NAME

Class::PObject::Test - Base test framework for Class::PObject drivers

SYNOPSIS

    package Class::PObject::Test::MyTest;
    require Class::PObject::Test;
    @ISA = ('Class::PObject::Test');

    sub run {
        my $self = shift;

        my $driver      = $self->{driver};
        my $datasource  = $self->{datasource};

        # perform your tests using $driver and $datasource

    }

ABSTRACT

    Class::PObject::Test is a base testing framework for Class::PObject drivers.

DESCRIPTION

Class::PObject::Test is used as a base class by test libraries, and provides two methods, new() and run(). Subclasses of Class::PObject::Test are expected to override run().

IS THIS WAY OF TESTING NECESSARY

Same sets of tests must be performed for every single driver available to ensure all the drivers are compatible. That's why, instead of putting redundant chunks of codes in multiple t/*.t files, we created a library, which can run same tests for different drivers.

For example, to run some basic/core tests on file driver, we do:

    # t/01basic_file.t
    use Class::PObject::Test::Basic;
    $t = new Class::PObject::Test::Basic('file', './data');
    $t->run()

To run these same set of tests for mysql driver, for example, we can do:

    # t/02basic_mysql.t
    use Class::PObject::Test::Basic;
    $t = new Class::PObject::Test::Basic('mysql', {Handle=>$dbh});
    $t->run()

and so on.

This will ensure that same exact tests are run for every driver.

METHODS

  • new($driver, $datasource) - constructor method. Accepts two arguments, $driver and $datasource. You can access these object attributes from within run() to generate pobjects for testing purposes.

  • run() - runs the tests. You can use Test::More - testing library for running the tests. A very simple test can look like:

        sub run {
            my $self = shift;
    
            pobject ClassName => {
                columns => ['id', 'a', 'b', 'c'],
                driver  => $self->{driver},
                datasource => $self->{datasource}
            };
            ok(1);
    
            my $obj = ClassName->new();
            ok($obj);
    
            $obj->a('A');
            $obj->b('B');
    
            ok($obj->save)
        }

    If you want to write a special test library, you are expected to do a little more than that, because Class::PObject::Test::Basic already performs most of the Class::PObject driver functionality.
