The manual states:

   Both ‘ert-run-tests-interactively’ and ‘ert-run-tests-batch’ are
implemented on top of the lower-level test handling code in the sections
of ‘ert.el’ labeled “Facilities for running a single test”, “Test
selectors”, and “Facilities for running a whole set of tests”.

   If you want to write code that works with ERT tests, you should take
a look at this lower-level code.  Symbols that start with ‘ert--’ are
internal to ERT, whereas those that start with ‘ert-’ are meant to be
usable by other code.  But there is no mature API yet.


I don't know what's missing before the API can be considered "mature", but 
adding some documentation about the API to the manual instead of referring to 
the source code would be a good first step.
