Joe Witt commented on NIFI-14659:
---------------------------------
The param context just lets you define params but they can be used in many
areas. I think it shows impacted components and you can link to them. But
verification/validation is definitely available on processors and controller
services and they would use such params like passwords/etc..
> allow the connection validation test before using it in Processor.

> The below is from the Parameter Contexts. Currently, it allows the
> definition. But it does not allow connection testing.
>
> Thus, when you hit an issue, like invalid password, you will need to identify
> the processor.
> The ideal way is to validate connection at the time it is defined.
