Pretty much; nothing too difficult.

In this style of unit test, you have setup() and shutdown() methods that
create and destroy the test objects afresh for each test case, so cases
aren't big long skeins of assertions that will all break given a single
failure.  Instead they're more like 1) call a method that changes an
object's state, 2) call accessors or get attributes to check invariants are
what you expect.  It can be useful to know that .get_parameter_value()
raises an exception while .get_parameter_type() doesn't, or whatever.
