How the assumptions of logistic regression tested in SAS and how violations are addressed?

Violations are not addressed within SAS, that's a statistical process that you need to determine based on your data.

The assumptions behind logistic regression are fairly simple:

In practice, analysts use regression diagnostics (often graphs) and goodness-of-fit tests to determine whether the model fits the data and whether the data exhibit characteristics that potentially violate the assumptions of the model.
