DESCRIPTION

27       This class provides a way to test configuration models with tests
28       files.  This class was designed to tests several models and run several
29       tests cases per model.
30
31       A specific layout for test files must be followed.
32
33   Sub test specification
34       Each subtest is defined in a file like:
35
36        t/model_tests.d/<app-name>-test-conf.pl
37
38       This file specifies that "app-name" (which is defined in
39       "lib/Config/Model/*.d" directory) is used for the test cases defined in
40       the "*-test-conf.pl" file. The model to test is inferred from the
41       application name to test.
42
43       This file contains a list of test case (explained below) and expects a
44       set of files used as test data. The layout of these test data files is
45       explained in next section.
46
47   Simple test file layout
48       Each test case is represented by a configuration file (not a directory)
49       in the "*-examples" directory. This configuration file is used by the
50       model to test and is copied as "$confdir/$conf_file_name" using the
51       test data structure explained below.
52
53       In the example below, we have 1 app model to test: "lcdproc" and 2
54       tests cases. The app name matches the file specified in
55       "lib/Config/Model/*.d" directory. In this case, the app name matches
56       "lib/Config/Model/system.d/lcdproc"
57
58        t
59        |-- model_test.t
60        \-- model_tests.d           # do not change directory name
61            |-- lcdproc-test-conf.pl   # subtest specification for lcdproc app
62            \-- lcdproc-examples
63                |-- t0              # test case t0
64                \-- LCDD-0.5.5      # test case for older LCDproc
65
66       Subtest specification is written in "lcdproc-test-conf.pl" file (i.e.
67       this module looks for files named like "<app-name>-test-conf.pl>").
68
69       Subtests data is provided in files in directory "lcdproc-examples" (
70       i.e. this modules looks for test data in directory
71       "<model-name>-examples>". "lcdproc-test-conf.pl" contains instructions
72       so that each file is used as a "/etc/LCDd.conf" file during each test
73       case.
74
75       "lcdproc-test-conf.pl" can contain specifications for more test cases.
76       Each test case requires a new file in "lcdproc-examples" directory.
77
78       See "Examples" for a link to the actual LCDproc model tests
79
80   Test file layout for multi-file configuration
81       When a configuration is spread over several files, each test case is
82       provided in a sub-directory. This sub-directory is copied in "conf_dir"
83       (a test parameter as explained below)
84
85       In the example below, the test specification is written in
86       "dpkg-test-conf.pl". Dpkg layout requires several files per test case.
87       "dpkg-test-conf.pl" contains instructions so that each directory under
88       "dpkg-examples" is used.
89
90        t/model_tests.d
91        \-- dpkg-test-conf.pl         # subtest specification
92        \-- dpkg-examples
93            \-- libversion            # example subdir, used as test case name
94                \-- debian            # directory for used by test case
95                    |-- changelog
96                    |-- compat
97                    |-- control
98                    |-- copyright
99                    |-- rules

102                    \-- watch
103
104       See "Examples" for a link to the (many) Dpkg model tests
105
106   More complex file layout
107       Each test case is a sub-directory on the "*-examples" directory and
108       contains several files. The destination of the test files may depend on
109       the system (e.g. the OS). For instance, system wide "ssh_config" is
110       stored in "/etc/ssh" on Linux, and directly in "/etc" on MacOS.
111
112       These files are copied in a test directory using a "setup" parameter in
113       test case specification.
114
115       Let's consider this example of 2 tests cases for ssh:
116
117        t/model_tests.d/
118        |-- ssh-test-conf.pl
119        |-- ssh-examples
120            \-- basic
121                |-- system_ssh_config
122                \-- user_ssh_config
123
124       Unfortunately, "user_ssh_config" is a user file, so you need to specify
125       where is located the home directory of the test with another global
126       parameter:
127
128         home_for_test => '/home/joe' ;
129
130       For Linux only, the "setup" parameter is:
131
132        setup => {
133          system_ssh_config => '/etc/ssh/ssh_config',
134          user_ssh_config   => "~/.ssh/config"
135        }
136
137       On the other hand, system wide config file is different on MacOS and
138       the test file must be copied in the correct location. When the value of
139       the "setup" hash is another hash, the key of this other hash is used as
140       to specify the target location for other OS (as returned by Perl $^O
141       variable:
142
143             setup => {
144               'system_ssh_config' => {
145                   'darwin' => '/etc/ssh_config',
146                   'default' => '/etc/ssh/ssh_config',
147               },
148               'user_ssh_config' => "~/.ssh/config"
149             }
150
151       "systemd" is another beast where configuration files can be symlinks to
152       "/dev/null" or other files. To emulate this situation, use an array as
153       setup target:
154
155         setup => {
156             # test data file => [ link (may be repeated), ..       link(s) target contains test data ]
157             'ssh.service' => [ '/etc/systemd/system/sshd.service', '/lib/systemd/system/ssh.service' ]
158         }
159
160       This will result in a symlink like:
161
162          wr_root/model_tests/test-sshd-service/etc/systemd/system/sshd.service
163          -> /absolute_path_to/wr_root/model_tests/test-sshd-service/lib/systemd/system/ssh.service
164
165       See the actual Ssh and Sshd model tests
166       <https://github.com/dod38fr/config-model-
167       openssh/tree/master/t/model_tests.d>
168
169   Basic test specification
170       Each model subtest is specified in "<app>-test-conf.pl". This file must
171       return a data structure containing the test specifications. Each test
172       data structure contains global parameters (Applied to all tests cases)
173       and test cases parameters (parameters are applied to the test case)
174
175        use strict;
176        use warnings;
177        {
178          # global parameters
179
180          # config file name (used to copy test case into test wr_root/model_tests directory)
181          conf_file_name => "fstab",
182          # config dir where to copy the file (optional)
183          conf_dir => "etc",
184          # home directory for this test
185          home_for_test => '/home/joe'
186
187          tests =>  [
188            {
189              # test case 1
190              name => 'my_first_test',
191              # other test case parameters
192            },
193            {
194              # test case 2
195              name => 'my_second_test',
196              # other test case parameters
197            },
198            # ...
199          ],
200        };
201
202        # do not add 1; at the end of the file
203
204       In the example below, "t0" file is copied in
205       "wr_root/model_tests/test-t0/etc/fstab".
206
207        use strict;
208        use warnings;
209        {
210          # list of tests.
211          tests => [
212            {
213              # test name
214              name => 't0',
215              # add optional specification here for t0 test
216            },
217            {
218              name => 't1',
219              # add optional specification here for t1 test
220            },
221          ]
222        };
223
224       You can suppress warnings by specifying "no_warnings => 1" in each test
225       case. On the other hand, you may also want to check for warnings
226       specified to your model. In this case, you should avoid specifying
227       "no_warnings" here and specify warning tests or warning filters as
228       mentioned below.
229
230       See actual fstab test <https://github.com/dod38fr/config-
231       model/blob/master/t/model_tests.d/fstab-test-conf.pl>.
232
233   Skip a test
234       A test file can be skipped using "skip" global test parameter.
235
236       In this example, test is skipped when not running on a Debian system:
237
238        eval { require AptPkg::Config; };
239        my $skip = ( $@ or not -r '/etc/debian_version' ) ? 1 : 0;
240
241        {
242          skip => $skip,
243          tests => [ ] ,
244        };
245
246   Internal tests or backend tests
247       Some tests require the creation of a configuration class dedicated for
248       test (typically to test corner cases on a backend).
249
250       This test class can be created directly in the test specification by
251       specifying tests classes in "config_classes" global test parameter in
252       an array ref. Each array element is a data structure that use
253       create_config_class parameters.  See for instance the layer test
254       <https://github.com/dod38fr/config-
255       model/blob/master/t/model_tests.d/layer-test-conf.pl> or the test for
256       shellvar backend <https://github.com/dod38fr/config-
257       model/blob/master/t/model_tests.d/backend-shellvar-test-conf.pl>.
258
259       In this case, no application exist for such classes so the model to
260       test must be specified in a global test parameter:
261
262         return {
263           config_classes => [ { name => "Foo", element => ... } , ... ],
264           model_to_test => "Foo",
265           tests => [ ... ]
266         };
267
268   Test specification with arbitrary file names
269       In some models, like "Multistrap", the config file is chosen by the
270       user. In this case, the file name must be specified for each tests
271       case:
272
273        {
274          tests => [ {
275              name        => 'arm',
276              config_file => '/home/foo/my_arm.conf',
277              check       => {},
278           }]
279        };
280
281       See the actual multistrap test <https://github.com/dod38fr/config-
282       model/blob/master/t/model_tests.d/multistrap-test-conf.pl>.
283
284   Backend argument
285       Some application like systemd requires a backend argument specified by
286       user (e.g. a service name for systemd). The parameter "backend_arg" can
287       be specified to emulate this behavior.
288
289   Re-use test data
290       When the input data for test is quite complex (several files), it may
291       be interesting to re-use these data for other test cases. Knowing that
292       test names must be unique, you can re-use test data with "data_from"
293       parameter. For instance:
294
295         tests => [
296           {
297               name  => 'some-test',
298               # ...
299           },
300           {
301               name  => 'some-other-test',
302               data_from  => 'some-test',    # re-use data from test above
303               # ...
304           },
305         ]
306
307       See plainfile backend test <https://github.com/dod38fr/config-
308       model/blob/master/t/model_tests.d/backend-plainfile-test-conf.pl> for a
309       real life example.
310
311       Likewise, it may be useful to re-use test data from another group of
312       test. Lets see this example from "systemd-service-test-conf.pl":
313
314           {
315               name => 'transmission',
316               data_from_group => 'systemd', # i.e from ../systemd-examples
317           }
318
319       "data_from" and "data_from_group" can be together.
320
321   Test scenario
322       Each subtest follow a sequence explained below. Each step of this
323       sequence may be altered by adding test case parameters in
324       "<model-to-test>-test-conf.pl":
325
326       •   Setup test in "wr_root/model_tests/<subtest name>/". If your
327           configuration file layout depend on the target system, you will
328           have to specify the path using "setup" parameter.  See "More
329           complex file layout".
330
331       •   Create configuration instance, load config data and check its
332           validity. Use "load_check => 'no'" if your file is not valid.
333
334       •   Check for config data warnings. You should pass the list of
335           expected warnings that are emitted through Log::Log4perl. The array
336           ref is passed as is to the "expect" function of "expect" in
337           Test::Log::Lo4Perl. E.g:
338
339               log4perl_load_warnings => [
340                    [ 'Tree.Node', (warn => qr/deprecated/) x 2 ]  ,
341                    [ 'Tree.Element.Value' , ( warn => qr/skipping/) x 2 ]
342               ]
343
344           The Log classes are specified in "cme/Logging".
345
346           Log levels below "warn" are ignored.
347
348           Note that log tests are disabled when "--log" option is used, hence
349           all warnings triggered by the tests are shown.
350
351           Config::Model is currently transitioning from traditional "warn" to
352           warn logs. To avoid breaking all tests based on this module, the
353           warnings are emitted through Log::Log4perl only when
354           $::_use_log4perl_to_warn is set. This hack will be removed once all
355           warnings checks in tests are ported to log4perl checks.
356
357       •   DEPRECATED. Check for config data warning. You should pass the list
358           of expected warnings.  E.g.
359
360               load_warnings => [ qr/Missing/, (qr/deprecated/) x 3 , ],
361
362           Use an empty array_ref to mask load warnings.
363
364       •   Optionally run update command:
365
366            update => {
367               returns => 'foo' , # optional
368               no_warnings => [ 0 | 1 ], # default 0
369               quiet => [ 0 | 1], # default 0, passed to update method
370               load4perl_update_warnings => [ ... ] # Test::Log::Log4perl::expect arguments
371            }
372
373           Where:
374
375           •   "returns" is the expected return value (optional).
376
377           •   "no_warnings" can be used to suppress the warnings coming from
378               Config::Model::Value. Note that "no_warnings => 1" may be
379               useful for less verbose test.
380
381           •   "quiet" to suppress progress messages during update.
382
383           •   "log4perl_update_warnings" is used to check the warnings
384               produced during update. The argument is passed to "expect"
385               function of Test::Log::Log4perl. See "load_warnings" parameter
386               above for more details.
387
388           •   DEPRECATED. "update_warnings" is an array ref of quoted regexp
389               (See qr operator) to check the warnings produced during update.
390               Please use "log4perl_update_warnings" instead.
391
392           All other arguments are passed to "update" method.
393
394       •   Optionally load configuration data. You should design this config
395           data to suppress any error or warning mentioned above. E.g:
396
397               load => 'binary:seaview Synopsis="multiplatform interface for sequence alignment"',
398
399           See Config::Model::Loader for the syntax of the string accepted by
400           "load" parameter.

402       •   Optionally, run a check before running apply_fix (if any). This
403           step is useful to check warning messages:
404
405              check_before_fix => {
406                 dump_errors   => [ ... ] # optional, see below
407                 log4perl_dump_warnings => [ ... ] # optional, see below
408              }
409
410           Use "dump_errors" if you expect issues:
411
412             check_before_fix => {
413               dump_errors =>  [
414                   # the issues  and a way to fix the issue using Config::Model::Node::load
415                   qr/mandatory/ => 'Files:"*" Copyright:0="(c) foobar"',
416                   qr/mandatory/ => ' License:FOO text="foo bar" ! Files:"*" License short_name="FOO" '
417               ],
418             }
419
420           Likewise, specify any expected warnings:
421
422             check_before_fix => {
423                   log4perl_dump_warnings => [ ... ],
424             }
425
426           "log4perl_dump_warnings" passes the array ref content to "expect"
427           function of Test::Log::Log4perl.
428
429           Both "log4perl_dump_warnings" and "dump_errors" can be specified in
430           "check_before_fix" hash.
431
432       •   Optionally, call apply_fixes:
433
434               apply_fix => 1,
435
436       •   Call dump_tree to check the validity of the data after optional
437           "apply_fix". This step is not optional.
438
439           As with "check_before_fix", both "dump_errors" or
440           "log4perl_dump_warnings" can be specified in "full_dump" parameter:
441
442            full_dump => {
443                log4perl_dump_warnings => [ ... ], # optional
444                dump_errors            => [ ... ], # optional
445            }
446
447       •   Run specific content check to verify that configuration data was
448           retrieved correctly:
449
450               check => {
451                   'fs:/proc fs_spec' => "proc",
452                   'fs:/proc fs_file' => "/proc",
453                   'fs:/home fs_file' => "/home",
454               },
455
456           The keys of the hash points to the value to be checked using the
457           syntax described in "grab" in Config::Model::Role::Grab.
458
459           Multiple check on the same item can be applied with a array ref:
460
461               check => [
462                   Synopsis => 'fix undefined path_max for st_size zero',
463                   Description => [ qr/^The downstream/,  qr/yada yada/ ]
464               ]
465
466           You can run check using different check modes (See "fetch" in
467           Config::Model::Value) by passing a hash ref instead of a scalar :
468
469               check  => {
470                   'sections:debian packages:0' => { mode => 'layered', value => 'dpkg-dev' },
471                   'sections:base packages:0'   => { mode => 'layered', value => "gcc-4.2-base' },
472               },
473
474           The whole hash content (except "value") is passed to  grab and
475           fetch
476
477           A regexp can also be used to check value:
478
479              check => {
480                 "License text" => qr/gnu/i,
481              }
482
483           And specification can nest hash or array style:
484
485              check => {
486                 "License:0 text" => qr/gnu/i,
487                 "License:1 text" => [ qr/gnu/i, qr/Stallman/ ],
488                 "License:2 text" => { mode => 'custom', value => [ qr/gnu/i , qr/Stallman/ ] },
489                 "License:3 text" => [ qr/General/], { mode => 'custom', value => [ qr/gnu/i , qr/Stallman/ ] },
490              }
491
492       •   Verify if a hash contains one or more keys (or keys matching a
493           regexp):
494
495            has_key => [
496               'sections' => 'debian', # sections must point to a hash element
497               'control' => [qw/source binary/],
498               'copyright Files' => qr/.c$/,
499               'copyright Files' => [qr/\.h$/], qr/\.c$/],
500            ],
501
502       •   Verify that a hash does not have a key (or a key matching a
503           regexp):
504
505            has_not_key => [
506               'copyright Files' => qr/.virus$/ # silly, isn't ?
507            ],
508
509       •   Verify annotation extracted from the configuration file comments:
510
511               verify_annotation => {
512                       'source Build-Depends' => "do NOT add libgtk2-perl to build-deps (see bug #554704)",
513                       'source Maintainer' => "what a fine\nteam this one is",
514                   },
515
516       •   Write back the config data in "wr_root/model_tests/<subtest
517           name>/".  Note that write back is forced, so the tested
518           configuration files are written back even if the configuration
519           values were not changed during the test.
520
521           You can skip warning when writing back with the global :
522
523               no_warnings => 1,
524
525       •   Check the content of the written files(s) with
526           Test::File::Contents. Tests can be grouped in an array ref:
527
528              file_contents => {
529                       "/home/foo/my_arm.conf" => "really big string" ,
530                       "/home/bar/my_arm.conf" => [ "really big string" , "another"], ,
531                   }
532
533              file_contents_like => {
534                       "/home/foo/my_arm.conf" => [ qr/should be there/, qr/as well/ ] ,
535              }
536
537              file_contents_unlike => {
538                       "/home/foo/my_arm.conf" => qr/should NOT be there/ ,
539              }
540
541       •   Check the mode of the written files:
542
543             file_mode => {
544                "~/.ssh/ssh_config"     => oct(600), # better than 0600
545                "debian/stuff.postinst" => oct(755),
546             }
547
548           Only the last four octets of the mode are tested. I.e. the test is
549           done with " $file_mode & oct(7777) "
550
551           Note: this test is skipped on Windows
552
553       •   Check added or removed configuration files. If you expect changes,
554           specify a subref to alter the file list:
555
556               file_check_sub => sub {
557                   my $list_ref = shift ;
558                   # file added during tests
559                   push @$list_ref, "/debian/source/format" ;
560               },
561
562           Note that actual and expected file lists are sorted before check,
563           adding a file can be done with "push".
564
565       •   Copy all config data from "wr_root/model_tests/<subtest name>/" to
566           "wr_root/model_tests/<subtest name>-w/". This steps is necessary to
567           check that configuration written back has the same content as the
568           original configuration.
569
570       •   Create a second configuration instance to read the conf file that
571           was just copied (configuration data is checked.)
572
573       •   You can skip the load check if the written file still contain
574           errors (e.g.  some errors were ignored and cannot be fixed) with
575           "load_check2 => 'no'"
576
577       •   Optionally load configuration data in the second instance. You
578           should design this config data to suppress any error or warning
579           that occur in the step below. E.g:
580
581               load2 => 'binary:seaview',
582
583           See Config::Model::Loader for the syntax of the string accepted by
584           "load2" parameter.
585
586       •   Compare data read from original data.
587
588       •   Run specific content check on the written config file to verify
589           that configuration data was written and retrieved correctly:
590
591               wr_check => {
592                   'fs:/proc fs_spec' =>          "proc" ,
593                   'fs:/proc fs_file' =>          "/proc",
594                   'fs:/home fs_file' =>          "/home",
595               },
596
597           Like the "check" item explained above, you can run "wr_check" using
598           different check modes.
599
600   Running the test
601       Run all tests with one of these commands:
602
603        prove -l t/model_test.t :: [ --trace ] [ --log ] [ --error ] [ <model_name> [ <regexp> ]]
604        perl -Ilib t/model_test.t  [ --trace ] [ --log ] [ --error ] [ <model_name> [ <regexp> ]]
605
606       By default, all tests are run on all models.
607
608       You can pass arguments to "t/model_test.t":
609
610       •   Optional parameters: "--trace" to get test traces. "--error" to get
611           stack trace in case of errors, "--log" to have logs. E.g.
612
613             # run with log and error traces
614             prove -lv t/model_test.t :: --error --logl
615
616       •   The model name to tests. E.g.:
617
618             # run only fstab tests
619             prove -lv t/model_test.t :: fstab
620
621       •   A regexp to filter subtest E.g.:
622
623             # run only fstab tests foobar subtest
624             prove -lv t/model_test.t :: fstab foobar
625
626             # run only fstab tests foo subtest
627             prove -lv t/model_test.t :: fstab '^foo$'
