Launch a new browser at every thread group iteration(Web driver sampler)

[prabhanjan]

Hi,

    I am using Jmeter web driver sampler version: 1.3.0. 

I require Jmeter to launch a new web driver browser at each iteration of the thread group. Right now we have a check box 'Create a new browser at start of every iteration' in the experimental tab of  Driver config element. By checking it, I get a error :

jmeter.JMeter: Uncaught exception:  java.lang.NoClassDefFoundError: org/openqa/selenium/os/Kernel32

This occurs for all the browsers i tried. If i uncheck the above option, it works fine but my requirement is to launch a new browser at every iteration. Can anyone help?

Hi,

This might be a packaging issue. Could you please try following:

1. Open a page http://search.maven.org/#search%7Cga%7C1%7Cfc%3Aorg.openqa.selenium.os.Kernel32
2. Download JAR for 2.46.0
3. Put this jar into jmeter/lib directory
4. Try running your test again
5. Let us know the result

This will help us to resolve it.

Hello Andrey,

                    I tried your solution by downloading and replacing the 2.46 jar. I had the same Jar previously. But I still get the above error. Looks like a Bug... Can you please give a fix?

This error also took me 1 day for finding solution. Luckily, I found my answer. Hope it will help you guys:

The root cause because my JMeter missing some libraries used by org.openqa.selenium.os.Kernel32. I have to found and copy these libraries into JMeter/lib folder. Here they are:

- jna-4.2.1

- platform-3.5.1

We can find them from Maven Repository. Need understand why I missed them in JMeter libs and whether it's the good fix; but, my issue has been solved. 

I hope this will help you who also facing this error :)
