Currently I have to create a parameterized test class for every method that I want to test with several different inputs. Is there a way to add this together in one file?

Right now there's `CalculatorTestAdd.java` which has a set of parameters that are used to check if the `Add()` function works properly. Is there a possbility for me to 'connect' this set to the `Add()` function and create an additional set meant for the `Subtract()` method and add this method in the same test class, resulting in one file called `CalculatorTest.java`?
