NAME

       Pod::Tests - Extracts embedded tests and code examples from POD

SYNOPSIS

         use Pod::Tests;
         $p = Pod::Tests->new;

         $p->parse_file($file);
         $p->parse_fh($fh);
         $p->parse(@code);

         my @examples = $p->examples;
         my @tests    = $p->tests;

         foreach my $example (@examples) {
             print "The example:  '$example->{code}' was on line ".
                   "$example->{line}\n";
         }

         my @test_code         = $p->build_tests(@tests);
         my @example_test_code = $p->build_examples(@examples);

DESCRIPTION

       This is a specialized POD viewer to extract embedded tests and code examples from POD.  It
       doesn't do much more than that.  pod2test does the useful work.

   Parsing
       After creating a Pod::Tests object, you parse the POD by calling one of the available
       parsing methods documented below.  You can call parse as many times as you'd like, all
       examples and tests found will stack up inside the object.

   Testing
       Once extracted, the tests can be built into stand-alone testing code using the
       build_tests() and build_examples() methods.  However, it is recommended that you first
       look at the pod2test program before embarking on this.

   Methods
   new
         $parser = Pod::Tests->new;

       Returns a new Pod::Tests object which lets you read tests and examples out of a POD
       document.

   parse
         $parser->parse(@code);

       Finds the examples and tests in a bunch of lines of Perl @code.  Once run they're
       available via examples() and testing().

   parse_file $file
         $parser->parse_file($filename);

       Just like parse() except it works on a file.

   parse_fh $fh
         $parser->parse_fh($fh);

       Just like parse() except it works on a filehandle.

   tests
         @testing  = $parser->tests;

       Returns the tests found in the parsed POD documents.  Each element of @testing is a hash
       representing an individual testing block and contains information about that block.

         $test->{code}         actual testing code
         $test->{line}         line from where the test was taken

   examples
         @examples = $parser->examples;

       Returns the examples found in the parsed POD documents.  Each element of @examples is a
       hash representing an individual testing block and contains information about that block.

         $test->{code}         actual testing code
         $test->{line}         line from where the test was taken

   build_tests
         my @code = $p->build_tests(@tests);

       Returns a code fragment based on the given embedded @tests.  This fragment is expected to
       print the usual "ok/not ok" (or something Test::Harness can read) or nothing at all.

       Typical usage might be:

           my @code = $p->build_tests($p->tests);

       This fragment is suitable for placing into a larger test script.

       NOTE Look at pod2test before embarking on your own test building.

   build_examples
         my @code = $p->build_examples(@examples);

       Similar to build_tests(), it creates a code fragment which tests the basic validity of
       your example code.  Essentially, it just makes sure it compiles.

       If your example has an "example testing" block associated with it it will run the the
       example code and the example testing block.

EXAMPLES

       Here's the simplest example, just finding the tests and examples in a single module.

         my $p = Pod::Tests->new;
         $p->parse_file("path/to/Some.pm");

       And one to find all the tests and examples in a directory of files.  This illustrates
       building a set of examples and tests through multiple calls to parse_file().

         my $p = Pod::Tests->new;
         opendir(PODS, "path/to/some/lib/") || die $!;
         while( my $file = readdir PODS ) {
             $p->parse_file($file);
         }
         printf "Found %d examples and %d tests in path/to/some/lib\n",
                scalar $p->examples, scalar $p->tests;

       Finally, an example of parsing your own POD using the DATA filehandle.

         use Fcntl qw(:seek);
         my $p = Pod::Tests->new;

         # Seek to the beginning of the current code.
         seek(DATA, 0, SEEK_SET) || die $!;
         $p->parse_fh(\*DATA);

   SUPPORT
       This module has been replaced by the newer Test::Inline 2. Most testing code that
       currently works with "pod2test" should continue to work with the new version. The most
       notable exceptions are "=for begin" and "=for end", which are deprecated.

       After upgrading, Pod::Tests and "pod2test" were split out to provide a compatibility
       package for legacy code.

       "pod2test" will stay in CPAN, but should remain unchanged indefinately, with the exception
       of any minor bugs that will require squishing.

       Bugs in this dist should be reported via the following URL. Feature requests should not be
       submitted, as further development is now occuring in Test::Inline.
