Extracting value from Json response of POST request in Jmeter using Json Extractor

Asked 2021-Jun-13 at 09:42

Post request Json Extractor Get request debug sampler error message I'm using Jmeter for stress testing of my application. Test plan that I'm building has a POST request which creates a user and the next PATCH request updates it. Basically I want to extract user_id from Json response received after POST request and add that id in the body of the next request. For that I use Json extractor in my POST request and when I check Debug Sampler the value is successfully stored. But when I try to use extracted user_id in any subsequent requests of the same thread it is not recognized. However when I tried to extract user_id of already created user with GET request then this user_id is normally recognized by other requests. I'm not sure whether Json extractor is not normally used with POST requests or I'm doing something wrong.

It's impossible to provide an answer without seeing the screenshot of your Test Plan or even better Schematic View (the option is available under "Tools" main menu entry since JMeter 5.1)

Given you're able to see the extracted value in the debug sampler I can think of 2 possible options:

Your syntax of referring the user_id variable is wrong, in JMeter the Variables are accessed like ${user_id}
Placement of your JSON Extractor is wrong, i.e. instead of putting it as a child of a specific sampler you have it at the same level as all Samplers therefore it's getting applied to the Debug Sampler as well and the extracted value gets overwritten. See Scoping Rules user manual section for more information

QUESTION

Control the Pandoc word document output size / test image sizes

Asked 2021-Jun-12 at 07:41

My client wants to convert markdown text to word and we'll be using Pandoc. However, we want to control malicious submissions (e.g., a Markdown doc with 1000 externally hosted images each being 10 MB) that can stress/break the server when attempting to produce the output.

options are to regex the image patterns in the Markdown and test their size (or even limit the number) or even disallow external images entirely, but I wonder if there's a way to abort Pandoc if the produced docx exceeds a certain size?

Or is there a simple way to get the images and test their size?

...

ANSWER

Answered 2021-Jun-12 at 07:41

Pandoc normally fetches the images while writing the output file, but you can take control of that by using a Lua filter to fetch the images yourself. This allows to stop fetching as soon as the combined size of the images becomes too large.

QUESTION

What's the correct way to code split (lazy-load) an external library into a SvelteKit project

Asked 2021-Jun-06 at 18:37

tldr;

I'm getting the following warning when building a SvelteKit project with @sveltejs/adapter-static, lazy-loading Firebase JS SDK 9.0.0-beta.2:

[vite-plugin-svelte] The following packages did not export their package.json file so we could not check the "svelte" field. If you had difficulties importing svelte components from a package, then please contact the author and ask them to export the package.json file. -firebase

Everything seems to work in real life (i.e. on the client with initially static routes that later make calls to the Firebase API.) Do I need to stress about this warning? Note -- I don't think I'm ever "polluting" the static routes with direct Firebase imports, but I may be doing it all wrong. Please see below for my methodology.

More Info

firebase: "9.0.0-beta.2"
@sveltejs/adapter-static: "^1.0.0-next.13",
@sveltejs/kit: "next",

I'm lazily importing Firebase 9 (beta) into a SvelteKit project. I expose async getters for the various Firebase things like this...

ANSWER

Answered 2021-Jun-06 at 18:37

The warning basically says that if the firebase package exports any svelte components (which it doesn't), the svelte compiler won't pick it up and won't be able to optimize it. I have seen the warning too and I don't think there is anything to worry about.

Stress test of many users accounts with JMeter

Asked 2021-Jun-06 at 17:10

I want to perform a stress test on different cases for my web application with JMeter. I have a small network and each PC has a large number of user accounts.
I have configured JMeter to produce the same network footprint as the browser and I can record the requests generated by browser using JMeter's HTTP(S) Test Script Recorder. What is the next step? Do I have to create test plan for each case with Samplers and Listeners (Load TEsting) or just increase the number of users and check for errors at the Graph Result?

...

ANSWER

Answered 2021-Jun-06 at 07:05

You need to simulate real-life activity of each real user, if all of them are doing the same actions - it's sufficient to implement these actions. If different users are doing different actions - it makes sense to move these actions into different Thread Groups

Stress Test assumes finding the limits of your application so I would suggest the following approach:

Start with 1 user
Gradually increase the load at the same time looking into Response Times Over Time and Transactions per Second charts
Up to certain load response time will remain the same and throughput will be increasing at the same factor as the number of users does, when response time will start growing and transactions per second will decrease it will indicate that you reached the saturation point and that would be the maximum of users which your system can support.

Try to avoid using listeners as they don't add any value, just consume resources, you should be running your test in non-GUI mode and when the test finishes either use listeners to open and analyze .jtl results file or generate HTML reporting dashboard

Shiny create new variable based on Numeric Input and plot SOLVED BY MYSELF

Asked 2021-Jun-02 at 15:35

UPDATE: I've found a mistake - I used plotOutput instead of plotlyOutput. All is fine now.

I want to build a Shiny dashboard that does something like that:

takes a dataset with a numeric variable value
uses Numeric Input widget to obtain a numeric value
creates new variable value2=value*number provided in the Numeric Input box
plots a bar chart

The sample code is below. It correctly places the Numeric Input box, but the chart does not appear (the box where the chart is supposed to be is completely empty). Why?

You're trying to send the search value in the AJAX as JSON, but your PHP is not set up to read JSON. (And it makes no sense to use JSON anyway, just to send a single value).

Just send the form data in form-url-encoded format, as it would be if you submitted the form without AJAX. jQuery can help you with this - e.g.

How do you look through arrays more efficiently? Javascript

Asked 2021-May-27 at 16:01

I've been doing a lot of the practise tests on codility and though all my solutions work, they always have hidden stress tests which include massive arrays, the following code for example needs to take array A and find the lowest positive number missing from the sequence.

e.g: given A = [1, 3, 6, 4, 1, 2], the function should return 5. 5 is the value of i which increments in the loop. Function returns whenever index i is not found in array.

It works correctly but codility tested it with a 1-100,000 array and it timed out at the 6 second limit. most of my codes on the practise tests tend to fail for the same reason. Any help greatly appreciated.

...

ANSWER

Answered 2021-May-27 at 11:06

Your code loops through every item in the array for every item in the array. This gives a worst-case runtime of O(n^2). You can get a much better result if you sort the array, and then iterate through it looking for any missing numbers.
