NAME

       Lire::Test::Mock - Create mock object

SYNOPSIS

         use Lire::Report;
         use Lire::Test::Mock;
         use Lire::DlfResult;

         my $mock = new Lire::Test::Mock( 'Lire::Report' );
         $mock->set_result( 'timestamp', $time );
         $mock->timestamp(); # will return $time
         $mock->get_calls(); # [ 'timestamp' ]
         $mock->get_invocation( 'timestamp', 0 ); # [ $mock ]

DESCRIPTION

       This class makes it easy to defined mock objects. Mock objects are objects which offers
       the same interface than another object but which do not share its functionality. This
       makes it easier to test objects which requires fixtures which have lots of dependencies.

       The mock object can be used to collect information about calls made on the object. Returns
       value for such method invocation can also be specified.

   new( $class, 'method' => $result, 'method' => $result )
       Creates a new mock object that will wrap $class. Any other keyword arguments will be use
       to initialize the result of methods call. See set_result() for information on how this
       works.

   new_proxy( $class, @constructor_params )
       This creates mock object which for the base $class. A proxy mock object will still monitor
       calls to the object but the real methods will be invoked, unless a result was specified
       using set_result(). Any remaining parameters will be passed to the new() method which
       should be defined in the class.

   new_proxy( $instance )
       Makes a Lire::Test::Mock object which is a clone of $instance.

   is_proxy()
       Returns whether this mock object will proxy to the real methods when no results was
       defined for a specific method.

   get_calls()
       Returns an array reference containing all the methods called on the object.

   invocation_count( $method )
       Returns the number of time $method was called.

   get_invocation( $method, $index )
       Returns the parameter that were given when method $method was called.

   set_result( method => $result, ... )
       This assign the result $result to $method. If $result is a code reference, it will be
       invoked with the same argument than the method to compute the result.

USING MOCK FACTORIES

       Sometime, it is not possible to instatiate a proxy or mock object during fixture setup.
       This will usually happen when the object which we want to track access to is instantiated
       by the method under test.  In these cases, one can use the set_mock_factory() class method
       to change the factory method to one that will return a proxy instance instead of a real
       instance. One should call reset_factories() during tear_down() so that the real factory
       method become directly accessible once again.

   set_mock_factory( $class, %results )
       Make the new() method of package $class returns proxy Lire::Test::Mock instance. The
       created instances will be accessible through the mock_instances() method. Any other
       argument will be passed to the set_result() method when the mock instance is created.

   mock_instances( $class )
       Returns an array reference containing all the instance that were created by the installed
       mock factory in $class. This method will throw an exception if now mock factory was
       installed for class $class.

   reset_factories()
       Removes all mock factories that were set up using set_mock_factory().
