When testing if a connection for a datasource can be obtained through the Admin-console, the whole UI for that operation is confusing and misleading. User tends to interpret the results of the "Test Connection" under "Operation History" as the result if the connection has been successfully obtained or not, where in reality that section is just reporting that the operation "Test Connection" has been executed successfully, and nothing to do with the connection is obtained or not. The actual result for that is in the section below called "Selected Operation History Item".
This is confusing to operational admins looking at this UI to test a connection. In fact, this would mislead them to look at the wrong section and proceed thinking the connection has been obtained when it's not, and could possibly cause serious production ramifications. The UI should be re-worked and be more intuitive and clear.
