Is there a way to create a JMeter test plan without going through the GUI?
I.E. can you create a script with pure code?
In a way - yes. You can create the JMX file in a text editor, but it would require knowing what every component needs.
You're better off creating in GUI mode and modifying the JMX file manually as needed.
Yes it's possible to write a test plan just by writing JAVA code.
The key classes to look into are:
StandardJMeterEngine - the main class which configures the Test Plan and executes it
HashTree - a special collection which holds Test Plan elements
A minimum of JMeter Controllers necessary to run the test.

I can write and run JMeter without GUI. JMeter use JMX file, as you can here.
Not entirely sure why you would want to write a JMX in this way? ... But yes, entirely possible if you understand the structure of the document.
You could use any basic text editor to achieve this (notepad / notepad++ for example).
A JMX file is a saved JMeter project in XML format. ~ Ref
Depending on your needs you could the browser editor from the JMeter Plugins website.
jmeter-plugins.org/editor/
Or simply save a basic JMX as a template and spend loads of time learning the structure, syntax and namings etc.

I'm trying out taurus to run some existing jmeter scripts, setting various properties to local values.
I can use the -gui mode to load the modified script in the jmeter GUI and debug. However, I can't update this and replace the original file because Taurus has added two jtl data writers. I can suppress "Errors Writer" with e.g. -o execution.0.write-xml-jtl=none, but I can't see a way to suppress "KPI Writer". It's also possible further undesirable modifications have been made.
Is there a way to launch the GUI so that I can edit the original file, using the properties from the Taurus yaml file?
You cannot run the original jmeter scripts through bzt however it is possible to manipulate few properties of the newly generated jmx file through the yml file. Modified jmx is a copy of original script where two Listeners (errors and kpi) and variables from the yml.
It now depends on what exactly are you looking to change?
I add several components for debugging as Debug Sampler, View Results Tree and JSR223 Sampler that are useful in GUI mode, but I want it to be ignored when running load test,
Is there such option of executing Sampler/Listener only in GUI mode and not in command line/"load" mode?
I am not sure that this is the exact answer you are looking for but still let me try. We know that JMeter script is nothing but xml in disguise and structure look like this.
So for every Jmeter component, there is enable property which needs to be true so that it will get executed as part of JMeter Test plan. Now if we can change this some properties which can be passed as parameter then we can make them disable at the run time.
Change in jmx will be reflected like this...
If you run this script in Non GUI mode with additional property passed as parameter, we essentially achieve what we want.
jmeter -n -t .\ExcludeJMeterComponent.jmx -l result.CSV -e -o "Output" -DenabledDebugComponents=false
Issue with this approach is, if you load this script again in JMeter, these values, manually edited jmx going to go away/get override with your next save but if you are using any version control system to keep track of your jmx script [which you must be doing] it will be very easy to add this changes in the script again in no time.
I will post this with more details once my blog is set up.
Found a workaround, to send in CLI JMeter property as -JignoreFirstSampler
Add If Controller as a parent of samplers to exclude checking if property is defined
${__isPropDefined(ignoreFirstSampler)}
The __isPropDefined function returns true if property exists or false if not.
I am working on master-slave Jmeter configuration, my data set exist on each machine on a different path for (macOS, Windows).
I use a global data set to fetch data for multiple thread groups.
However, the variable/property can be different across platforms.
I also tried the JSR223 to check the, but still no luck. check out the below snapshot.
I am trying to make sure that once I ran my test from Master (Mac), it also run on Windows.
Any thoughts how to do that on multiple platform setup.
The best solution is placing your test data under the same path which will be relative to JMeter working directory, this way you will not have to change anything in your script.
If for some reason you cannot afford this you can add a JSR223 Sampler to your Test Plan and use the code like:
if (org.apache.commons.lang3.StringUtils.containsIgnoreCase(System.getProperty('os.name'), 'Windows')) {
vars.put('data-path', 'c:/windows/specific/path')
} else {
vars.put('data-path', '/macos/specific/path')
}
It will detect the operating system name in the runtime and you will be able to define an OS-specific paths using the above approach.
vars is a shorthand for JMeterVariables class instance, the above code defines ${data-path} JMeter Variable which you can use later on for specifying data files locations.

I have created some testcases in Jmeter.
Now I want to run them separately example smoke testcases only.
Is there any way in Jmeter so I can run my JMeter project for a particular group/collection/suite only.
Is Jmeter provide any annotation or containers mechanism from where I can achieve same.
I have written my cases in Jmeter in below assertions

Any workaround will be helpful and appreciated in advance
The right way to module your JMeter scripts is to save small script in different JMXs and combined them by calling each or inside a bigger JMX file which uses Include Controller to execute different JMX files
The include controller is designed to use an external JMX file. To use it, create a Test Fragment underneath the Test Plan and add any desired samplers, controllers etc. below it. Then save the Test Plan. The file is now ready to be included as part of other Test Plans.
Inside JMX you can also use Module Controller to reduce code duplication
The Module Controller provides a mechanism for substituting test plan fragments into the current test plan at run-time.
If you want to execute specific test I suggest send specific properties and check the property inside an If Controller .
for example call with property jmeter -JexcludeTest1=true ...
And add an If Controller before test 1:
"${__P(excludeTest1)}" == "true"
The easiest way is using Taurus tool as a wrapper for your JMeter script, it has Modifications for Existing Scripts feature where you can define which test elements you want to enable/disable during test execution.
scenarios:
modification_example:
script: tests/jmx/dummy.jmx
modifications:
disable: # Names of the tree elements to disable
- Thread Group 1
enable: # Names of the tree elements to enable
- Thread Group 2
See Navigating your First Steps Using Taurus to get started.
Another option is putting requests you would like to enable/disable on demand under If Controllers so you could set "run/not run" condition dynamically.
What I try to achieve is to get JMeter results in 2 formats, for the same test execution. CSV is the one I'm mostly interested in, unless there are failures - then I may need to use data which can be saved only to XML. I can't use XML for most occasions, due to misc reasons.
I was looking at jmeter.save.saveservice.output_format cfg entry, it doesn't seem to accept both as valid entry. I was also looking at JMeter code itself, it also clearly separates both options.
Did anyone invent a hack to get both JMeter outputs at the same time?
Solution for both standalone JMeter and jmeter-maven-plugin is welcome.
If you use JMeter Maven plugin, as per Five Ways To Launch a JMeter Test without Using the JMeter GUI guide the default output has to be XML.
If you need CSV output as well - just add Simple Data Writer listener. If you looking for CSV data to be in line with JMeter default CSV values configure it as follows:
