Nice question... Basically unit testing is about providing the input (to a class or method or anything) and verifying if it returns the expected result. Since the constructor in your question is 'private' , it cannot be called from outside the class. So no need to test it as per the principles of unit testing. Still if you want to unit test it, then call it inside a public method in the class and unit test this public method

Edit: private constructors are used only in static classes

Yes, you do this by instantiating the object and then asserting the fields of the object are initialized properly. You can also assert that no exception was thrown during the constructor. You can check private fields through reflection if you need to.

In your case it depends on what you want to check in the unit test...
