6 Test::Strict - Check syntax, presence of use strict; and test coverage
7
9 Version 0.52
10
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 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 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 use Test::Strict;
26 all_perl_files_ok(); # Syntax ok and use strict;
27 or
29 use Test::Strict;
31 all_perl_files_ok( @mydirs );
32 "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 use Test::Strict;
38 all_cover_ok( 80 ); # at least 80% coverage
39 or
41 use Test::Strict;
43 all_cover_ok( 80, 't/' );
44
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 Another good practice this module can test is to "use strict;" in all
50 perl files.
51 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 Along with Test::Pod, this module can provide the first tests to setup
57 for a module author.
58 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.
62
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 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 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 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 List taken from Module::CPANTS::Kwalitee::Uses v95
86 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 List taken from Module::CPANTS::Kwalitee::Uses v95
93 warnings_ok( $file [, $text] )
95 Check if warnings have been turned on.
96 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 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 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 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 If the test plan is defined:
119 use Test::Strict tests => 18;
121 all_perl_files_ok();
122 the total number of files tested must be specified.
124 You can control which tests are run on each perl site through:
126 $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 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 The threshold can be modified through
141 $Test::Strict::COVERAGE_THRESHOLD.
142 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 The path to "cover" utility can be modified through
148 $Test::Strict::COVER.
149 The 50% threshold is a completely arbitrary value, which should not be
151 considered as a good enough coverage.
152 The total coverage is the return value of "all_cover_ok()".
154
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.
