ResultExecutedContext.Exception is going to be established to your non-null value Should the action final result or even a subsequent final result filter threw an exception.
Shifting logic from a controller into attributes is perfect for decreasing code complexity and imposing consistent runtime habits. Sadly, when you run unit exams directly in opposition to your motion techniques, your assessments aren’t going to hold the attribute or filter actions placed on them. This really is by style and design, not to mention you can device exam your filters independent of personal action techniques to be certain they work as developed.
