Type 'exit' to exit it, it will be cleaned up after you. ... $ gpg -k Alfa gpg: NOTE: THIS IS A DEVELOPMENT VERSION! gpg: It is only intended for test purposes and should NOT be gpg: used in a production environment or with production keys! gpg: /tmp/gpgscm-20170809T144032-run-tests-PFfybw/trustdb.gpg: trustdb created pub dsa1024 1999-03-08 [SCA] A0FF4590BB6122EDEF6E3C542D727CC768697734 uid [ unknown] Alfa Test (demo key) uid [ unknown] Alpha Test (demo key) uid [ unknown] Alice (demo key) sub elg1024 1999-03-08 [E] PATH is adjusted so that you will use the tools from the build tree. Note that the directory is removed when you exit the shell. ** Passing options to the test driver You can set TESTFLAGS to pass flags to 'run-tests.scm'. For example, to speed up the test suite when bisecting, do obj $ make -C tests/openpgp check TESTFLAGS=--parallel See below for the arguments supported by the driver. ** Calling the test driver directly This is a bit tricky because one needs to manually set some environment variables. We should make that easier. See discussion below. From your build directory, do: obj $ srcdir=/tests/openpgp \ GPGSCM_PATH=/tests/gpgscm:/tests/openpgp \ $(pwd)/tests/gpgscm/gpgscm [gpgscm args] \ run-tests.scm [test suite runner args] *** Arguments supported by the test suite runner The test suite runner supports two modes of operation, '--sequential' and '--parallel'. By default the tests are run in sequential order, each one in a clean environment. You can specify the tests to run as positional arguments relative to srcdir (e.g. just 'version.scm'). Note that you do not have to specify setup.scm and finish.scm, they are executed implicitly. The test suite runner can be executed in any location that the current user can write to. It will create temporary files and directories, but will in general clean up all of them. *** Discussion of the various environment variables **** srcdir Must be set to the source of the openpgp test suite. Used to locate data files. **** GPGSCM_PATH Used to locate the Scheme library as well as code used by the test suite. **** GNUPG_BUILD_ROOT This envvar gives the root directory of the build tree. See tests/gpgconf.ctl.in for the way we tell the GnuPG components this location. Note that we can't use that envvar directly because this would allow user scripts and other software to accidently mess up the used components. **** argv[0] run-tests.scm depends on being able to re-exec gpgscm. It uses argv[0] for that. Therefore you must use an absolute path to invoke gpgscm. * How to write tests gpgscm provides a number of functions to aid you in writing tests, as well as bindings to process management abstractions provided by GnuPG. For the Scheme environment provided by TinySCHEME, see the TinySCHEME manual that is included in tests/gpgscm/Manual.txt. For a quick start, please have a look at various tests that are already implemented, e.g. 'encrypt.scm'. ** The test framework The functions info, error, and skip display their first argument and flush the output buffers. error and skip will also terminate the process, signaling that the test failed or should be skipped. (for-each-p msg proc list) will display msg, and call proc with each element of list while displaying the progress appropriately. for-each-p' is similar, but accepts another callback before the 'list' argument to format each item. for-each-p can be safely nested, and the inner progress indicator will be abbreviated using '.'. ** Debugging tests Say you are working on a new test called 'your-test.scm', you can run it on its own using obj $ make -C tests/openpgp check TESTS=your-test.scm but something isn't working as expected. There are several little gadgets that might help. The first one is 'trace', a function that prints the value given to it and evaluates to it. E.g. (trace (+ 2 3)) prints '5' and evaluates to 5. Also, there is an 'assert' macro that aborts the execution if its argument does not evaluate to a trueish value. Feel free to express invariants with it. You can also get an interactive repl by dropping (interactive-repl (current-environment)) anywhere you like. Or, if you want to examine the environment from an operating system shell, use (interactive-shell) ** Interfacing with gpg defs.scm defines several convenience functions. Say you want to parse the colon output from gpg, there is gpg-with-colons that splits the result at newlines and colons, so you can use the result like this: (define (fpr some-key) (list-ref (assoc "fpr" (gpg-with-colons `(--with-fingerprint --list-secret-keys ,some-key))) 9)) Or if you want to count all non-revoked uids for a given key, do (define (count-uids-of-secret-key some-key) (length (filter (lambda (x) (and (string=? "uid" (car x)) (string=? "u" (cadr x)))) (gpg-with-colons `(--with-fingerprint --list-secret-keys ,some-key))))) ** Temporary files (lettmp ) will create and delete temporary files that you can use in . (with-temporary-working-directory ) will create a temporary director, change to that, and clean it up after executing ). make-temporary-file will create a temporary file. You can optionally provide an argument to that function that will serve as tag so you can distinguish the files for debugging. remove-temporary-file will delete a file created using make-temporary-file. ** Monadic transformer and pipe support Tests often perform sequential transformations on files, or connect processes using pipes. To aid you in this, the test framework provides two monadic data structures. (Currently, the implementation mashes the 'bind' operation together with the application of the monad. Also, there is no 'return' operation. I guess all of that could be implemented on top of call/cc, but it isn't at the moment.) *** pipe The pipe monad constructs pipe lines. It consists of a function pipe:do that binds the functions together and manages the execution of the child processes, a family of functions that act as sources, a function to spawn processes, and a family of functions acting as sinks. Sources are pipe:open, pipe:defer, pipe:echo. To spawn a process use pipe:spawn, or the convenience function pipe:gpg. To sink the data use pipe:splice, or pipe:write-to. Example: (pipe:do (pipe:echo "3\n1\n2\n") (pipe:spawn '("/usr/bin/sort")) (pipe:write-to "sorted" (logior O_WRONLY O_CREAT) #o600)) Caveats: Due to the single-threaded nature of gpgscm you cannot use both a source and sink that is implemented in Scheme. pipe:defer and pipe:echo are executing in gpgscm, and so does pipe:splice. *** tr The transformer monad describes sequential file transformations. There is one source function, tr:open. To describe a transformation using some process, use tr:spawn, tr:gpg, or tr:pipe-do. There are several sinks, although sink is not quite the right term, because the data is not consumed, and hence one can use them at any position. The -"sinks" are tr:write-to, tr:call-with-content, tr:assert-identity, and -tr:assert-weak-identity. +"sinks" are tr:write-to, tr:call-with-content, tr:assert-identity, +tr:assert-weak-identity, and tr:assert-same. A somewhat contrived example demonstrating many functions is: (tr:do (tr:pipe-do (pipe:echo "3\n1\n2\n") (pipe:spawn '("/usr/bin/sort"))) (tr:write-to "reference") (tr:call-with-content (lambda (c) (echo "currently, c contains" (string-length c) "bytes"))) (tr:spawn "" '("/usr/bin/gcc" -x c "-E" -o **out** **in**)) (tr:pipe-do (pipe:spawn '("/bin/grep" -v "#"))) (tr:assert-identity "reference")) Caveats: As a convenience, gpgscm allows one to specify command line arguments as Scheme symbols. Scheme symbols, however, are case-insensitive, and get converted to lower case. Therefore, the -E argument must be given as a string in the example above. Similarly, you need to quote numerical values. ** Process management If you just need to execute a single command, there is (call-with-fds cmdline infd outfd errfd) which executes cmdline with the given file descriptors bound to it, and waits for its completion returning the status code. There is (call cmdline) which is similar, but calls the command with a closed stdin, connecting stdout and stderr to stderr if gpgscm is executed with --verbose. (call-check cmdline) raises an exception if the command does not return 0. (call-popen cmdline input) calls a command, writes input to its stdin, and returns any output from stdout, or raises an exception containing stderr on failure. * Sample messages diff --git a/tests/openpgp/shell.scm b/tests/openpgp/shell.scm index 347b3a08c..af4f25498 100644 --- a/tests/openpgp/shell.scm +++ b/tests/openpgp/shell.scm @@ -1,53 +1,55 @@ #!/usr/bin/env gpgscm ;; Copyright (C) 2016 g10 Code GmbH ;; ;; This file is part of GnuPG. ;; ;; GnuPG is free software; you can redistribute it and/or modify ;; it under the terms of the GNU General Public License as published by ;; the Free Software Foundation; either version 3 of the License, or ;; (at your option) any later version. ;; ;; GnuPG is distributed in the hope that it will be useful, ;; but WITHOUT ANY WARRANTY; without even the implied warranty of ;; MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
