here is a tutorial I wrote for the junit sampler
http://svn.apache.org/repos/asf/jakarta/jmeter/trunk/xdocs/usermanual/junitsampler_tutorial.pdf
basically, to use oneTimeSetup, you have to create a threadgroup and place
all your oneTimeSetUp calls in that thread group. the threadGroup should be
at the top and only run once with 1 thread. Then the actual test methods
should be placed in a separate thread group.
when you select "oneTimeSetUp" as the test method, you have to make sure to
check "do not call setUp". Since JMeter is a multi-threaded environment,
it's necessary to place oneTimeSetUp/oneTimeTearDown in a threadgroup with 1
thread and 1 iteration.
hope that helps
