Hi,
I'm a new developer for WMB (using 6.1.0.3) and I wanna know if there is a way to create unit testing with it, or any type of automatic tests.
I'm currently using the mbtest files to do some tests, but it requires a lot of pre-configuration on each machine that it is used to develop. Let´s say, I changed my message set, and I cant detect the points where it affects directly or some kind of this.
How do you deal with this type of concerns in development process? There practices to do tests with WMB, or the only way is through toolkit and do it manually? |

We use JUnit.

Are you talking about impact analysis? Or have I misunderstood?

We do early testing (like does it actually work) with RFHUtil, unit / integration test with JUnit & the non-functional test team use something called Fitness about which I know nothing, except it generates so many messages it brings down their rather underpowered box on a regular schedule.

Vitor thanks for response.
How do you use JUnit, I was looking for something related to development WMB with Junit, but didn find.
I´m considering testing message flows too, I dont know how to do it or if its possible.
Not necessarilly impact analysis. Currently, I´m just considering the test parts. I just wanna run a group of tests and see if it failed on some point of the flow/code. Because, to test I need a WMQ/WMB/Database just to test some logic points. Its too much for simple tests.. because with this I think that I am doing a Integration tests and not a unit test.
You do unit tests with an external application, or do you test internally? Its a project inside of WMB project?
Do you have some references? |

Personally - slowly and very, very carefully. It's outside my comfort zone, being contaminated with Java.

That's what we're doing - there's JUnit "stuff" which you "Run as JUnit" inside the WMB toolkit. There's a great grinding, a lot of things happening and the little bar goes red or green.
You'll notice my familiarity with both this tool and it's terms. 
Looks like a lot of Java with example messages and responses built into it to me. I'm told it's far more complicated than that, and am disinclined to get further involved. I'm sure one of the less Java-phobic posters on the forum will be along in a minute.

Not sure you'll be able to get round that. I'm unaware of a way of testing flows without running them in WMB.

We call it a unit test if we're not talking to a real end point, and an integration test if we are.

We call it a unit test if we're not talking to a real end point, and an integration test if we are. It's all tested internally, but for unit tests it's a dummy application / service / etc rather than a real one.

Technically or politically? It's all run inside Toolkit, or on the servers, and is under the control of the project doing the development.
| fabyos wrote: |

This was all developed in-house as an extension of the JUnit used to test some of the end point applications. I dread to think what they referred to; I consider Java something akin to black magic!!

You could take a look at the IH03 Support Pack. Apart from RFHUTIL, there are other utilities that can send batches of messages (with all your test/errors built in) to the target flows.
OR
You can roll your own.
I use a version of amqsput (a freebie WMQ utility that has the 'C' source supplied) that has been modified to :-
- Read messages from files
- take messages up to 1Mb in size
These are all put into a set of scripts that all me to run sets of tests as required and repeat as often as I need to.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

| SupportPac MA0T can be examined as well. |
