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:

use WebDeriver plugin for Jmeter and write your selenium test cases in Jmeter:

Also you can run Jmeter via command line.

I have a general question about Jmeter. I am using Jmeter and I want to create Continuous integration solution using Jmeter. The problem is that there are several QA, that each one of them have test plans according his development. the problem is that if using Jmeter all test plan need to run as one test plan, and for each of test plan to create report, and than manually over each report and check for failed scenarios. So all the handling is much harder than I thought, Jmeter is wonderful solution but how to use it with several test plans, and if I want it to run nightly? and in the mornng to get single report with all test plans that created? Can someone please advise if Jmeter can be solution for CI nightly? is it possible to merge all reports to single report?, each test plan is for unique development, and we will have multiple testplans over time
Did you have a look at those plugins:
https://github.com/jmeter-maven-plugin/jmeter-maven-plugin which allows you to fail a build based on presence of errors in load test results which you could mix with https://jmeter-plugins.org/wiki/AutoStop/
https://plugins.jenkins.io/performance
JMeter per se is just a load testing tool, you need a continuous integration server. If you don't have one in your company there are several free and open source solutions you can consider like:
Jenkins
Buildbot
Cruise Control
Check out Jenkins vs. Other Open Source Continuous Integration Servers article to learn more about aforementioned tools, see sample build dashboards and commands to kick off a JMeter test.
Is it possible to extend Jmeter http script test recorder?
Would like to edit recorded requests automatically instead of doing it manually.
JMeter is an open source software distributed under Apache License 2.0 so you can add whatever functionality you need.
JMeter source code is available via Git and SVN repositories and you can find the official manual on extending JMeter at How to Write a plugin for JMeter
If you'll create something very useful for others I believe it would be a good idea to contribute it back, send a message to Apache JMeter Developer for further instructions on how you can add your code to JMeter.
If your idea of "automatic editing" is about adding missing automated correlation and you need the functionality right away you can consider and alternative recording service instead of JMeter's built-in proxy, check out How to Cut Your JMeter Scripting Time by 80% guide for details.
Of course it is possible. Look at this one
How to resolve the below error in jmeter
1.) Request to open Google.com
2.)
P.S: I have just started learning jmeter.
Which is the best way to learn it, please advice.
The easiest way of creating a JMeter test is just recording it. JMeter comes with HTTP(S) Test Script Recorder which can be used for building a test plan skeleton via capturing browser requests, check out Apache JMeter proxy Step-by-step for more information.
I would recommend attending JMeter Academy, this way you will be able to quickly ramp-up in JMeter in particular and performance testing in general. Performance Testing Guidance for Web Applications book is also very useful
for performance testing greenhorns.
In regards to the possible error, I cannot see the details, just a blind shot: are you behind a corporate proxy/firewall? If yes, you will need to "tell" JMeter the details of this proxy so it could access the Internet (same applies to "recording" approach of tests creation), see Using JMeter behind a proxy chapter for the relevant JMeter configuration.
JMeter is not a browser
See first page of Jmeter
JMeter does not execute the Javascript found in HTML pages. Nor does
it render the HTML pages as a browser does
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.
