Unit test call controller

I tried to search on the web but I could not find such thing. What I wanna do is the following (This is what my boss asked me):

From the controller I need to call the unit testing at run-time in Dev and Production:

1. I need to know know if the API name has changed or not;
2. If the API number and type of input and output parameters are the same;
3. The format of the data in input/output parameters is as expected;

Is it possible to accomplish? Please, help.
