Running webdriver code in JMeter

With the improvements in technology more and more of the business logic gets executed on the client side and it’s not easy to get a clear picture of the perceivable performance by using pure JMeter tests only.
To extend these measurements JMeter-Webdriver plugin in JMeter can be handy to run WebDriver tests using actual browsers and to get client side execution statistics.

In the following section I will demonstrate how to configure and run a simple WebDriver test in JMeter.

First you have to download the plugin from the JMeter plugin page http://jmeter-plugins.org/downloads/all/ and then copy the library files into JMeter installation folder.

From now on when you start up JMeter you should have the extra Config Element and Sampler components visible on the tool list and they are ready to use


Add a thread group into a new Test Plan, then add a Firefox config and add a WebDriver sampler into the new thread group. You can also add a Listener to check the test results after a test run.

For this example the default configurations of the Firefox config is enough and we can directly select the WebDriver Sampler. On the sampler you can choose the script language, for case of simplicity we should stick to Javascript.

Copy the code from below into the script sections:

WDS.sampleResult.sampleStart()
WDS.browser.get('http://google.com')

if(WDS.browser.getTitle() != 'Google') {
    WDS.sampleResult.setSuccessful(false)
    WDS.sampleResult.setResponseMessage('Page title is not Google!')
}

WDS.sampleResult.sampleEnd()

In our example test case we will navigate to the main Google page and check its title.

Click the play button to start. If you followed the simple instructions the browser pops up and the test will pass.
