39 This provides an alternate for Net::DBus::Object to enable bus objects
40 to be quickly mocked up, thus facilitating creation of unit tests for
41 services which may need to call out to objects provided by 3rd party
42 services on the bus. It is typically used as a companion to the
43 Net::DBus::MockBus object, to enable complex services to be tested
44 without actually starting a real bus.

46 !!!!! WARNING !!!
47
48 This object & its APIs should be considered very experimental at this
49 point in time, and no guarentees about future API compatability are
50 provided what-so-ever. Comments & suggestions on how to evolve this
51 framework are, however, welcome & encouraged.

54 my $object = Net::DBus::Test::MockObject->new($service, $path, $inter‐
55 face);
56 Create a new mock object, attaching to the service defined by the
57 $service parameter. This would be an instance of the
58 Net::DBus::Service object. The $path parameter defines the object
59 path at which to attach this mock object, and $interface defines
60 the interface it will support.
61
62 my $service = $object->get_service
63 Retrieves the Net::DBus::Service object within which this object is
64 exported.
65
66 my $path = $object->get_object_path
67 Retrieves the path under which this object is exported
68
69 my $msg = $object->get_last_message
70 Retrieves the last message processed by this object. The returned
71 object is an instance of Net::DBus::Binding::Message
72
73 my $sig = $object->get_last_message_signature
74 Retrieves the type signature of the last processed message.
75
76 my $value = $object->get_last_message_param
77 Returns the first value supplied as an argument to the last pro‐
78 cessed message.
79
80 my @values = $object->get_last_message_param_list
81 Returns a list of all the values supplied as arguments to the last
82 processed message.
83
84 $object->seed_action($interface, $method, %action);
85 Registers an action to be performed when a message corresponding to
86 the method $method within the interface $interface is received. The
87 %action parameter can have a number of possible keys set:
88
89 signals
90 Causes a signal to be emitted when the method is invoked. The
91 value associated with this key should be an instance of the
92 Net::DBus::Binding::Message::Signal class.
93
94 error
95 Causes an error to be generated when the method is invoked. The
96 value associated with this key should be a hash reference, with
97 two elements. The first, "name", giving the error name, and the
98 second, "description", providing the descriptive text.
99
100 reply
101 Causes a normal method return to be generated. The value asso‐
102 ciated with this key should be an array reference, whose ele‐
103 ments are the values to be returned by the method.
104
106 It doesn't completely replicate the API of Net::DBus::Binding::Object,
107 merely enough to make the high level bindings work in a test scenario.
