We currently use LoadRunner for performance testing our web apps, but we also have some server side processes we need to test.

Background:

We call these processes our ‘engines’. One engine receives messages by polling an IBM WebSpere MQ queue for messages. It takes a message off the queue, processes it, and puts the result on an outbound queue. We currently test this engine via a TCL script that reads a file that contains the messages, puts the messages on the inbound queue, then polls the outbound queue for the results.

The other engine receives messages via a web service. The web service writes the message to a table in our database. The engine polls the database table for new messages, takes a message and processes it, and puts the result back into the database. We currently test this engine via a VBScript script that reads a file that contains the messages, sends the message to the web service, then keeps querying the web service for the result unitl it’s ready.

Question:

We’d like to do away with the TCL and VBScript scripts and standardize on LoadRunner so that we have one tool to manage all our performance tests.

  1. I know LoadRunner supports a Web Services protocol ‘out of the box’, but I’m not sure how to use it. Does anyone know of any examples of how to use LoadRunner to test a web service?
  2. Does LoadRunner have a protocol for MQ? Is it possible to use a LoadRunner Vuser to drive load (put messages) into an MQ queue? Would we need to purchase something from HP or some other vendor to do this?

Thanks 🙂

  1. There is an add-in for LoadRunner in the incuded software to interface with MQ series and put the messages directly on the queue. Web services are fully supported also, and VBScript is supported too,perhaps using QTPro for the script and a GUI user in LoadRunner? Colin.
