Could a sort of "connection test" be implemented to verify if a "connection definition" specified for a resource adapter (eg: file, google, etc) is working, and can "connect" to the resource it's supposedly pointing to?

Data sources(jdbc) already have this kind of test, and it is quite useful to test if there's any error in their connection definition.

With resource adapters, one must define connection definitions, but it is not possible to test them, independently from later requests/queries (eg: reading data from .csv or .xls files, or oauth web services): one has to build all the chain and really try to get data from the source, using the vdb, hoping everything is correctly defined...

Recently I am struggling with a custom rest oauth2 RA, and I need to define

• security domain (with client id/secret, tokens, auth uri)
• RA using that domain
• a connection definition for the RA accessing the remote data source
• a VDB using the connection definition
• a client using the VDB to try get data in sql form

any step could be wrong, but only the last allows to check if the whole chain is working, or not.

For any error or failure, regular users (like me) can't do anything else than double check everything... a "test connection" button, for the connection definition, would do wonders to simplify setup debug...
