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.

I have an SLA from one of the clients from my organization, We have to test their application by following methods only,
Either we have to do an automation test script (using Selenium) and convert those test scripts to performance test scripts (to JMeter)
Nor we have to do a performance test script (using JMeter) and convert those test scripts to an automation test script (to Selenium)
Please let me know if there is any other simple method (Separate tool or Plugins) to convert any one of the test scripts to the other one.
Thanks in advance
Conversion from JMeter to Selenium is not possible (at least currently with JMeter 5.3 and Selenium 3)
Conversion from Selenium to JMeter is possible (up to certain extent), you need to:
Start JMeter's HTTP(S) Test Script Recorder
Configure Selenium to use JMeter as the proxy
Run your Selenium tests via JMeter proxy
JMeter will convert Selenium tests into HTTP Request samplers
You will need to perform correlation of the dynamic parameters and parameterization of at least credentials
I have Testng Selenium Framework for functional testing, i have a request to reuse that for JMeter performance testing. Since I am new to Jmeter please help me in solving the problem.
It is not possible.
In JMeter we create and XML based jmx file for execution.
The selenium functional test cannot be imported to JMeter
Configure Jmeter recording proxy and run the selenium script. All traffic from the browser will get recorded in jmeter. Then, do the correlation and parameterization. For authorization, you authorization module in jmeter.
Also, check the below link for another way:-
https://www.blazemeter.com/blog/how-convert-selenium-scripts-jmx-converter/
Please note, I am assuming that you require jmeter load testing and not GUI based execution from jmeter.
Hope this helps.
To execute the selenium related scripts what you need is to configure the webdriver sampler in jmeter and its browsers, after configuration a slight modification is required in the scripts to execute using jmeter.
For reference see the below given link

I would like to record a step through of a web application, and then replay this for testing. However it would be brilliant if this could be replayed say on a VM every so often to emulate a user to warm up a server.
JMeter, Katalon and Selenium have come up.
EDIT:
I have been playing with Katalon Studio and I'm very impressed with it in recording tests and replaying in a browser. This seems more about functional testing, ie do all the pages work. JMeter is about Load Testing. So different tools. However being able to export JMeter (JMX) files from Katalon would be fab, but I haven't heard it is possible.
JMeter can/is used also for functional testing and have selenium integration
Can JMeter and Selenium collaborate?
Yes. There are various situations where both tools can sync on the same testing application.
You can follow JMeter's recording steps to compare with katalon recording
You can do that with Katalon Studio.
Here's what I do to warm-up the servers:
I wrote a simple script (login with username and password, wait for web elements to load, logout),
It is repeated on various servers,
I put this Test Case in a Test Suite (because I can run test suites from command line),
Generate a console command,
Use windows scheduler to run the test suite daily early in the morning, before users start working.
I have been using selenium webdriver as my main method to do functional tests. So far its been working greate with our product.
I need to do some performance and/or load tests on the website, I was wondering if there is a tool that would incorporate my selenium tests or a tool which i can use with the recorded tests as the base.
Currently i am using selenium webdriver with C#
Any help is appreciated.
Given you have tests written in C# the most obvious way would be using Visual Studio Load Testing capabilities.
If you are looking for a free and open-source solution I would recommend going for Apache JMeter. JMeter has integration with Selenium via WebDriver Sampler plugin so you should be able to run your Selenium tests in multi-threaded manner. However you will need to convert your C# code into one of the WebDriver Sampler supported languages (default is JavaScript)
Remember that Selenium tests are very resource-intensive as real browsers consume a lot of CPU/RAM so the number of virtual users you will be able to mimic this way will be very limited. So recommended approach is creating main load on a HTTP protocol level and use one Selenium instance to check rendering speed while your application is under the load.
You can install WebDriver Sampler plugin using JMeter Plugins Manager.
Why do you need to run full browsers. HTTP layer tests are far simpler? You also should be looking at only a subset of business processes in performance which generate a preponderance of load.
I am presently working on a project for which selenium scripts are prepared and i want my jmeter proxy should record the steps executed by selenium browser. I tried running selenium and jmeter proxy server on same port but while doing that proxy server of jmeter refuse to start on same port. I read somewhere that this is possible but i am not getting the steps needs to follow.
You should do the same what you will do for simple test recording through Jmeter proxy:
setup Jmeter HTTP Proxy Server;
start configured Jmeter Proxy;
configure and enable proxy settings in your test browser (used by selenium) to use Jmeter Proxy.
Then run your selenium tests as usual, via configured test browser - HTTP Proxy Server will record execution.
To exclude all the steps performed in the "selenium-server" window try to add the following to 'URL Patterns to Exclude' in HTTP Proxy Server settings:
^/selenium-server/.*
Useful point here is to separate recorded execution into different Thread Groups - e.g. separate Thread Group in Jmeter for each recorded selenium testcase.
Step-by-step guideline you may found here.
To tell the truth such the "re-recording" may appear not very useful and effective: JMeter is not a browser, and does not interpret the JavaScript in downloaded pages.
As per Jmeter wiki:
JMeter does not process Javascript or applets embedded in HTML pages.
JMeter can download the relevant resources (some embedded resources
are downloaded automatically if the correct options are set), but it
does not process the HTML and execute any Javascript functions.
If the page uses Javascript to build up a URL or submit a form, you
can use the Proxy Recording facility to create the necessary sampler.
If this is not possible, then manual inspection of the code may be
needed to determine what the Javascript is doing.
So if you need Jmeter possibilities to implement load/performance-testing based on existent Selenium functional scripts better for you then use run Selenium scripts from Jmeter.
