Cram runs +each command and compares the command output in the test with the +command's actual output. + +Here's a snippet from `Cram's own test suite`_:: + + The $PYTHON environment variable should be set when running this test + from Python. + + $ [ -n "$PYTHON" ] || PYTHON="`which python`" + $ [ -n "$PYTHONPATH" ] || PYTHONPATH="$TESTDIR/.." && export PYTHONPATH + $ if [ -n "$COVERAGE" ]; then + > coverage erase + > alias cram="`which coverage` run --branch -a $TESTDIR/../scripts/cram" + > else + > alias cram="$PYTHON $TESTDIR/../scripts/cram" + > fi + $ command -v md5 > /dev/null || alias md5=md5sum + + Usage: + + $ cram -h + [Uu]sage: cram \[OPTIONS\] TESTS\.\.\.

The only special characters supported are + ``*`` and ``?``. Both characters can be escaped using ``\``, and the + backslash can be escaped itself. + +* Output lines ending with either of the above keywords are always + first matched literally with actual command output. + +* Lines ending with a space and the keyword ``(no-eol)`` will match + actual output that doesn't end in a newline. + +* Actual output lines containing unprintable characters are escaped + and suffixed with a space and the keyword ``(esc)``. Lines matching + unprintable output must also contain the keyword. + +* Anything else is a comment. + +.. _Cram's own test suite: https://bitbucket.org/brodie/cram/src/default/tests/cram.t +.. _Perl-compatible regular expressions: https://en.wikipedia.org/wiki/Perl_Compatible_Regular_Expressions + + +Download +-------- + +* `cram-0.7.tar.gz`_ (32 KB, requires Python 2.4-2.7 or Python 3.1 or newer) + +.. _cram-0.7.tar.gz: https://bitheap.org/cram/cram-0.7.tar.gz + + +Installation +------------ + +Install Cram using make:: + + $ wget https://bitheap.org/cram/cram-0.7.tar.gz + $ tar zxvf cram-0.7.tar.gz + $ cd cram-0.7 + $ make install + + +Usage +----- + +Cram will print a dot for each passing test. If a test fails, a +`unified context diff`_ is printed showing the test's expected output +and the actual output. Skipped tests (empty tests and tests that exit +with return code ``80``) are marked with ``s`` instead of a dot. + +For example, if we run Cram on `its own example tests`_:: + + .s.! + --- examples/fail.t + +++ examples/fail.t.err + @@ -3,21 +3,22 @@ + $ echo 1 + 1 + $ echo 1 + - 2 + + 1 + $ echo 1 + 1 + + Invalid regex: + + $ echo 1 + - +++ (re) + + 1 + + Offset regular expression: + + $ printf 'foo\nbar\nbaz\n\n1\nA\n@\n' + foo + + bar + baz + + \d (re) + [A-Z] (re) + - # + + @ + s. + # Ran 6 tests, 2 skipped, 1 failed. + +Cram will also write the test with its actual output to +``examples/fail.t.err``, allowing you to use other diff tools. This +file is automatically removed the next time the test passes. + +When you're first writing a test, you might just write the commands +and run the test to see what happens. If you run Cram with ``-i`` or +``--interactive``, you'll be prompted to merge the actual output back +into the test. This makes it easy to quickly prototype new tests. + +You can specify a default set of options by creating a ``.cramrc`` +file. For example:: + + [cram] + verbose = True + indent = 4 + +Is the same as invoking Cram with ``--verbose`` and ``--indent=4``. + +To change what configuration file Cram loads, you can set the +``CRAMRC`` environment variable. You can also specify command line +options in the ``CRAM`` environment variable. + +Note that the following environment variables are reset before tests +are run: + +* ``TMPDIR``, ``TEMP``, and ``TMP`` are set to the test runner's + ``tmp`` directory. + +* ``LANG``, ``LC_ALL``, and ``LANGUAGE`` are set to ``C``. + +* ``TZ`` is set to ``GMT``. + +* ``COLUMNS`` is set to ``80``. (Note: When using ``--shell=zsh``, + this cannot be reset. It will reflect the actual terminal's width.) + +* ``CDPATH`` and ``GREP_OPTIONS`` are set to an empty string. + +Cram also provides the following environment variables to tests: + +* ``CRAMTMP``, set to the test runner's temporary directory. + +* ``TESTDIR``, set to the directory containing the test file. + +* ``TESTFILE``, set to the basename of the current test file. + +* ``TESTSHELL``, set to the value specified by ``--shell``. + +Also note that care should be taken with commands that close the test +shell's ``stdin``. For example, if you're trying to invoke ``ssh`` in +a test, try adding the ``-n`` option to prevent it from closing +``stdin``. Similarly, if you invoke a daemon process that inherits +``stdout`` and fails to close it, it may cause Cram to hang while +waiting for the test shell's ``stdout`` to be fully closed. + +.. _unified context diff: https://en.wikipedia.org/wiki/Diff#Unified_format +.. _its own example tests: https://bitbucket.org/brodie/cram/src/default/examples/ + + +Development +----------- + +Download the official development repository using Mercurial_:: + + hg clone https://bitbucket.org/brodie/cram + +Or Git_:: + + git clone https://github.com/brodie/cram.git + +Test Cram using Cram:: + + pip install -r requirements.txt + make test + +Visit Bitbucket_ or GitHub_ if you'd like to fork the project, watch +for new changes, or report issues. + +.. _Mercurial: http://mercurial.selenic.com/ +.. _Git: http://git-scm.com/ +.. _coverage.py: http://nedbatchelder.com/code/coverage/ +.. _Bitbucket: https://bitbucket.org/brodie/cram +.. _GitHub: https://github.com/brodie/cram + + |
