NAME

Test::TAP::Model - DEPRECATED Use TAP::Harness, TAP::Formatter::HTML

CONTENTS

SYNOPSIS



        use Test::TAP::Model;

        my $t = Test::TAP::Model->new();

        # Test::Harness::Straps methods are available, but they arent enough.
        # Extra book keeping is required. See the run_test method

        # heres a convenient wrapper
        $t = Test::TAP::Model->new_with_tests(glob("t/*.t"));
       
        # thats shorthand for new->run_tests
        $t->run_tests(qw{ t/foo.t t/bar.t });

        # every file is an object (Test::TAP::Model::File)
        my @tests = $t->test_files;

        # this method returns a structure
        my $structure = $t->structure;

        # which is guaranteed to survive serialization
        my $other_struct = do { my $VAR; eval Data::Dumper::Dumper($structure) };

        # the same as $t1
        my $t2 = Test::TAP::Model->new_with_struct($other_struct);



DESCRIPTION

This module is a subclass of Test::Harness::Straps (although in an ideal world it would really use delegation).

It uses callbacks in the straps object to construct a deep structure, with all the data known about a test run accessible within.

It’s purpose is to ease the processing of test data, for the purpose of generating reports, or something like that.

The niche it fills is creating a way to access test run data, both from a serialized and a real source, and to ease the querying of this data.

YEAH YEAH, WHAT IS IT GOOD FOR?

Well, you can use it to send test results, and process them into pretty reports. See Test::TAP::HTMLMatrix.

TWO INTERFACES

There are two ways to access the data in Test::TAP::Model. The complex one, which creates objects, revolves around the simpler one, which for Q&D purposes is exposed and encouraged too.

Inside the object there is a well defined deep structure, accessed as



        $t->structure;



This is the simple method. It is a hash, containing some fields, and basically organizes the test results, with all the fun fun data exposed.

The second interface is documented below in METHODS, and lets you create pretty little objects from this structure, which might or might not be more convenient for your purposes.

When it’s ready, that is.

HASH STRUCTURE

I hope this illustrates how the structure looks.



        $structure = {
                test_files => $test_files,

                start_time => # when the run started
                end_time   => # ... and ended
        };

        $test_files = [
                $test_file,
                ...
        ];

        $test_file = {
                file => "t/filename.t",
                results => \%results;
                events => $events,

                # optional
                pre_diag => # diagnosis emitted before any test
        };

        %results = $strap->analyze_foo();

        $events = [
                {
                        type => "test",
                        num    => # the serial number of the test
                        ok     => # a boolean
                        result => # a string useful for display
                        todo   => # a boolean
                        line   => # the output line

                        # pugs auxillery stuff, from the <pos:> comment
                        pos    => # the place in the test file the case is in

                        time   => # the time this event happenned
                },
                {
                        type => "bailout",
                        reason => "blah blah blah",
                }
                ...,
        ];



That’s basically it.

OBJECT INTERFACE

The object interface is structured around three objects:
Test::TAP::Model A whole run
Test::TAP::Model::File A test script
Test::TAP::Model::Subtest A single case in a test script
Each of these is discussed in it’s respectful manpage. Here’s the whole run:

METHODS

    The said OOP interface

test_files Returns a list of Test::TAP::Model::File objects.
ok
passing
passed
nok
failed
failing Whether all the suite was OK, or opposite.
total_ok
total_passed
total_nok
total_failed
total_percentage
total_ratio
total_seen
total_skipped
total_todo
total_unexpectedly_succeeded These methods are all rather self explanatory and either provide aggregate results based on the contained test files.
ratio An alias to total_ratio.

    Misc methods

new Creates an empty harness.
new_with_struct $struct Adopts a structure. This is how you take a thawed structure and query it.
new_with_tests @tests Takes a list of tests and immediately runs them.
get_tests A method invoked by run to get a list of tests to run.

This is a stub, and you should subclass it if you care.

run This method runs the list of tests returned by get_tests.
run_tests @tests Runs these tests. Just loops, and calls analyze file, with an eval { } around it to catch bail out.
run_test $test Actually this is the part which does eval and calls start_file and analyze_file
start_file This tells Test::TAP::Model that we are about to analyze a new file.

This will eventually be moved into an overridden version of analyze, I think.

Consider it’s existence a bug.

log_event This logs a new event with time stamp in the event log for the current test.
latest_event Returns the hash ref to the last event, or a new one if there isn’t a last event yet.
file_class This method returns the class to call new on, when generating file objects in test_files.
structure This method returns the hash reference you can save, browse, or use to create new objects with the same date.
log_time This is an accessor. If it’s value is set to true, any events logged will have a time stamp added.

SERIALIZING

You can use any serializer you like (YAML, Storable, etc), to freeze $obj->structure, and then you can thaw it back, and pass the thawed structure to new_with_struct.

You can then access the object interface normally.

This behavior is guaranteed to remain consistent, at least between similar versions of this module. This is there to simplify smoke reports.

ISA Test::Harness::Straps

Test::TAP::Model is a Test::Harness::Straps subclass. It knows to run tests on it’s own. See the run methods and it’s friends.

However, you should see how run_test gets things done beforehand. It’s a bit of a hack because I’m not quite sure if Test::Harness::Straps has the proper events to encapsulate this cleanly (Gaal took care of the handlers way before I got into the picture), and I’m too lazy to check it out.

VERSION CONTROL
