How to create automation test flow with JMeter? - api

Is it possible to create Automation test flow with Jmeter?
So that all the Jmeter tests run it self and then I just gets the result generated for it?
Also can we add different scenarios for an application in that automation?
It would be great if some one can share on how to start from scratch for JMeter Automation.
Thanks

I don't think it is possible to have "Jmeter tests run it self ".
JMeter tests can be invoked in multiple ways:
Command-line
Ant task
Maven plugin
All options provide results either in .jtl file format or in HTML
If you want to invoke the tests in unattended manner - you can either rely on your operating system tasks scheduling mechanisms like Windows Task Scheduler or cron or even use a continuous integration tool like Jenkins, all of them are capable of kicking off the arbitrary tasks depending on various criteria, produce reports, display trends, etc.

Reporting test result in order to create nightly metrics

I have a micro services system written in java and deployed using docker containers.
In order to run our nightly tests, a tester container is started, performs it's e2e tests upon the system and creates it's junit report.
I wish to generate a summarized report at the end of the tester's run, simply a list of failed tests, and send it to another server for long time storing and analyzing.
I suppose I could alter said Tester's Dockerfile, and add this functionality as a command which process the junit report and send it, but I wonder what should be the best practice, both for generating the report and sending it.
Thanks in advance,
Ariel

Can Karate-Gatling scripts be used to have distributed testing/clustering for performance testing

We are currently using Jmeter for API performance testing in distributed mode (1 master + 3 slaves) as need to generate 10k requests.
Now using Karate for API functional testing and could integrate with Gatling using Maven dependencies successfully. As documentation says I could inject users and duration in these scripts and run>generate report (tested for 10 users).
Kindly guide, having below queries:
Is it possible to make these Karate-Gatling scripts to run as we do in Jmeter distributed mode.
How many users can be injected using Karate-Gatling scripts in a single machine (AWS/GCP mini instance/VM).
I guess this might vary how fast the application responds/volume.
I have gone through Jmeter Vs Gatling and looks like Clustering/distributed mode is supported only in Gatling paid version.
As per Gatling Performance Testing Pros and Cons article:
If you don’t want to pay for Gatling FrontLine, but you need to take your load test a little bit further, it may not be so easy to distribute the load as it is with JMeter. Despite that, not all is lost, as Gatling actually provides a way to distribute the load with the free version of the tool.
The way of distributing load in Gatling can be found here, but the main idea of Gatling’s distribution is based on a bash script that takes care of executing the Gatling scripts located in the slaves machines, which then sends the logs generated by the simulation to the master machine, where the consolidated report will be built.
So you can kick off several Gatling instances on several hosts and use the Bash script provided in order to run your test simultaneously on different machines. You might also want to use ssh-copy-id command to avoid entering the password for each machine

Migrating from LoadRunner/The Grinder to JMeter: Where are the Scripts?

I've done load tests for users building scripts in LoadRunner or The Grinder, and now I'm trying out JMeter and it all feels incredibly clunky. Where are the scripts? Does everything have to be done through the UI? Is JMeter able to do complex scripting?
JMeter has good user friendly GUI. We create scripts in JMeter using the UI. JMeter saves the script in XML format with .JMX extension. Script creation is NOT very difficult as you say.
Check this site to get an idea.
Complex scripting can be done in JMeter using logic controllers.
Also JMeter
Is Free & Open source
Is Light weight & easy to install
supports any platform
Supports many protocols - HTTP/HTTPS, FTP, SOAP, LDAP, JDBC, JMS, SMTP, POP etc
Supports external plugins
Can be extended with Beanshell scripts, Groovy, Javascript, Java.
I have tried out Jmeter briefly but I think to it's for you to try it out yourself, there are a number of Jmeter tutorials on the Jmeter site itself as well as on youtube which should prove useful.
Below are some links:
http://jmeter.apache.org/usermanual/intro.html
https://www.youtube.com/watch?v=cv7KqxaLZd8
Hope these links help you in getting a better understanding of Jmeter.
What do you call "scripts"?
JMeter is designed so anyone could create tests using UI only. JMeter's Logic Controllers, Pre/Post-Processors, Assertions, etc. are quite enough to build a load test of any complexity.
If you feel yourself too creative and you're limited by JMeter Test Elements you're welcome to extend it using
Code-enabled test elements like BSF, Beanshell, JSR-223 Pre/PostProcessors, Samplers, Timers and Assertions
Developing custom functions
Developing custom implementation of Java Request Sampler
Developing custom implementation of your own Sampler or Function
Finally it is possible to either run existing or create new tests using JMeter API

Jmeter recording in NON GUI mode for Selenium testing

I would like to record the network requests of a Selenium test. Rather than using jmeter GUI, I would like to automate this process in a script. The idea would be to run a selenium test and record it simultaneously. Is there a built in way to do this?
GUI Jmeter is ideally for development of scripts, which are then run headless to get true performance figures.
You can develop selenium webdriver tests as junit tests, which integrate to JMeter very easily.
Running a recorded Selenium IDE test would not be so straightforward, better to export it as Java Webdriver.
Make sure you follow junit naming conventions and annotations (depending which version you use). Write the test class, including junit 'test' methods, then create a jmeter test plan with a junit sampler, and configure the junit sampler to run your test method[s].
maven and plugins can be used to make it all run seamlessly in headless mode on any host.
Once you have developed one of these, it will be easy to review the jmx test script and automate the process of creating more jmeter tests, if that is what you meant by automating the process.
Start JMeter's Proxy Server
Configure your Selenium script to use JMeter as a proxy. See Using a Proxy guide for configuration details for each driver
Run Selenium test - all requests should be recorded by JMeter.
Add the next test elements to JMeter test plan:
HTTP Cookie Manager - to represent browser cookies
HTTP Cache Manager - to represent browser cache
follow recommendations from How to make JMeter behave more like a real browser to properly configure embedded resources retrieval, user agent, request defaults, etc.
Configure Thread Group parameters according to your load scenario.
Replay the test.
I expect that you will need to apply some correlation, but it may be not required.

Selenium And/Or TestSwarm?

I am new to testing, when doing some research these last few days i found 2 tools that enable testing a web application, here is what i understand so far:
Selenium provides a way to manipulate the browser, so in other terms it enables simulating user interaction on a webPage, we can write tests using PhpUnit-Selenium extension for example and it will make it possible to test our application as a real user would, after that those tests need to run on different browsers...
For TestSwarm i need to write my tests using tools such as (Qunit, Jasmine...) that are mainly focused on unit testing (not user interaction ...) and use TestSwarm server to push those tests to available browsers to run them (i think this is automatic so no need for a user to manually run theses tests)
My conclusion is that Selenium and TestSwarm are somewhat complementary as Selenium enables testing user interaction overall, and TestSwarm simplifies testing javascript cross Browser.
Am i getting this right?
I think you are on the right track, here is an excerpt from https://github.com/jquery/testswarm/issues/258
Okay, so you're using WebDriver and your test suite is a set of instructions (in what language do you have it stored now?) for the browser to execute (go to page X, click button Y, etc.).
Those are not unit tests but integration tests. They require bindings with the browser and/or the ability to execute code on the target computer. They can't be executed from within the browser (in that if I visit the url of your test suite in my browser, nothing happens as the driver instructions need to be run from outside the browser or from a plugin).
TestSwarm is not designed for these kind of integration tests, but for unit tests. A very different method that simply can't be performed by TestSwarm. Also, you wouldn't need any of TestSwarm's features for this and you'd miss things you need instead (like actual browsers and the ability to control them and extract the results). Where those browsers come from there usually is something like TestSwarm close by.
I'd recommend looking into SauceLabs and Jenkins (either self-hosted or perhaps a cloud based solution like CloudBees).
