NAME

6       Test::Strict - Check syntax, presence of use strict; and test coverage
7

VERSION

SYNOPSIS

12       "Test::Strict" lets you check the syntax, presence of "use strict;" and
13       presence "use warnings;" in your perl code.  It report its results in
14       standard Test::Simple fashion:
15
16           use Test::Strict tests => 3;
17           syntax_ok( 'bin/myscript.pl' );
18           strict_ok( 'My::Module', "use strict; in My::Module" );
19           warnings_ok( 'lib/My/Module.pm' );
20
21       Module authors can include the following in a t/strict.t and have
22       "Test::Strict" automatically find and check all perl files in a module
23       distribution:
24
25         use Test::Strict;
26         all_perl_files_ok(); # Syntax ok and use strict;
27
28       or
29
30           use Test::Strict;
31           all_perl_files_ok( @mydirs );
32
33       "Test::Strict" can also enforce a minimum test coverage the test suite
34       should reach.  Module authors can include the following in a t/cover.t
35       and have "Test::Strict" automatically check the test coverage:
36
37           use Test::Strict;
38           all_cover_ok( 80 );  # at least 80% coverage
39
40       or
41
42           use Test::Strict;
43           all_cover_ok( 80, 't/' );
44

DESCRIPTION

46       The most basic test one can write is "does it compile ?".  This module
47       tests if the code compiles and play nice with Test::Simple modules.
48
49       Another good practice this module can test is to "use strict;" in all
50       perl files.
51
52       By setting a minimum test coverage through "all_cover_ok()", a code
53       author can ensure his code is tested above a preset level of kwality
54       throughout the development cycle.
55
56       Along with Test::Pod, this module can provide the first tests to setup
57       for a module author.
58
59       This module should be able to run under the -T flag for perl >= 5.6.
60       All paths are untainted with the following pattern:
61       "qr|^([-+@\w./:\\]+)$|" controlled by $Test::Strict::UNTAINT_PATTERN.

FUNCTIONS

64   syntax_ok( $file [, $text] )
65       Run a syntax check on $file by running "perl -c $file" with an external
66       perl interpreter.  The external perl interpreter path is stored in
67       $Test::Strict::PERL which can be modified.  You may prefer "use_ok()"
68       from Test::More to syntax test a module.  For a module, the path
69       (lib/My/Module.pm) or the name (My::Module) can be both used.
70
71   strict_ok( $file [, $text] )
72       Check if $file contains a "use strict;" statement.  "use Moose" and
73       "use Mouse" are also considered valid.  use Modern::Perl is also
74       accepted.
75
76       This is a pretty naive test which may be fooled in some edge cases.
77       For a module, the path (lib/My/Module.pm) or the name (My::Module) can
78       be both used.
79
80   modules_enabling_strict
81       Experimental. Returning a list of modules and pragmata that enable
82       strict.  To modify this list, change
83       @Test::Strict::MODULES_ENABLING_STRICT.
84
85       List taken from Module::CPANTS::Kwalitee::Uses v95
86
87   modules_enabling_warnings
88       Experimental. Returning a list of modules and pragmata that enable
89       warnings To modify this list, change
90       @Test::Strict::MODULES_ENABLING_WARNINGS.
91
92       List taken from Module::CPANTS::Kwalitee::Uses v95
93
94   warnings_ok( $file [, $text] )
95       Check if warnings have been turned on.
96
97       If $file is a module, check if it contains a "use warnings;" or "use
98       warnings::..."  or "use Moose" or "use Mouse" statement. use
99       Modern::Perl is also accepted.  If the perl version is <= 5.6, this
100       test is skipped ("use warnings" appeared in perl 5.6).
101
102       If $file is a script, check if it starts with "#!...perl -w".  If the
103       -w is not found and perl is >= 5.6, check for a "use warnings;" or "use
104       warnings::..."  or "use Moose" or "use Mouse" statement. use
105       Modern::Perl is also accepted.
106
107       This is a pretty naive test which may be fooled in some edge cases.
108       For a module, the path (lib/My/Module.pm) or the name (My::Module) can
109       be both used.
110
111   all_perl_files_ok( [ @directories ] )
112       Applies "strict_ok()" and "syntax_ok()" to all perl files found in
113       @directories (and sub directories).  If no <@directories> is given, the
114       starting point is one level above the current running script, that
115       should cover all the files of a typical CPAN distribution.  A perl file
116       is *.pl or *.pm or *.t or a file starting with "#!...perl"
117
118       If the test plan is defined:
119
120         use Test::Strict tests => 18;
121         all_perl_files_ok();
122
123       the total number of files tested must be specified.
124
125       You can control which tests are run on each perl site through:
126
127         $Test::Strict::TEST_SYNTAX   (default = 1)
128         $Test::Strict::TEST_STRICT   (default = 1)
129         $Test::Strict::TEST_WARNINGS (default = 0)
130         $Test::Strict::TEST_SKIP     (default = []) "Trusted" files to skip
131
132   all_cover_ok( [coverage_threshold [, @t_dirs]] )
133       This will run all the tests in @t_dirs (or current script's directory
134       if @t_dirs is undef) under Devel::Cover and calculate the global test
135       coverage of the code loaded by the tests.  If the test coverage is
136       greater or equal than "coverage_threshold", it is a pass, otherwise
137       it's a fail. The default coverage threshold is 50 (meaning 50% of the
138       code loaded has been covered by test).
139
140       The threshold can be modified through
141       $Test::Strict::COVERAGE_THRESHOLD.
142
143       You may want to select which files are selected for code coverage
144       through $Test::Strict::DEVEL_COVER_OPTIONS, see Devel::Cover for the
145       list of available options.  The default is '+ignore,"/Test/Strict\b"'.
146
147       The path to "cover" utility can be modified through
148       $Test::Strict::COVER.
149
150       The 50% threshold is a completely arbitrary value, which should not be
151       considered as a good enough coverage.
152
153       The total coverage is the return value of "all_cover_ok()".
154

CAVEATS

156       For "all_cover_ok()" to work properly, it is strongly advised to
157       install the most recent version of Devel::Cover and use perl 5.8.1 or
158       above.  In the case of a "make test" scenario, "all_perl_files_ok()"
159       re-run all the tests in a separate perl interpreter, this may lead to
160       some side effects.
