Beanshell to get random csv value

[CharekC <ch...@gmail.com>]

I've been looking at beanshell to get random csv file values.
I have the following code:

ArrayList csv_array=null;

String getCSV_Value() {

        if (csv_array==null)
                // initialize csv_array from file

        if (csv_array.size()>0)
                //return random value from csv_array
        else
                // return error_value

}

I'm running into the problem where each call of
${__BeanShell(getCSV_Value())} initializes the csv_array.
I've tried the following:
1. renamed getCSV_Value() to execute()
2. tried public static ArrayList csv_array=null;
3. Placed the code and referenced it in jmeter.properties
beanshell.function.init=
beanshell.init.file=
       
So how can one make csv_array global and the getCSV_Value() method
synchronized? (Jmeter 2.3RC4)

Thanks

Each occurrence of a function in a test plan is a separate instance.

Make sure that you only have one function call; you can put this in a
user parameters pre-processor so that each sampler gets a new value.

However, I would probably not do it this way; it's a waste of
resources to do the randomisation at run-time if it can be avoided.
Also, if the file is big, it will take a lot of memory.

I'd create a pre-randomised file and use CSV Dataset or
__StringFromFile() to read it.
