CMS Assessment Model - Information - Functional weight - Number of Decision Points Definition

 This page gives the Functional weight - Number of Decision Points Definition.

Definition

The Number of Decision Points is the sum of all artifact's Cyclomatic Complexity of the selected context. This "Total Cyclomatic Complexity" provides a useful and complementary evaluation of the application functional size based on the number of decision/control flow statements in the application's code. An interpretation of this number is the number of test cases one should set up to test all paths through the application. A steep increase of this number would highlight a need for substantively more testing effort.

Cyclomatic complexity is processed by the Metric Assistant (MA) and it computes the number of the linearly independent paths, a lower bound of all execution paths ignoring multiple iterations.

Below is the list of categories considered by the MA during the computation of cyclomatic complexity:

1. IF
2. ELSIF
3. AND OR
4. CASE
5. CATCH
6. CONTINUE
7. DO WHILE
8. FOR
9. TRY
10. WHILE
