[jira] Commented: (DERBY-4429) Let StressMultiTest read Threads and Minutes to run as system property

----------------------------------------

Hi Ole,

I note that other tests use "derby.tests." instead of "derby.test.". Maybe it would be better to agree on a common prefix?
I was also surprised that I didn't get any error messages when I specified derby.tests.debug=true, but I did get  a message when I specified derby.tests.trace=true. It is possible that I have misunderstood the meaning of these properties.
Maybe a warning message should be printed regardless of the values for debug and trace if parsing the input fails?

+1 to commit if the prefix of the property is aligned with the existing one

> Allow StressMultiTest to read System Property "derby.test.ThreadsMinutes" to set the number of threads and minutes testStressMulti should run.
> Example: '-Dderby.test.ThreadsMinutes=33x3'.
> This will set 
> StressMultiTest.THREADS to 33 and
> StressMultiTest.MINUTES to 3.
> This can be utilized to for example
> reduce the time StressMultiTest is run in a tinderbox test: '-Dderby.test.ThreadsMinutes=33x3' and
> increase the load for a specific test: '-Dderby.test.ThreadsMinutes=200x60'.
> The StressMultiTest defaults are as set with '-Dderby.test.ThreadsMinutes=10x10'.
> By default the test suite for StressMultiTest is set to  run in embedded, client and encryption mode, i.e. 3 x the Minutes specified.
