clojure.test really doesn't do much. deftests are just
functions, so they can run any arbitrary code you want.
The implementation of `clojure.test/testing` is just
`(binding [*testing-contexts* (conj *testing-contexts* ~string)]
~@body))
You can trivially rebind *testing-contexts* in your code.
The `is` macro is just a fancy version of `assert` that
calls `do-report` with the result.
(if result#
(do-report {:type :pass, :message ~msg, :expected '~form, :actual
...})
(do-report {:type :fail, :message ~msg, :expected '~form, :actual
...}))
So you can generate your own test expressions at runtime.
