How to unit test private object variables mocha chai for typescript project?

After researching this I found the best response would be to test the private variables of an object against the prototype of the object. Effectively then inside the test creating a prototype and accessing the variables in that way. When I do this, however, it seems that all variables are not null but are undefined. How am I able to test the private variables, so that they remain defined?
