SUnit Validation was originally conceived by Andres Valloud as a framework for instantaneous feedback on data consistency in the GUI. The framework brilliantly solves the classical problem of handling user inputs in the event that they do not make sense in the model. As envisioned initially, validators factor out repetitive checks that are usually found in the presentation layer. However, the experience has shown that validators are extremely helpful in identifying and solving a wide range of problems. The talk will summarize the experience of introducing heavy validations in a simulation system that has been successful for more than ten years in the Petroleum Industry. That includes new uses of the framework for the GUI, and applications to other areas as model diagnosis, validation of data imported from (and linked to) external sources, version upgrading, naming services, object deletion, SUnit testing, debugging support and automatic source code QA.
