JRUnit Benchmark object model

timfox Oct 19, 2005 4:09 AM

Hi-

It's my understanding that a Benchmark has a set of BenchmarkExecutions which happen on a certain date/time and contain a set of BenchmarkMeasures.

For simple benchmarks, e.g. record elapsed time to do X this seems to work well, and allows you to chart benchmark evolution vs time.

Some of the "benchmarks" (I don't know if this is the right word) have multi-dimensional measures, i.e. not a simple key-value pair.

E.g. for some of the scalability measurements in JMS, I measure elapsed time to do X, then vary number of jms sessions, and see how X varies.

Then for that execution, I have several measurements:

jms_sessions =1, X = 2000
jms_sessions=2, X = 1500
jms_sessions=3, X = 1250

I.e. the execution data represents a curve rather than a point.

(I think want to be able to then plot this on a chart - but that's a different story).

Does JRUnit support this?

You can add 'measures' at any point within your code. These can be any numeric value with any string as the identifier. However, it doesn't handle anything more complex than this.

I am not sure I fully understand what you are looking for. For doc on jrunit, which pretty much covers everything it can do, can reference http://labs.jboss.com/portal/index.html?ctrl:id=page.default.freezone&project=jrunit&page=docs+index.html or the JBW presentation at http://www.jboss.com/elqNow/elqRedir.htm?ref=http://www.jboss.com/pdf/jbw_barc/core_infra/jboss_jrunit.pdf.
