenForTesting annotation

• We can use the annotation @OpenForTesting on the production code and mark the function public to test
• This is not the recommended way

Testing the public functions enclosed that contain private function

• Here we can just test the public function that contains the private one test the outcome and assume the private function works
• This is a better way of testing the private functions in the business logic
