You have (at least) two possibilities:
1. write the test method to call setName(someValue) and then:
assertEquals(expected=someValue,actual=obj.getName());
This tests that the set/get pair work as expected.
2. write a CFC to extend the one under test and add a getVariables()
method then:
obj = createObject("component","extendedCFC");
obj.setName(someValue);
assertEquals(expected=someValue,actual=obj.getVariables().name);
This tests that set actually sets variables.name correctly - but
exposes implementation details.
It's a tradeoff (not surprisingly) since you can test more atomic
things if you use more knowledge of the implementation - which couples
your test code to your implementation more closely (not a good thing
in general).
