16. Lec 10 Integration Testing- 16 CSCE 747 Fall 2013 New and Extended Concepts  Definition: A source node in a program is a statement at which program execution begins or resumes.  Definition: A sink node in a program is a statement at which program execution stops.  Definition: A module execution path is a sequence of statements that begins with a source node and ends with a sink node, with no intervening sink nodes. Jorgensen, Paul C. Software Testing A Craftsman Approach

17. Lec 10 Integration Testing- 17 CSCE 747 Fall 2013  Definition: A message is a programming language mechanism by which one unit transfers control to another unit.  Definition: An MM-Path is an interleaved sequence of module execution paths and messages. Jorgensen, Paul C. Software Testing A Craftsman Approach

19. Lec 10 Integration Testing- 19 CSCE 747 Fall 2013  Definition: Given a set of units, their MM- Path graph is the directed graph in which nodes are module execution paths and edges correspond to messages and returns from one unit to another.
