Whether node modules can be used inside jmeter?
For example can we import node modules inside webdriver sampler?
Node.js is a server-side scripting engine, the only "good" way to use it from JMeter is via OS Process Sampler
If you want to use some Node.js module in the browser driven by Selenium you might want to take a look at browserify which is capable of producing a single .js file which you can load and call its functions.
In general the only recommended scripting option in JMeter is using JSR223 Test Elements and Groovy language, I'm pretty sure that your requirement can be implemented in Groovy

I wanted to make a grpc calls through jmeter .Have done some searches but not getting the proper doc or site.
Would like to know if it is possible to make grpc calls through jmeter.
Also do we have some example doc/site for the same.
GRPC has Java API so you can generate client code (or reuse your application code if it's in Java) and implement the business use cases using JSR223 Samplers and Groovy language
Unfortunately the absolute maximum of information I can provide as the client code will be specific to your application so no one will be able to help unless you want to share the source code of your app which is highly unlikely to happen.
You may also take a look at jmeter-grpc-plugin (you will still have to write the code) and Client-side streaming RPC example
I'm looking to abstract the sequence of REST calls for complicated behaviors in my company's app into a series of classes that are instantiated as needed and the methods would effectively create the sequence of HTTP request calls. It's my hope that doing this would make the tests more compact and readable (as well as providing more reusable code). I would need to utilize the StandardJmeterEngine and export the test to JMX format after the HashTree test plan is created.
To cut on development time, I'm hoping to find a nice example of this; I'm sure someone's done it, but I've yet to stumble onto it.
If you are looking into the way of programmatic creation JMeter test take a look into the following sources:
JMeter API
How to Write a plugin for JMeter
Five Ways To Launch a JMeter Test without Using the JMeter GUI
If you are looking for an example project you can check out jmeter-from-code solution which demonstrates creating a JMeter Test Plan programmatically, storing it into a .jmx script file, running it and getting the .jtl results file.
I am just wondering is there any way or possible to generate JMeter script on the fly for the existing test automation script.
Basically the idea is to use the same Test automation script let's say Test automation script was created using selenium for the performance testing too using JMeter.
Any ideas or thoughts?

The solution is to record your Selenium test.
Start JMeter's HTTP(S) Test Script Recorder
Configure your Selenium scripts to use JMeter as a proxy
Start the test - JMeter will be recording.
This way you will get test "skeleton" however you will still need to handle dynamic parameters. To avoid this step you can try out an alternative recording solution, it is capable of exporting JMeter tests in "SmartJMX" mode with automated correlation applied. See How to Convert Selenium Scripts into the JMX article for more details.
The only way I am aware to achieve this is to record the selenium run and then save the jmeter script.
https://guide.blazemeter.com/hc/en-us/articles/206733979-Recording-a-user-session-with-the-proxy
Yes, it is.
You can run the JMeter stuff programmatically using JMeter API.
Using it, you can write your own test harness that creates the test items on the fly, then build the test plan out of them, and run it.
Or loads existing plan "template", access & alter the test elements in it, then, again run it.
Though that is kinda tricky part, so first ask yourself (then share with us here) what exactly do you need it for, and then try to consider the possibility to implement that using JMeter scripting components.
Basically, in your case, you can call the Selenium stuff in the JSR223/Beanshell components through Selenium API.
And moreover, there exist a plugin to do the things with Selenium stuff.
PS Although the very idea of using something all-purpose "to rule 'em all" usually doesn't pay off, 'cause the effort needed to maintain that "universality" often overcome the one smartly made for separate functional/load suites.
Here is the story:
we have several servers connected to wamp (crossbar.io)
I am creating load tests for part of this system and need a way to get info from wamp server to Jmeter.
So far I found only WS plugin for Jmeter, but it wont work with wamp.
Any bright ideas?
Clearly wamp is a whole new protocol and JMeter doesn't support it out-of-the-box. Thankfully you can extend JMeter quite easily. If there are java or java family language bindings for your protocol system, you can use beanshell sampler (relatively less performant) or groovy through JSR223 sampler (better performance)
If you feel like it, you can always write up your own Wamp sampler as well.
I am working on a project where the core application needs a harness to send messages which will process the message and feed to a portal web application. I am writing the automated testing for the portal application using cucumber/ruby/capybara.
I have never used Jmeter but through a colleague i just understand the basics of the Jmeter GUI tool. I have been asked me to use Jmeter as harness tool so that I can later extend the functionality to do performance testing as well. How can I do this ? How can i use Jmeter in my automated scripts using cucumber/ruby/selenium or capybara to do my testing ?
I dont want to use GUI as the whole test case should be automated end to end, I have to figure out a way to integrate Jmeter functionality to do test data set up and then run my browser test to check whether the data exists.
i hope my question is clear, ask me if you are not. Hoping to get a solution as i dont think it is a uncommon question.
Note: i have seen the ruby-jmeter gem, i think it does partly what i need but it is actually a DSL to use jmeter in ruby.the problem with that is I have to stick the syntax of gem and have to figure all the options in gem. I have also read a blog that this can be done using Jmeter recording proxy and running the browser tests at the proxy which I am not sure how to do that. here is the link where this is mentioned:

As per my understanding of the problem, please go through the below links
for recording the script using Jmeter:
http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf
for integrating selenium in Jmeter:
There are actually 2 ways of achieving this:
exporting all your selenium scripts as *.jar and copying it to /junit folder under /lib folder of Jmeter.
Use JUnit Sampler to execute your test cases:
http://intensetesting.wordpress.com/2013/09/25/integrating-jmeter-with-selenium-code/
use WebDeriver plugin for Jmeter and write your selenium test cases in Jmeter:
http://jmeter-plugins.org/wiki/WebDriverTutorial/
Also you can run Jmeter via command line.
