TODO

* FIXME: cut-stream-reader's reader should stop on EOF.
* random value generator.
* cut_generate_uuid.
* rename cut_process_* to cut_child_cutter_*.

  e.g. cutter --filter-by-attribute 'target_version <= 1.0.0'.
* report errors in data setup function.
* add CUTTER_DEBUG technique in test/run-test.sh to tutorial
  as a debugging technique.
* use real data instead of dummy data (e.g. a, b, c, ...)
  for demo screenshot. (It's more realistic)
* add 'what merit we will get' instead of 'what features we
  will get' to introduction document.
* add 'how to become a test junkie from a test amateur' to document.

* elapsed time assert. (compare with past elapsed time?)
* test history chart.
  * N tests

* failmalloc like memory test.
* update option descriptions in README.
* introduce easy sub process debugging mechanism.
* GTK+ UI supports test iterator.
* cut_get_test_name().
* cut_{get,set}_current_test_context() ->
  cut_{get,set}_test_context()
