testing - Not able to run webdriver scripts from jmeter -

i trying execute webdriver script jmeter. have installed webdriver plugin. created firefox config element , web driver sampler.

added script under webdriver sampler -

wds.sampleresult.samplestart() wds.browser.get('http://google.com') wds.sampleresult.sampleend() 

but while executing, browser not opening.

i'm pretty sure have firefox version not supported underlying selenium libraries.

• webdriver sampler plugin 1.2.1 supports firefox 33
• webdriver sampler plugin 1.2.0 supports firefox 26

if need latest firefox other reason can have firefox 26 or 33 installed somewhere else. add following line system.properties file (lives under /bin folder of jmeter installation)

webdriver.firefox.bin=/path/to/your/firefox/directory
