In essence, Bound Constraints and Invalid Constraints perform similar tasks: they ensure that certain values only or never appear together - making all generated scenarios valid within the model scope. From a different point of view, Bound Constraints and Mutually Bound Constraints actually invalidate many values and Invalid Constraints bind many values, behind the scenes.

"Skip" constraints

"Skip" constraints are only available under the Advanced Mode which is enabled per request (toggle in the top left of the Constraints screen).

"Skip" constraints allow for certain parameters to be excluded from test cases when it is not appropriate for them to appear. It is a faster alternative to the "Not applicable" + Bound Pairs approach. However, as the feature is in the beta stage, please note that there are a couple open defects, specifically around the interaction of "Skip" constraints with the regular ones. So if you encounter any issues, feel free to reach out to Support or avoid skips for the time being.

How to Use Skip Constraints

For example, let’s use this plan below for a flight booking system:

Lastly, you can do a quick review of available options & syntax by clicking the “Usage” button in top-right section of the Advanced Mode:

View a Constraint

Edit a Constraint

To edit a constraint, you need to change view to "bulk" . Then you can edit the constrain type selecting the corresponding operator. 

It is not possible to edit a constrain at the Standard View. In the Standard View you are only allowed to delete and create a new constrain.

Delete a Constraint

To delete a constraint, hover the constraint and select the delete option:
