This is similar to the question asked a few days ago - I attach the 
reply I sent then.

In short, I'd recommend you record a typical scenario, and then add a 
loop to the __call__ method so that the searches are repeated appropriately.

The cookies are deliberately reset at the beginning of the __call__
method. Do something like:

class TestRunner:
def __call__(self):
# first time, log in.

for x in range(0, 100):

statistic addlong function problem


Hi
I try to use this function :

def htmlAnalysisReport(resp,writeInFile,report):
	if resp.statusCode > 300:
		grinder.statistics.addLong("userLong0",1)
		grinder.statistics.success=0
	if HttpResponseUtil.getInstance().isValid(resp.text,erreursHTML) == 0:
		#writeToFile(resp.text)	
		grinder.statistics.addLong("userLong1",1)
		grinder.statistics.success=0			
	
	if report == 1:
		grinder.statistics.report()
	
	if writeInFile == 1:
		writeToFile(resp.text)

i have the following message. I think it's an attribute problem but i don't
know how to resolve it.

Aborted run due to Jython exception "AttributeError: addLong" whilst
invoking test runner
AttributeError: addLong

Could you help me ?
i Think i did the goos import at the begining of the script.
Thanks a lot.

The statistics API changed in beta31. If you derived the above by 
working from current documentation, please let me know.

Your scripts should read something like:

    grinder.statistics.forLastTest.addLong("userLong0", 1)
    grinder.statistics.forLastTest.success = 0
    # etc.

See 
http://grinder.sourceforge.net/g3/script-javadoc/net/grinder/script/Statistics.html#getForLastTest()

You can make this simpler with:
    stats = grinder.statistics.forLastTest
    stats.addLong("userLong0", 1)
    stats.success = 0

Stopping a worker thread in script

Hi,

I’m trying to raise an exception in my test script to stop a worker thread.

As sort of a shot in the dark, I’ve tried something like this:

if (self.vuser.error == 1):

raise ScriptExecutionException, "Server returned error"

Now, this does seem to throw an exception but after that it keeps going on instead of stopping.

Does anyone have any suggestions?

Thanks,

Steve

There isn't a public mechanism to shut down an individual thread. 
Throwing most exceptions will cause The Grinder to log the problem and 
start the next run using that thread. However, there is an undocumented 
way to terminate a single thread (which may or may not be supported in 
future versions) - throw a net.grinder.util.Sleeper.ShutdownException.

If you think this is an important feature for The Grinder, please open a 
feature request.

Regards,

- Phil

Re: How to configure grinder to make sql querys

Grinder enables you to write scripts that call java classes, including
JDBC the java database connection method.

Grinder is a load generator, so we assume you are trying to load test
some or all of your application. To do this you will need to capture the
SQL that the application is generating for the workflow that your are
interested in. How to do this depends on your database, but there is
usually a way of tracing.

Once you have the SQL code it can be used in a Grinder script, using
JDBC calls. If you follow the jdbc.py example (examples\jdbc.py) you
should have some success.  Your will need the JDBC driver for your
database on to the CLASSPATH used to launch the grinder agent.

My advice is to make a batch file to startup the grinder agent and set
the JDBC library for your database on the CLASSPATH that you set in the
batch file.
