Hi Steveo,

support for The Grinder 3.1 and 3.2
support for latest versions of PyDev Eclipse plugin

New Features:
Ability to add and pass to script arguments via JVM parameters

What was fixed:
Eclipse 3.4.1 support
Eclipse 3.3 compatibility is broken
Unable to create new Grinder Run Configuration (PyDev 1.4/Grinderstone 2.0.0)
Grinderstone does not launch script (NoSuchMethodError – IpythonPathNature.getProjectSourcePath()Ljava/lang/String)
An internal error occurred during “Launching”

Steveo did you managed to use a datafile to feed a test script? If yes, could you point me some details?

I am new to both The Grinder and GrinderStone. I used the update manager to install GrinderStoner after manually downloading and installing Jython and The Grinder.

I am running the following configuration:

Jython 2.2.1
The Grinder 3.2
Pydev 1.4.6.2788
GrinderStoner 2.0.0
JDK1.5.0_16

After having followed the instructions above I right click on my GoogleHomePageTest.py file (which I created under the /src folder) and click ‘Grinder Run’. Nothing happens, i.e. nothing appears in the console.

When I go into the run configuration context menu and attempt to create a new ‘Grinder Run’ I get the following error message:

Plug-in com.googlecode.grinderstone was unable to load class com.googlecode.grinderstone.debug.ui.GrinderTabGroup

Can someone please help me?

Thanks.

Mark.

So I eventually got all this sorted out. It was a matter of specifying full paths in the config files for grinder.

Ramp up/down is also not so hard, depending how much control you need. There are some great examples that don’t require too much re-working to integrate into custom scripts.

I haven’t tried eclipse-based grinder install, I choose to install it and Jython manually, but I’ve no complaints about the integration — only that the errors and stack traces are somewhat misleading, only because they’re called through grinder.

I consistently have to shell-out to run the scripts manually when there’s a problem – the stack traces I see in eclipse are not useful in most cases.

Suvendu – You’ll have to provide a little more information about what you’ve tried and where you are having problems

I am having issues getting data files to work in my grinder script(s).

If I run the script as record, it works no problem. but I recorded a single user login to my webapp. Basically, I want to use a list of username,pass pairs from a data file.

I also have a list of ’sites under test’ that I need to feed into the test script(s) so they itterate over the sites.

My final goal is to be able to configure X number of users concurrently active across Y sites concurrently…

can anyone point me to an example of how to use a datafile to feed a test script?

also, love to see that code to setup a ramp-up / ramp-down rate.

Kyle- the next steps are to create/modify your scripts and run them. See this page for more about running scripts using grinderstone: http://code.google.com/p/grinderstone/wiki/Usage

You can also run them using the Grinder console, if you prefer, but during script development, I find it much easier to use the combination of Eclispe & grinderstone

I have a question actually – this looks like it’d be right up our alley, as I’m looking to set the Grinder up at our site. I’m having difficulty with your instructions however – this is my first foray in to Jython, Python, and Eclipse.

When you say “Here is a very basic Grinder script”, I assume I’m making that in Eclipse – and I named it “script.py” just by accident, but that seems to be right… what are the next steps here?
