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);
