Test cases for LibLarch

For purpose of rewriting parts of LibLarch, there is a small demo at lp:~izidor/gtg/liblarch-demo. It contains liblarch and liblarch-gtk code, unittests and a GUI application for experimenting. A screenshot of the demo application:

The following list of behavior defined by use cases is required:

Test case #1

  • run unit tests

Expected result: Every unit test passes.

Test case #2

  • Load situation form file example-trees/delete-randomly

  • Select all tasks (<CTRL> + A)

  • Press Delete randomly

Expected result: The operation is completed in a reasonable time and without errors in the console (compare by deleting by Delete backwards)

Actual result: Many tracebacks in console, deleting takes a long time.

Test case #3

  • Load situation form file example-trees/test_suite

  • Select any Task X and delete it

Expected result: No warning and the resulting tree like this one: 

==================== Tree ====================
root
 A
 C
  D
 B
 E
  F
==============================================

Test case #4

  • Load situation form file example-trees/test_suite

  • Select any parent of Task X and delete it

Expected result: No warnings and preserve consistency of the tree

Test case #5

  • Load situation form file example-trees/test_suite

  • Press the button Delete DFXBCAE

Expected result: No warnings, the result tree is empty.

Actual result: 

/home/iyo/projekte/liblarch-demo/GTG/gtk/liblarch_gtk/treemodel.py:403: GtkWarning: _gtk_rbtree_reorder: assertion `tree->root->count == length' failed 
  f(*args)

Test case #6

  • Load situation form file example-trees/test_suite

  • Select any task (X or not X) and press Tree high 3 backwards

Expected result: added to tree and preserved consistency of the tree

Actual result: many warnings, e.g 

** (main.py:29964): CRITICAL **: pygtk_generic_tree_model_get_value: assertion `VALID_ITER(iter, tree_model)' failed

** (main.py:29964): CRITICAL **: pygtk_generic_tree_model_get_value: assertion `VALID_ITER(iter, tree_model)' failed

** (main.py:29964): CRITICAL **: pygtk_generic_tree_model_iter_children: assertion `parent == NULL || parent->stamp == PYGTK_GENERIC_TREE_MODEL(tree_model)->stamp' failed

Test case #6

  • Load situation form file example-trees/test_suite

  • Select any task (X or not X) and press Tree high 3 backwards

Expected result: added to tree and preserved consistency of the tree

Actual result: many warnings, e.g 

** (main.py:29964): CRITICAL **: pygtk_generic_tree_model_get_value: assertion `VALID_ITER(iter, tree_model)' failed

** (main.py:29964): CRITICAL **: pygtk_generic_tree_model_get_value: assertion `VALID_ITER(iter, tree_model)' failed

** (main.py:29964): CRITICAL **: pygtk_generic_tree_model_iter_children: assertion `parent == NULL || parent->stamp == PYGTK_GENERIC_TREE_MODEL(tree_model)->stamp' failed

Test case #7

  • Load situation form file example-trees/cycle

Expected result: A traceback: 

Traceback (most recent call last):
  File "./main.py", line 504, in load_from_file
    parent_node.add_child(child)
  File "/home/iyo/projekte/liblarch-demo/GTG/tools/liblarch/tree.py", line 600, in add_child
    toreturn = self.new_relationship(self.get_id(),node_id)

    return self.tree.new_relationship(par,chi)

    "between %s and %s" %(parent_id,child_id))
Exception: Cannot build circular relationshipbetween Child and Parent

  • Press button Print Tree (to see how liblarch see the tree)

Expected result: print the same tree which is shown in liblarch_widget

Actual result: many parent, child nodes and ended by a traceback RuntimeError: maximum recursion depth exceeded in cmp

Test case #8

Same as Test case #7 but load example-trees/cycle2 instead. It is contains indirect recursion (A->B, B->A).
