### Cause effect graphing technique

1. 1. Cause Effect Graphing Technique
2. 2. Cause-effect graphs in black box testing• Captures the relationships between specific combinations of inputs (causes) and outputs (effects) –Deals with specific cases, –Avoids combinatorial explosion –Explore combinations of possible inputs• Causes/effects are represented as nodes of a cause effect graph• The graph also includes a number of intermediate nodes linking causes and effects
3. 3. Cause effect graph, an example• File management: • If the character of the first column is ‘A’ or ‘B’, and the second column is a number, then the file is considered updated. • If the first character is erroneous, print message X12 • If the second column is not a number, print message X13 4Proposed by G.

4. 4. Cause effect graph: Decision Table 5Proposed by G. J. Mayers
5. 5. Cause effect graph: MethodologyTest technique based on cause effect graph consists in the following steps:1.Decompose the unit to be tested, If it has many functionalities2.Identify the causes3.Identify the effects4.Establish the graph of relations between causes and effects5.Complete the graph by adding constraints between causes and effects6.Convert the graph to a decision table7.Produce a test per line after simplification of the table 6Proposed by G.
