;;; Commentary:
;; This test suite runs tests that use and depend on MH programs
;; installed on the system.
;; When running such tests, MH-E can use a particular MH variant
;; installed on the system, or it can use the mocks provided here.
;; (Setup is done by the `with-mh-test-env' macro.)
;; By setting environment variable TEST_MH_PATH, you can select which of
;; the installed MH variants to use, or ignore them all and use mocks.
;; See also the script test-all-mh-variants.sh in this directory.
;; 1. To run these tests against the default MH variant installed on
;; this system:
;; cd ../.. && make lisp/mh-e/mh-utils-tests
;; 2. To run these tests against an MH variant installed in a
;; specific directory, set TEST_MH_PATH, as in this example:
;; cd ../.. && make lisp/mh-e/mh-utils-tests TEST_MH_PATH=/usr/local/nmh/bin
;; 3. To search for and run these tests against all MH variants
;; installed on this system:
;; ./test-all-mh-variants.sh
;; Setting the environment variable TEST_MH_DEBUG or the Lisp variable
;; mh-test-utils-debug-mocks logs access to the file system during the test.
