DESCRIPTION
A testing framework for testing various Lintian files for common
errors.
FUNCTIONS
test_check_desc(OPTS, CHECKS...)
Test check desc files (and the tags in them) for common errors.
OPTS is a HASHREF containing key/value pairs, which are described
below.
CHECKS is a list of paths in which to check desc files. Any given
element in CHECKS can be either a file or a dir. Files are assumed
to be check desc file. Directories are searched and all .desc
files in those dirs are processed.
As the number of tests depends on the number of tags in desc, it is
difficult to "plan ahead" when using this test. It is therefore
recommended to not specify a plan and use done_testing().
This sub uses a Data file (see "load_profile_for_test ([PROFNAME[,
INC...]])").
OPTS may contain the following key/value pairs:
filter
If defined, it is a filter function that examines $_ (or its
first argument) and returns a truth value if $_ should be
considered or false otherwise. $_ will be the path to the
current file (or dir) in question; it may be relative or
absolute.
NB: all elements in CHECKS are subject to the filter.
CAVEAT: If the filter rejects a directory, none of the files in
it will be considered either. Even if the filter accepts a
file, that file will only be processed if it has the proper
extension (i.e. with .desc).
translation
If defined and a truth value, the desc files are expected to
contain translations. Otherwise, they must be regular checks.
test_load_profiles(ROOT, INC...)
Test that all profiles in ROOT/profiles are loadable. INC will be
the INC path used as include path for the profile.
If INC is omitted, then the include path will consist of (ROOT,
'/usr/share/lintian'). Otherwise, INC will be used as is (and
should include ROOT).
This sub will do one test per profile loaded.
test_load_checks(OPTS, DIR[, CHECKNAMES...])
Test that the Perl module implementation of the checks can be
loaded and has a run sub.
OPTS is a HASHREF containing key/value pairs, which are described
below.
DIR is the directory where the checks can be found.
CHECKNAMES is a list of check names. If CHECKNAMES is given, only
the checks in this list will be processed. Otherwise, all the
checks in DIR will be processed.
For planning purposes, every check processed counts for 2 tests and
the call itself does on additional check. So if CHECKNAMES
contains 10 elements, then 21 tests will be done (2 * 10 + 1).
Filtered out checks will not be counted.
All data files created at compile time or in the file scope will be
loaded immediately (instead of lazily as done during the regular
runs). This is done to spot missing data files or typos in their
names. Therefore, this sub will load a profile if one hasn't been
loaded already. (see "load_profile_for_test ([PROFNAME[,
INC...]])")
OPTS may contain the following key/value pairs:
filter
If defined, it is a filter function that examines $_ (or its
first argument) and returns a truth value if $_ should be
considered or false otherwise. $_ will be the path to the
current file (or dir) in question; it may be relative or
absolute.
NB: filter is not used if CHECKNAMES is given.
CAVEAT: If the filter rejects a directory, none of the files in
it will be considered either. Even if the filter accepts a
file, that file will only be processed if it has the proper
extension (i.e. with .desc).
load_profile_for_test ([PROFNAME[, INC...]])
Load a Lintian::Profile and ensure Data files can be used. This is
needed if the test needs to access a data file or if a special
profile is needed for the test. It does not test the profile for
issues.
PROFNAME is the name of the profile to load. It can be omitted, in
which case the sub ensures that a profile has been loaded. If no
profile has been loaded, 'debian/main' will be loaded.
INC is a list of extra "include dirs" (or Lintian "roots") to be
used for finding the profile. If not specified, it defaults to
$ENV{'LINTIAN_BASE'} and /usr/share/lintian (in order). INC is
ignored if a profile has already been loaded.
CAVEAT: Only one profile can be loaded in a given test. Once a
profile has been loaded, it is not possible to replace it with
another one. So if this is invoked multiple times, PROFNAME must
be omitted or must match the name of the loaded profile.
program_name_to_perl_paths(PROGNAME)
Map the program name (e.g. $0) to a list of directories or/and
files that should be processed.
This helper sub is mostly useful for splitting up slow tests run
over all Perl scripts/modules in Lintian. This allows better use
of multiple cores. Example:
t/scripts/my-test/
runner.pl
checks.t -> runner.pl
collection.t -> runner.pl
...
And then in runner.pl:
use Test::Lintian;
my @paths = program_name_to_perl_paths($0);
# test all files/dirs listed in @paths
For a more concrete example, see t/scripts/01-critic/ and the
files/symlinks beneath it.
