Yes. A fixture is a function that takes another function as its
argument. It can alter the environment in which tests are run. Like
this:
(defn my-fixture [f]
(...setup, bindings, whatever...
(f)
... teardown, whatever...))
The "use-fixtures" function configures fixtures to run once per test
or once per namespace.

You could do this, but you still can't control the order in which
tests are run. If things need to happen in a particular order, you
either need to use nested tests functions or one large function.
