This directory contains files intended to test various aspects of
|
||
Emacs's functionality. Please help add tests!
|
||
|
||
See the file file-organization.org for the details of the directory
|
||
structure and file-naming conventions.
|
||
|
||
Emacs uses ERT, Emacs Lisp Regression Testing, for testing. See (info
|
||
"(ert)") or https://www.gnu.org/software/emacs/manual/html_node/ert/
|
||
for more information on writing and running tests.
|
||
|
||
Tests could be tagged by the developer. In this test directory, the
|
||
following tags are recognized:
|
||
|
||
* :expensive-test
|
||
The test needs a serious amount of time to run. It is not intended
|
||
to run on a regular basis by users. Instead, it runs on demand
|
||
only, or during regression tests.
|
||
|
||
* :unstable
|
||
The test is under development. It shall run on demand only.
|
||
|
||
The Makefile in this directory supports the following targets:
|
||
|
||
* make check
|
||
Run all tests as defined in the directory. Expensive and unstable
|
||
tests are suppressed. The result of the tests for <filename>.el is
|
||
stored in <filename>.log.
|
||
|
||
* make check-maybe
|
||
Like "make check", but run only the tests for files which have
|
||
unresolved prerequisites.
|
||
|
||
* make check-expensive
|
||
Like "make check", but run also the tests marked as expensive.
|
||
|
||
* make check-all
|
||
Like "make check", but run all tests.
|
||
|
||
* make <filename> -or- make <filename>.log
|
||
Run all tests declared in <filename>.el. This includes expensive
|
||
tests. In the former case the output is shown on the terminal, in
|
||
the latter case the output is written to <filename>.log.
|
||
|
||
<filename> could be either a relative file name like
|
||
"lisp/files-tests", or a package name like "files-tests".
|
||
|
||
ERT offers selectors, which make it possible to filter out which test
|
||
cases shall run. The make variable $(SELECTOR) gives you a simple
|
||
mean to use your own selectors. The ERT manual describes how
|
||
selectors are constructed, see (info "(ert)Test Selectors") or
|
||
https://www.gnu.org/software/emacs/manual/html_node/ert/Test-Selectors.html
|
||
|
||
You could use predefined selectors of the Makefile. "make <filename>
|
||
SELECTOR='$(SELECTOR_DEFAULT)'" runs all tests for <filename>.el
|
||
except the tests tagged as expensive or unstable.
|
||
|
||
If your test file contains the tests "test-foo", "test2-foo" and
|
||
"test-foo-remote", and you want to run only the former two tests, you
|
||
could use a selector regexp (note that the "$" needs to be doubled to
|
||
protect against "make" variable expansion):
|
||
|
||
make <filename> SELECTOR='"foo$$"'
|
||
|
||
In case you want to use the symbol name of a test as selector, you can
|
||
use it directly:
|
||
|
||
make <filename> SELECTOR='test-foo-remote'
|
||
|
||
Note that although the test files are always compiled (unless they set
|
||
no-byte-compile), the source files will be run when expensive or
|
||
unstable tests are involved, to give nicer backtraces. To run the
|
||
compiled version of a test use
|
||
|
||
make TEST_LOAD_EL=no ...
|
||
|
||
Some tests might take long time to run. In order to summarize the
|
||
<nn> tests with the longest duration, call
|
||
|
||
make SUMMARIZE_TESTS=<nn> ...
|
||
|
||
The tests are run in batch mode by default; sometimes it's useful to
|
||
get precisely the same environment but run in interactive mode for
|
||
debugging. To do that, use
|
||
|
||
make TEST_INTERACTIVE=yes ...
|
||
|
||
Some of the tests require a remote temporary directory
|
||
(autorevert-tests.el, filenotify-tests.el, shadowfile-tests.el and
|
||
tramp-tests.el). Per default, a mock-up connection method is used
|
||
(this might not be possible when running on MS Windows). If you want
|
||
to test a real remote connection, set $REMOTE_TEMPORARY_FILE_DIRECTORY
|
||
to a suitable value in order to overwrite the default value:
|
||
|
||
env REMOTE_TEMPORARY_FILE_DIRECTORY=/ssh:host:/tmp make ...
|
||
|
||
|
||
There are also continuous integration tests on
|
||
<https://hydra.nixos.org/jobset/gnu/emacs-trunk> (see
|
||
admin/notes/hydra) and <https://emba.gnu.org/emacs/emacs> (see
|
||
admin/notes/emba). Both environments provide an environment variable,
|
||
which could be used to determine, whether the tests run in one of
|
||
these test environments.
|
||
|
||
$EMACS_HYDRA_CI indicates the hydra environment, and $EMACS_EMBA_CI
|
||
indicates the emba environment, respectively.
|
||
|
||
|
||
(Also, see etc/compilation.txt for compilation mode font lock tests.)
