when i was run jmeter webdriver script multiple browser is open and this condition not get accurate load testing report so how i get proper load testing report without open Browser?
As per WebDriver Tutorial
Note: It is NOT the intention of this project to replace the HTTP Samplers included in JMeter. Rather it is meant to compliment them by measuring the end user load time.
So you should not be using WebDriver Samplers to create the main load as browsers are very resource intensive and most probably you won't be able to kick off more than 5-10 browsers on a single machine.
If your requirement is to conduct the load testing using 100 real browsers - you will have to go for Distributed Testing
If you want to use existing Selenium tests as a basis for a protocol-based load test you should record them using JMeter's HTTP(S) Test Script Recorder. You can set the proxy for your WebDriver tests as follows:
So we have an option to run webdriver smaplers without opening the browsers if you are using chrome browser for this. You add jp#gc - Chrome Driver Config config element and there are 3 tabs in that those are "proxy", "chrome" and "Experimental". So you click on "chrome" tab and check the check box of Use Chrome headless mode. See the screenshot below.
In reality if you want to run webdriver samplers for more than 100 browser then I would suggest you that u use distributed test. Because browsers are resource consuming if you run around 4 browsers then your system starts hanging. so you cannot run 100 browsers. So go with Distributed testing in jmeter.

Detailed steps please, tried to use both HTMLUnit Driver Config and PhantomJs config, but no luck
How to run headless browser in jmeter for WebDriver Samplers, detailed steps please, tried to use both HTMLUnit Driver Config and PhantomJs config, but no luck. My requirement is I need to convert selenium script into jmeter script, I have created Webdriver script in jmeter, I need to run it with 100 users, as I donot want to launch 100 instances of browser, I want to run it as headless browser, directly creating jmeter load script is not an option as request is using a dynamic valuse which is not available in server response.
You will launch 100 instances of browser in any case, no matter whether browser is headless or not and most probably your JMeter system will not be able to handle that many browser instances and you will have to go for distributed testing
Your "no luck" statement doesn't make sense as information is not sufficient to come up with solution.
For HTMLUnit it is enough to add HtmlUnit Driver Config and WebDriver Sampler itself
For PhantomJS Driver Config you need to download PhantomJS binary and specify location under PhantomJS -> Path to PhantomJS executable input. Of course add WebDriver Sampler with your code
In both cases you will need to have Selenium client libraries somewhere in JMeter Classpath so make sure to install WebDriver Sampler using JMeter Plugins Manager - it will automatically take care of the dependencies.
If JMeter doesn't work as expected first of all check jmeter.log file for any suspicious entries - in 99% of cases it contains enough information to get to the bottom of the issue.
Also be aware that dynamic value is not a showstopper, in the absolute majority of cases it is somewhere in response (either in body, or in URL or in cookies, or in headers), in remaining cases it can be calculated or generated.
I'm trying to understand the performance impacts of things like WebDriver.findBy(...). For example if I was using Selenium to drive a local Chrome instance:
WebElement betty = webDriver.findBy(By.id("betty"));
Does the Selenium library
a) have the DOM within the JVM to evaluate?
b) go to the local Chrome driver binary to evaluate?
c) go to the browser instance to evaluate?
And does the answer change for a Grid situation?
I found a nice technical guide that explains this.
The browser driver uses an HTTP SERVER which waits continuously for
new Selenium commands.
It has the following purposes:
read HTTP requests coming from the client (client = computer that executes the test automation scripts)
determines the series of steps needed for implementing the Selenium command
sends the implementation steps to the browser
gets the execution status from the browser
send the execution status back to the client
For each Selenium command of the automation script, a http request with a specific path is created.
When the automation script is executed, the first http request generates a new session that is specific to the browser where the automation scripts run.
The session id will be used for the http requests that correspond to all other
Selenium commands from the automation script.
SmartMeter saves huge time using the built in test recorder but it has a limitation where user has to use built in chromium browser.
May I know How to record business transaction using alternate browser (IE, Firefox) ?
Unfortunately, you cannot use Chromium plugin with a different browser. It is dependent on Chrome API. But you can always fallback to JMeter way. The HTTP(S) Test script recorder is still available in SmartMeter. There is also Smart Proxy Recorder, which extends the capabilities of HTTP(S) Test script recorder, but it still based on recording via proxy.
I would like to record the network requests of a Selenium test. Rather than using jmeter GUI, I would like to automate this process in a script. The idea would be to run a selenium test and record it simultaneously. Is there a built in way to do this?
GUI Jmeter is ideally for development of scripts, which are then run headless to get true performance figures.
You can develop selenium webdriver tests as junit tests, which integrate to JMeter very easily.
Running a recorded Selenium IDE test would not be so straightforward, better to export it as Java Webdriver.
Make sure you follow junit naming conventions and annotations (depending which version you use). Write the test class, including junit 'test' methods, then create a jmeter test plan with a junit sampler, and configure the junit sampler to run your test method[s].
maven and plugins can be used to make it all run seamlessly in headless mode on any host.
Once you have developed one of these, it will be easy to review the jmx test script and automate the process of creating more jmeter tests, if that is what you meant by automating the process.
Start JMeter's Proxy Server
Configure your Selenium script to use JMeter as a proxy. See Using a Proxy guide for configuration details for each driver
Run Selenium test - all requests should be recorded by JMeter.
Add the next test elements to JMeter test plan:
HTTP Cookie Manager - to represent browser cookies
HTTP Cache Manager - to represent browser cache
follow recommendations from How to make JMeter behave more like a real browser to properly configure embedded resources retrieval, user agent, request defaults, etc.
Configure Thread Group parameters according to your load scenario.
Replay the test.
I expect that you will need to apply some correlation, but it may be not required.
We have are planning to design a system where we are planning to invoke the Selenium test that is present in a remote machine with url for testing. The selenium program should open 3 browsers for example IE, FF and Chrome and open the page and take a screenshot of it. Later These screenshots should be sent from this machine to the java application.
Is it possible to achieve this functionality ? If so could you please guide me on how to do this ?
Yes, you need to start a Selenium Grid/Node server on the remote machine that is configured to run all 3 browser types. That configuration isn't easy but it involves launching the grid from a .json config file. Then, your local program needs to just run the 3 tests either in 3 simultaneous threads, or one at a time using typical Selenium code.
Each test needs to define a Selenium Augmenter to get screenshots. There are lots of examples on Google.
