Construction
|
|
Validation
|
|
Testing
|
|
|
|
Construction will generate some state
|
|
Validation will ensure that everything is kosher
|
|
Tests use combinations of the above to check things
|
|
|
|
##### Example:
|
|
parent = gst_object_get_parent(object);
|
|
|
|
setup:
|
|
create: new object
|
|
action: object = gst_object_new();
|
|
validation: object != NULL, object->parent == NULL, etc
|
|
[cleanup: gst_object_destroy(object);]
|
|
create: new parent
|
|
action: parent = gst_object_new();
|
|
validation: parent != NULL, parent->parent == NULL, etc
|
|
[cleanup: gst_object_destroy(parent);]
|
|
create: set object's parent
|
|
precondition: object->parent == NULL
|
|
action: gst_object_set_parent(object,parent);
|
|
validation: object->parent = parent
|
|
preconditions:
|
|
nothing
|
|
action:
|
|
curparent = gst_element_get_parent(object);
|
|
validaton:
|
|
curparent == object->parent
|
|
curparent == parent
|
|
cleanup:
|
|
nothing
|
|
|
|
|
|
##### Resulting code:
|
|
|
|
///// setup
|
|
// new object
|
|
object = gst_object_new();
|
|
ASSERT(object != NULL);
|
|
ASSERT(object->parent == NULL);
|
|
// new object
|
|
parent = gst_object_new();
|
|
ASSERT(parent != NULL);
|
|
ASSERT(parent->parent == NULL);
|
|
// set object parent
|
|
ASSERT(object->parent == NULL);
|
|
gst_object_set_parent(object,parent);
|
|
ASSERT(object->parent != NULL);
|
|
|
|
///// preconditions
|
|
|
|
///// action
|
|
curparent = gst_element_get_parent(object);
|
|
|
|
///// validation
|
|
ASSERT(object->parent == parent);
|
|
|
|
///// cleanup
|
|
gst_object_destroy(parent);
|
|
gst_object_destroy(object);
