4.updateAuditTrail:
This
service exposes audit trail functionality to allow client systems to write audit
trail
information
for VAS Purchases. This service uses information
in JSON message format which is
updated
in audit trial table of Online banking system. This helps to keep track of
all the
transactions
performed and helps to troubleshoot in case of transaction failure.
5.updateVASGatewayForPurchase:
This
service sends the request to the
third party which process the request and credit the
amount
to the cell. The process from the third party and the actual service
provider is out of
scope
as its already in production and is used by other banks. To keep the seamless
transaction between
the third party and the actual service provider is the responsibility
of third
party
as they have their own contracts for the same. Teams responsibility was to test
the
message
is converted in the format which is expected by the third party. This is done
by
validating
the logs which keep track of the message converted and details around what
message
is send to them.
6.sendVASCommunicationToClient:
Once the transaction is successful / failed
notification will be send to the client of the
same
in the preferred mode which client had already set in his online banking
profile. This is
done
again by another third party. This is out of scope as the same is already in
production for
different
client notifications for transactions. Responsibility over here is to test the
message is
delivered
to Document Services Message Queue (DSMQ) by validating in audit database of DSMQ.
Client Notification from ESB to DocServices
Message which is send from BPM via ESB to doc
services which delivers the notification to the client
Message which is converted, send from ESB to doc
services
Client
Notification DocServices database validation
Audit tables of doc services which processes the message and send it to
the third party so the same can be delivered to banking client
Service Virtualization of Third
Party to continue testing
The
biggest challenge for testing was unavailability of third party services,
environment constraint, as they have Development, Testing and Production were
as we have Development, Testing, Staging/UAT and Production. Because of this
testing was delayed. All the other systems were under control and within bank.
Due to this different team were impacted like development, Service testing
team, functional testing team and also the delivery dates for the project to Go
Live. Each time the messages were to be confirmed with the third party team
that they have received and consumed the messages successfully. This was a
bottle neck as the communication was through call/mail and the teams have to
wait till confirmation received. To overcome this, it was decided to virtualize
the third party system to continue development and testing. CA LISA was the
identified tool used to virtualize the third party service.
The communication between ESB and 3rd Party was
using message queue. ESB used to convert the message as per third party format
and post the message to outbound queue which used to be processed and placed at
third party inbound queue. The response was also in the same format from third
party queue to ESB inbound queue. To make the transaction seamless and without
any hiccups the transaction was virtualized. Proxy queues were created where
the LISA Virtualization recorder was placed which used to read the message and
later pass to outbound queue and in same way recording was done to incoming
message/response from third party. Once all the transaction was recorded the
queue details were changed and virtual service was deployed in LISA VSE all the
messages were processed with virtual service and response was sent back. This
helps the team to continue with their development and testing and all the
services and transaction within the bank environment were tested thoroughly and
were ready for deployment. Few rounds of tested was also done with the third
party to confirm the messages are processed as expected.
