In order to get src folder you need to download JMeter source code separately, i.e.

This article got a bit boring, so I decided to throw in a silly question also.for Jmeter In the Jmeter case 100 VU will fetch 100 items in parallel (and if I am correct, the VUs will spend some time waiting also, instead of issuing requests). This means that in the k6 case, 100 VU may fetch 300 items in parallel. k6, on the other hand, will in the above case let each VU open three concurrent TCP connections, and so be able to fetch the three items in parallel, just like a web browser does. What Jmeter instead does here is synchronizing the VUs so they issue requests at exactly the same time (which to me seems less useful, to be honest - the total throughput will probably go down, given that some VUs have to wait for other VUs to complete requests). This means that thinking of a VU as "a user" becomes impossible a single human user will issue multiple requests concurrently, using their web browser, while a Jmeter VU only issues one request at a time. In the Jmeter case, we will still only have each single VU issue requests sequentially. The above "solutions" are not 100% comparable.

Use the http.batch() function to issue multiple requests in parallel: See Using the JMeter Synchronizing Timerfor more information on running specific requests at the same time in your JMeter test. Number of virtual users in Thread Groupis >= what is set in the Synchronizing Timer It is at the same level with both requests Just add a Synchronizing Timer to your test plan and make sure that JMeter provides Synchronizing Timer which allows grouping requests so they could be executed at exactly in the same moment. The question concerns being able to issue more than one request in parallel, like browsers do when fetching web pages and which puts a lot more stress on the server than having each virtual user just issue one request at a time.in Jmeter Even discounting this error checking though, the k6 code is shorter, and the k6 API is (IMO) simpler to use. The "k6/crypto" module is always available, so no need to check if the import worked or not, with k6. In both cases, we need to import the hashing functionality from an external module. Like always, with Jmeter you need to add something in the configuration (a JSR223 sampler) before you can start writing any code.

"I am thinking about how to test a servlet with two parameters: X and Y, using JMeter.X and Y are random numbers from 0 to 100.I am thinking of implement a nested loop which is something like": Refer extracted value as $ from "s3./path/to/logTransaction.js" 4.

Put the following code into the PostProcessor’s "Script” area: vars.put("response”, new String(data)).Add a Beanshell Postprocessor as a child of the request which returns the response you’re looking for.How to save an HTTP response in a variable. Let's look at the questions and responses in detail. How to extract first element from JSON array.How to reuse custom test code in different tests.How to save an HTTP response in a variable.They have been taken from SO threads so they may contain errors. In my developer-centric view user-scenario creation in k6 is waaay nicer than in Jmeter, of course :)Īnd, to be clear, the Jmeter answers have not been tested. So I have focused mainly on questions that make k6 look good, uh, err, I mean that I have focused on user scenario creation mainly. Obviously, some things that can be done with Jmeter cannot be done with k6, and vice versa. We thought: why not respond to some of the SO Jmeter questions, but write about how to do the same thing in k6? And better yet, why not compare how something is done in k6 with how it is done in Jmeter? Based on real Stackoverflow user questions! There are tons of questions and answers there about how to do things in Jmeter. It has seen a phenomenal reception (over 3,000 stars on Github already!) but there isn’t yet much about k6 on Stackoverflow (please do ask some questions there, if you have any!) Jmeter, on the other hand, is very well represented on SO. We recently released k6, the new load testing tool written in Go and scriptable in Javascript.
