when is a sample not a sample?
Hi,
I am wondering if and how it is possible to exclude the results of a specific sample (or at least disregard it) from the results.
We have a dual stripe system which can be tested in online or offline mode. To automate the decision we can request a status page, and act on the results. Not all our test systems have dual stripes, so the request fails. However, this is a valid situation.
I always want to lookup the status page, but only if it exists and only if it responds a certain way do I want it to affect the test run.
I am finding the situation where it is not available is being recorded as a test failure.
Effectively, I want to perform the request as a pre-processor of another sample, but it seems overkill to write it in java/beanshell/someotherlang code. Is there anything like a HTTP Request pre-processor, or a flag I can set somewhere that says ignore this sample on error?
Thanks in advance,
Charlie

Hi,
Listeners apply to their parent and all samples that are childs from their
parent level down. This is the only way to reduce the scope of a listener:
to add it in a different controller which contains only the samplers you
want to monitor. It is not always possible to do because you still want to
respect a certain sequence of samples sometimes. So when this happens, but
I still want to exclude some of the requests, I add different listeners as
child to every sampler I am interested in.
The only selective conditions available to listeners is success/failure. So
if you fail a request that doesn't meet a condition you can choose to
monitor only those that meet your expectations - but that means increasing
the error rate artificially (which is not a problem, if you only monitor
the successes anyway). Its not elegant, I don't recommend it.
Maybe some plugin does the job, but never searched for it, as I never
needed this scenario to work before.
Cheers,
Adrian S

You can use the Response Assertion to reset the failure flag.
That's used (for example) when checking for 404 responses, which by default
are failures.
Just use an assertion test that's bound to succeed.
