Composed tests are not supported

[haines]

Tests may be composed, for example

(deftest addition
  (is (= 4 (+ 2 2)))
  (is (= 7 (+ 3 4))))

(deftest subtraction
  (is (= 1 (- 4 3)))
  (is (= 3 (- 7 4))))

(deftest arithmetic
  (addition)
  (subtraction))

(defn test-ns-hook []
  (arithmetic))

This means that :begin-test-var messages can be nested:

{:type :begin-test-var, :var #'example.test/arithmetic}
{:type :begin-test-var, :var #'example.test/addition}
...
{:type :end-test-var, :var #'example.test/addition}
{:type :begin-test-var, :var #'example.test/subtraction}
...
{:type :end-test-var, :var #'example.test/subtraction}
{:type :end-test-var, :var #'example.test/arithmetic}

This is not supported by test-report.summary/summarize (which assumes that only results appear between :begin- and :end-test-var), and therefore not handled well in the JUnit XML output.

It doesn't appear to be particularly widely used so is probably not a high priority to fix.
