   4 This directory contains files intended to test various aspects of
   5 Emacs's functionality.  Please help add tests!
   6
   7 Emacs uses ERT, Emacs Lisp Regression Testing, for testing.  See (info
   8 "(ert)") or https://www.gnu.org/software/emacs/manual/html_node/ert/
   9 for more information on writing and running tests.
  10
  11 All ERT test files are supposed to run from subdirectory automated/.
  12 The Makefile in that directory supports the following targets:
  13
  14 * make check
  15   Run all tests as defined in the directory.  Expensive tests are
  16   suppressed.  The result of the tests for <filename>.el is stored in
  17   <filename>.log.
  18
  19 * make check-maybe
  20   Like "make check", but run only the tests for files which have
  21   unresolved prerequisites.
  22
  23 * make check-expensive
  24   Like "make check", but run also the tests marked as expensive.
  25
  26 * make <filename>  or  make <filename>.log
  27   Run all tests declared in <filename>.el.  This includes expensive
  28   tests.  In the former case the output is shown on the terminal, in
  29   the latter case the output is written to <filename>.log.
  30
  31 ERT offers selectors, which make it possible to filter out which test
  32 cases shall run.  The make variable $(SELECTOR) gives you a simple
  33 mean to use your own selectors.  The ERT manual describes how
  34 selectors are constructed, see (info "(ert)Test Selectors") or
  35 https://www.gnu.org/software/emacs/manual/html_node/ert/Test-Selectors.html
  36
  37 You could use predefined selectors of the Makefile.  "make <filename>
  38 SELECTOR='$(SELECTOR_DEFAULT)'" runs all tests for <filename>.el
  39 except the tests tagged as expensive.
  40
  41 If your test file contains the tests "test-foo", "test2-foo" and
  42 "test-foo-remote", and you want to run only the former two tests, you
  43 could use a selector regexp: "make <filename> SELECTOR='\"foo$$\"'".
