> Key: TINKERPOP-717
> URL: https://issues.apache.org/jira/browse/TINKERPOP-717
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.0.2-incubating
> Reporter: Matt Frantz
>
> Consider a step that allows specifying a traversal that must be proven. In
> conjunction with a strategy that removes such steps for "production", this
> would provide the "assert" capability in many languages.
> {code}
> GraphTraversal assert(Traversal t)
> {code}
> The logic would be that if {{t}} does not produce a traverser, then an
> assertion exception would be raised.
> We probably can't call it {{assert}} because it is a reserved word in many
> languages.
