Re: [wtp-dev] Performance tests
|
Naci,
Thanks for the response. I want to get some performance tests created for
WTP, but am wondering how these testcases should be packaged. I've a couple
of ideas, but want to hear from other people.
Approach 1. Follow what the Platform project is doing... Create a
"performance" source folder in existing tests plugins. Package these
performance testcases into their own test suite and create a "performance"
ant target in test.xml. So, performance tests are run exactly like
non-performance tests except that you need to pass in the "performance"
target in the build/test scripts. I think this approach is a little messy
because tests plugins that solely consist of non-performance testcases are
required to specify a dummy/empty "performance" target.
<target name="performance">
</target>
Likewise, pure performance plugins need to specify a dummy/empty
non-performance target (missing target can result in build breaks)...
Approach 2. I suggest we make a better seperation between performance tests
and non-performance tests by adding a "performance" folder to the CVS
structure and put performance plugins in that folder.
/home/webtools
/wst
/components
/server
/features
/plugins
/tests
/peformance
Then create features/map files/build configuration files for these
performance plugins. Any suggestions/comments/ideas?
Thanks,
Jeff

Currently, yes. However, there are no performnace test committed yet.

No, but I would be interested in hearing more. The build machines is an
IBM x-series xeon with 2 GB ram and red hat linux. It seems to do well
with builds (i.e. the utilization is still very low). It sounds too
radical to me to reboot a machine to have a "reset". Linux should do a
good job managing these issues. However, the build machine is rebooted
only a few times a month so it is likely that there are some issues for
performance testing. Unfortunately, we (eteration) will not be able to
dedicate a seperate machine for perf-tests only.

Currently, there are no documents beyond that of base eclipse. But, please
do this. It will be very valuable.
