But Imagine if you should guarantee not only that the filters work, but that they’re appropriately arrange and applied to individual motion approaches? What in order to refactor some API code you have already got to reap the benefits of the filters I just confirmed, and you want to ensure the API continue to behaves effectively if you’re concluded? That calls for integration testing. Fortuitously, ASP.Internet Core consists of some great help for quick, easy integration tests.
In this case, the procedure stream Usually executes the filters in ascending purchase usually means from decreased buy to higher purchase. We are going to setup the get house exploitation on the creator parameter.
The OnActionExecuted approach operates following the motion process and will see and manipulate the outcomes of the action throughout the ActionExecutedContext.Result residence. ActionExecutedContext.Canceled will probably be established to true If your motion execution was short-circuited by A further filter.
Upcoming, we must sign-up the Logger Assistance into your created-in dependency injection container.

It is possible to override the designed-in ResultFilterAttribute to create result filters. The AddHeaderAttribute course demonstrated earlier mentioned is an illustration of a final result filter.
Handle Validation: Equally, it checks the Deal with home and provides a model mistake if it’s null or whitespace.
