How to extract/share some common logic/sampler etc from many jmeter jmx files? - jmeter

If there are many jmeter scripts(jmx files) in a stress project for different cases run, how to maintain the common jmeter code which can be shared by each jmx?
For example, many jmx files have same thread group, http sampler, config elements (header manager, Authorization manager etc) ?
Any way to only edit once and apply for all jmx scripts? I couldn't find the related jmeter doc about this? wonder if jmeter jmx file supports any share code dynamic load/management?
Any suggestions are very appreciated!

My expectation is that you're looking for the Module Controller. In conjunction with Test Fragments you will be able to re-use sequences of the Test Elements either in current Test Plan or even in different .jmx scripts.
See Using JMeter Module Controller article for detailed information if needed

I think you mean the Include Controller. That way you can combine different jmx files to be run from one 'master' file. There are some things to keep in mind, but check the manual for that.

Organising JMeter API tests

I'm pretty new to performance testing.
I've got a bunch of endpoints to test and I wonder what is the best approach to do it.
I thought about grouping tests for endpoints in separate .jmx files, for example:
Suppose that there are 2 endpoints: A with simple GET method and B that can serve GET, PUT, POST and DELETE requests. In this scenario I would create 2 .jmx files.
Any helpful links to some tutorials appreciated :)
Normally people use Test Fragments for organizing large JMeter scripts.
Depending on whether you want to keep the requests in a single .jmx script or separate you can use:
Module Controller - for re-using requests in the same scripts (i.e. to avoid code duplication)
Include Controller - to "pull" external .jmx script into the current one

Jmeter not running for particular scenario

I am not able to run jmeter on this particular url- https://www.yatra.com/
It is working on other website like- https://www.makemytrip.com/
Different sites have different policies of how it can be accessed, that is why you can not do it.
You should practice Jmeter either on the application you are working on or else you can refer the below answer:

Jmeter - extend http test recorder

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

Looking for an Object Oriented JMeter 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.

JMeter - working with multiple tests

I am new with JMeter and I am trying to understand how to work with multiple tests plans.
Is it possible to define multiple tests plans in a single ".jmx" file, each with its own thread groups, etc. ? Or should I save each test plan in a separate ".jmx" file?
What is the correct and common usage?
It depends on your workflow and what you are trying to achieve, the most common use case assumes collaborative work of more than one people on the JMeter test scenario. In this case Test Fragments would be useful.
If you are trying to run several JMeter tests in parallel, the easiest option is using Taurus tool as a wrapper and just pass several .jmx tests to it either in command-line or through YAML configuration file.
I think you are looking for an approach for creating a modular JMeter test scripts.
There are many ways to achieve reusability/modularity in JMeter.
Test Fragment
Module Controller
Parameterized Controller
Include Controller

I am here because I'm asking the same thing than you #SomethingSomething
From my understanding and my point of view, to have multiple tests plans, you must create several .jmx file. For instance, if you need to test different servers or application.
If you need to test multiple scenario in a same application, so combining them into in a single .jmx file should be the better option (by using Fragments or Controllers).
