ST-REL-006 - Infinite Loop

Rule ID: ST-REL-006

Scope: Activity

Description​

This rule identifies potential infinite loop sequences in a Flowchart. It checks for self connecting nodes or connections that point back and can create an infinite loop. However, the rule doesn't identify such potential loops where Invoke Workflow activity is used to create a loop.

An infinite loop is defined as a sequence of instructions that loops endlessly, either due to the loop having no terminating condition, having one that can never be met, or one that causes the loop to start over.

The rule only checks connections, not all the conditions in the flowchart. For example, having both a static value in a decision that is true and one that is false will trigger the rule:

The rule's Default action is set to Warning.

Recommendation​

If an infinite loop was found, make sure to add a termination condition. If the loop is intended, then document the code and let users know.
