At any time during the construction
of a UML model or diagram, you can check that it complies with the
defined constraints and ensure that no broken cross-model references
exist.
Before you begin
You must have a model open in the
Modeling perspective
and you must enable at least one constraint category in the
Validation preferences.
About this task
There are three levels of model validation severity:
- An error is a critical violation that is not allowed.
- A warning is less severe than an error and indicates a rule violation
that is allowed, but that results in your model being semantically
incorrect.
- An informational message is the least severe form of violation
and indicates a rule that is inconsistent with UML standards but that
does not need to be corrected.
Procedure
- To validate a model, diagram, or model element, right-click
the item; then click Validate. Any
violations are listed in the Problems view.
- To view the subject of a validation error or warning, in
the Problems view, right-click an error or warning;
then click Go To. The involved
model elements are selected in the Project Explorer view.
The list of validation errors is also displayed in the Alerts and Action Items section of the UML
Model Editor.
