Openapi-generator to create jmeter script - jmeter

I'm using an openapi-generator-cli(5.4.0 v) jar to create a JMeter script. However, it is throwing errors for all the API's in swagger JSON.
I tried generating the script for pet store JSON. It's working.
Please let me know what could be the issue.

I don't think it's possible to use "openapi-generator-cli(5.4.0 v) jar to create a JMeter script", if you want to generate a JMeter test plan from the OpenAPI definition I would suggest doing this like:
Obtain Taurus tool
Use swagger2yaml tool to generate Taurus YAML file from the API specification
Run Taurus as bzt yaml-from-step-2.yml -gui - it will open JMeter with the generated test plan
Save the test plan as JMeter .jmx file

Is it possible to get Blazemeter like report in JMeter?

I want to generate a report in JMeter exactly like Blazemeter. Do we have any listener in JMeter or any plugin. I did search on google but didn't find the exact solution. If anyone has idea then please suggest.
Take a look at Taurus tool, it provides possibilities to:
Run existing .jmx script
Get online interactive report in your browser
Load existing .jtl results file to BlazeMeter
There is The Complete Taurus Course in the BlazeMeter University.
Alternative option would be using Backend Listener to store your test results in InfluxDB and visualize it using Grafana. There are several existing JMeter dashboards, you might find one of them covering your needs or use it as a basis for your customizations.

In Taurus, How to set "Clear cookies each iteration" to true?

I am trying to clear cookies after each iteration in Taurus yaml.
I tried the solution from below thread but it didn't work:
[Google Group] https://groups.google.com/g/codename-taurus/c/wa4xIbxkUYI?pli=1
Above thread says:
For reference I did it like this:
modifications:
set-prop:
"Cookies>CookieManager.clearEachIteration": "true"
I have tried the same but didn't work.
Using JMeter I can clear the cookies but need the same behavior for Taurus. Any help.
What do you mean "for Taurus"? Taurus just provides YAML configuration of some of JMeter test elements. The "solution" you're referring is for running existing .jmx script using Taurus
Taurus doesn't support 100% of JMeter functionality when it comes to building test plan from config, refer the documentation to see what is supported.
If you want to use some JMeter functionality which is not supported by Taurus the options are in:
Reach out to Taurus developers via the forum you're referencing and ask them to implement the functionality you need
Implement it yourself, Taurus is an open source project
Switch to the existing .jmx script execution
Switch to JMeter and stop using Taurus as a wrapper
Use JR223 Test Elements to perform the removing of cookies, i.e. you could add a JSR223 PreProcessor to the first sampler in the Thread Group and call sampler.getCookieManager().clear() function there where sampler stands for HTTPSamplerBase

JMeter altering values in .xls files using bean shell processor

I have a JMeter script where I should access a .xls file with multiple tabs and alter values .
The .xls file has values like , RASD1234,TWER1234,ZAST1234 . I should change the numeric value to unique values each iteration like RASD1235,TWER1235,ZAST1235 in all tabs . How can I achieve this in JMeter
Download tika-app.jar and put it into JMeter Classpath
Restart JMeter to pick the .jar up
Once you do this you will be able to use POI-HSSF API to edit the Excel file
Just one piece of advice: since JMeter 3.1 you should be using JSR223 Test Elements and Groovy language for scripting so consider doing this in Groovy (normal Java syntax will also work)

How to use Taurus to modify a jmeter script

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?

How to set parameters in .jmx file via Jenkins in Blazemeter test

What I need to do - create Jenkins job which runs Jmeter test in Blazemeter with some parameters such as a test URL. The parameters should be set in Jenkins before job starts.
What I have done:
Added Blazemter plugin for Jenkins.
Created an appropriate Jenkins job which will use the Blazemeter plugin for building.
Created Jmeter scenario and saved it in the .jmx format. I added a variable ${baseURL} with null value in the Jmeter's test plan which is used in the HTTP request as a Server Name or IP value.
Created a Jmeter test in Blazemeter and uploaded the jmx file. Saved the test.
Tried to run a job with the following parameters described in the session properties field in the Blazemeter plugin baseURL=${baseURL}. I set google.com as a property value in Jenkins.
Results - Blazemeter test has up and ran, it tested http:// however it had to http://google.com.
So the question is - What I did wrong or may be the Blazemeter plugin is not what i need or may be general approach is wrong.
The solution is the following: - use function __P or __property to get parameters into .jmx file. So i put ${__P(baseURL,)} function in the Server Name or IP statement and the Blazemeter successfully tested http://google.com.
