NAME
Net::DBus::Test::MockObject - Fake an object from the bus for unit
testing
SYNOPSIS
use Net::DBus;
use Net::DBus::Test::MockObject;
my $bus = Net::DBus->test
# Lets fake presence of HAL...
# First we need to define the service
my $service = $bus->export_service("org.freedesktop.Hal");
# Then create a mock object
my $object = Net::DBus::Test::MockObject->new($service,
"/org/freedesktop/Hal/Manager");
# Fake the 'GetAllDevices' method
$object->seed_action("org.freedesktop.Hal.Manager",
"GetAllDevices",
reply => {
return => [ "/org/freedesktop/Hal/devices/computer_i8042_Aux_Port",
"/org/freedesktop/Hal/devices/computer_i8042_Aux_Port_logicaldev_input",
"/org/freedesktop/Hal/devices/computer_i8042_Kbd_Port",
"/org/freedesktop/Hal/devices/computer_i8042_Kbd_Port_logicaldev_input"
],
});
# Now can test any class which calls out to 'GetAllDevices' in HAL
....test stuff....
DESCRIPTION
This provides an alternate for Net::DBus::Object to enable bus objects
to be quickly mocked up, thus facilitating creation of unit tests for
services which may need to call out to objects provided by 3rd party
services on the bus. It is typically used as a companion to the
Net::DBus::MockBus object, to enable complex services to be tested
without actually starting a real bus.
!!!!! WARNING !!!
This object & its APIs should be considered very experimental at this
point in time, and no guarantees about future API compatibility are
provided what-so-ever. Comments & suggestions on how to evolve this
framework are, however, welcome & encouraged.
METHODS
my $object = Net::DBus::Test::MockObject->new($service, $path,
$interface);
Create a new mock object, attaching to the service defined by the
$service parameter. This would be an instance of the
Net::DBus::Service object. The $path parameter defines the object
path at which to attach this mock object, and $interface defines the
interface it will support.
my $service = $object->get_service
Retrieves the Net::DBus::Service object within which this object is
exported.
my $path = $object->get_object_path
Retrieves the path under which this object is exported
my $msg = $object->get_last_message
Retrieves the last message processed by this object. The returned
object is an instance of Net::DBus::Binding::Message
my $sig = $object->get_last_message_signature
Retrieves the type signature of the last processed message.
my $value = $object->get_last_message_param
Returns the first value supplied as an argument to the last
processed message.
my @values = $object->get_last_message_param_list
Returns a list of all the values supplied as arguments to the last
processed message.
$object->seed_action($interface, $method, %action);
Registers an action to be performed when a message corresponding to
the method $method within the interface $interface is received. The
%action parameter can have a number of possible keys set:
signals
Causes a signal to be emitted when the method is invoked. The
value associated with this key should be an instance of the
Net::DBus::Binding::Message::Signal class.
error
Causes an error to be generated when the method is invoked. The
value associated with this key should be a hash reference, with
two elements. The first, "name", giving the error name, and the
second, "description", providing the descriptive text.
reply
Causes a normal method return to be generated. The value
associated with this key should be an array reference, whose
elements are the values to be returned by the method.
BUGS
It doesn't completely replicate the API of Net::DBus::Binding::Object,
merely enough to make the high level bindings work in a test scenario.
