Extended use cases describe scenarios that will only occur in a specific situation if a certain condition is met. Therefore, extension associations indicate the need for a test to determine whether or not it is necessary to also execute the extended use case. Extension relationships represent events that do not always occur, which does not mean that they are uncommon. Identifies a point in the behavior of a use case from which this behavior can be extended by the behavior of another use case, if the condition for this to occur is met.
