.SH "NAME"
Test::Strict \- Check syntax, presence of use strict; and test coverage
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\f(CW\*(C`Test::Strict\*(C'\fR lets you check the syntax, presence of \f(CW\*(C`use strict;\*(C'\fR
and presence \f(CW\*(C`use warnings;\*(C'\fR
in your perl code.
It report its results in standard \f(CW\*(C`Test::Simple\*(C'\fR fashion:
.PP
.Vb 4
\&  use Test::Strict tests => 3;
\&  syntax_ok( \*(Aqbin/myscript.pl\*(Aq );
\&  strict_ok( \*(AqMy::Module\*(Aq, "use strict; in My::Module" );
\&  warnings_ok( \*(Aqlib/My/Module.pm\*(Aq );
.Ve
.PP
Module authors can include the following in a t/strict.t
and have \f(CW\*(C`Test::Strict\*(C'\fR automatically find and check
all perl files in a module distribution:
.PP
.Vb 2
\&  use Test::Strict;
\&  all_perl_files_ok(); # Syntax ok and use strict;
.Ve
.PP
or
.PP
.Vb 2
\&  use Test::Strict;
\&  all_perl_files_ok( @mydirs );
.Ve
.PP
\&\f(CW\*(C`Test::Strict\*(C'\fR can also enforce a minimum test coverage
the test suite should reach.
Module authors can include the following in a t/cover.t
and have \f(CW\*(C`Test::Strict\*(C'\fR automatically check the test coverage:
.PP
.Vb 2
\&  use Test::Strict;
\&  all_cover_ok( 80 );  # at least 80% coverage
.Ve
.PP
or
.PP
.Vb 2
\&  use Test::Strict;
\&  all_cover_ok( 80, \*(Aqt/\*(Aq );
.Ve
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The most basic test one can write is \*(L"does it compile ?\*(R".
This module tests if the code compiles and play nice with \f(CW\*(C`Test::Simple\*(C'\fR modules.
.PP
Another good practice this module can test is to \*(L"use strict;\*(R" in all perl files.
.PP
By setting a minimum test coverage through \f(CW\*(C`all_cover_ok()\*(C'\fR, a code author
can ensure his code is tested above a preset level of \fIkwality\fR throughout the development cycle.
.PP
Along with Test::Pod, this module can provide the first tests to setup for a module author.
.PP
This module should be able to run under the \-T flag for perl >= 5.6.
All paths are untainted with the following pattern: \f(CW\*(C`qr|^([\-+@\ew./:\e\e]+)$|\*(C'\fR
controlled by \f(CW$Test::Strict::UNTAINT_PATTERN\fR.
.SH "FUNCTIONS"
.IX Header "FUNCTIONS"
.ie n .SS "syntax_ok( $file [, $text] )"
.el .SS "syntax_ok( \f(CW$file\fP [, \f(CW$text\fP] )"
.IX Subsection "syntax_ok( $file [, $text] )"
Run a syntax check on \f(CW$file\fR by running \f(CW\*(C`perl \-c $file\*(C'\fR with an external perl interpreter.
The external perl interpreter path is stored in \f(CW$Test::Strict::PERL\fR which can be modified.
You may prefer \f(CW\*(C`use_ok()\*(C'\fR from Test::More to syntax test a module.
For a module, the path (lib/My/Module.pm) or the name (My::Module) can be both used.
.ie n .SS "strict_ok( $file [, $text] )"
.el .SS "strict_ok( \f(CW$file\fP [, \f(CW$text\fP] )"
.IX Subsection "strict_ok( $file [, $text] )"
Check if \f(CW$file\fR contains a \f(CW\*(C`use strict;\*(C'\fR statement.
\&\f(CW\*(C`use Moose\*(C'\fR and \f(CW\*(C`use Mouse\*(C'\fR are also considered valid.
.PP
This is a pretty naive test which may be fooled in some edge cases.
For a module, the path (lib/My/Module.pm) or the name (My::Module) can be both used.
.ie n .SS "warnings_ok( $file [, $text] )"
.el .SS "warnings_ok( \f(CW$file\fP [, \f(CW$text\fP] )"
.IX Subsection "warnings_ok( $file [, $text] )"
Check if warnings have been turned on.
.PP
If \f(CW$file\fR is a module, check if it contains a \f(CW\*(C`use warnings;\*(C'\fR or \f(CW\*(C`use warnings::...\*(C'\fR
or \f(CW\*(C`use Moose\*(C'\fR or \f(CW\*(C`use Mouse\*(C'\fR statement.
If the perl version is <= 5.6, this test is skipped (\f(CW\*(C`use warnings\*(C'\fR appeared in perl 5.6).
.PP
If \f(CW$file\fR is a script, check if it starts with \f(CW\*(C`#!...perl \-w\*(C'\fR.
If the \-w is not found and perl is >= 5.6, check for a \f(CW\*(C`use warnings;\*(C'\fR or \f(CW\*(C`use warnings::...\*(C'\fR
or \f(CW\*(C`use Moose\*(C'\fR or \f(CW\*(C`use Mouse\*(C'\fR statement.
.PP
This is a pretty naive test which may be fooled in some edge cases.
For a module, the path (lib/My/Module.pm) or the name (My::Module) can be both used.
.ie n .SS "all_perl_files_ok( [ @directories ] )"
.el .SS "all_perl_files_ok( [ \f(CW@directories\fP ] )"
.IX Subsection "all_perl_files_ok( [ @directories ] )"
Applies \f(CW\*(C`strict_ok()\*(C'\fR and \f(CW\*(C`syntax_ok()\*(C'\fR to all perl files found in \f(CW@directories\fR (and sub directories).
If no <@directories> is given, the starting point is one level above the current running script,
that should cover all the files of a typical \s-1CPAN\s0 distribution.
A perl file is *.pl or *.pm or *.t or a file starting with \f(CW\*(C`#!...perl\*(C'\fR
.PP
If the test plan is defined:
.PP
.Vb 2
\&  use Test::Strict tests => 18;
\&  all_perl_files_ok();
.Ve
.PP
the total number of files tested must be specified.
.PP
You can control which tests are run on each perl site through:
.PP
.Vb 4
\&  $Test::Strict::TEST_SYNTAX   (default = 1)
\&  $Test::Strict::TEST_STRICT   (default = 1)
\&  $Test::Strict::TEST_WARNINGS (default = 0)
\&  $Test::Strict::TEST_SKIP     (default = []) "Trusted" files to skip
.Ve
.ie n .SS "all_cover_ok( [coverage_threshold [, @t_dirs]] )"
.el .SS "all_cover_ok( [coverage_threshold [, \f(CW@t_dirs\fP]] )"
.IX Subsection "all_cover_ok( [coverage_threshold [, @t_dirs]] )"
This will run all the tests in \f(CW@t_dirs\fR
(or current script's directory if \f(CW@t_dirs\fR is undef)
under Devel::Cover
and calculate the global test coverage of the code loaded by the tests.
If the test coverage is greater or equal than \f(CW\*(C`coverage_threshold\*(C'\fR, it is a pass,
otherwise it's a fail. The default coverage threshold is 50
(meaning 50% of the code loaded has been covered by test).
.PP
The threshold can be modified through \f(CW$Test::Strict::COVERAGE_THRESHOLD\fR.
.PP
You may want to select which files are selected for code
coverage through \f(CW$Test::Strict::DEVEL_COVER_OPTIONS\fR,
see Devel::Cover for the list of available options.
The default is '+ignore,\*(L"/Test/Strict\eb\*(R"'.
.PP
The path to \f(CW\*(C`cover\*(C'\fR utility can be modified through \f(CW$Test::Strict::COVER\fR.
.PP
The 50% threshold is a completely arbitrary value, which should not be considered
as a good enough coverage.
.PP
The total coverage is the return value of \f(CW\*(C`all_cover_ok()\*(C'\fR.
.SH "CAVEATS"
.IX Header "CAVEATS"
For \f(CW\*(C`all_cover_ok()\*(C'\fR to work properly, it is strongly advised to install the most recent version of Devel::Cover
and use perl 5.8.1 or above.
In the case of a \f(CW\*(C`make test\*(C'\fR scenario, \f(CW\*(C`all_perl_files_ok()\*(C'\fR re-run all the tests in a separate perl interpreter,
this may lead to some side effects.
