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