Does testcafe RequestLogger intersect requests initiated from an iframe?
I try to mock all requests done for a page using RequestLogger but maybe I am facing the issue that requests initiated by the iframe are not mocked...
TestCafe intercepts requests from a page regardless of their source. If you have any issues with this functionality, please submit a bug report and add as much information as possible to the template.

I am able to get a screenshot in my JMeter test scripts using the Selenium chrome web driver. This works, but now I want to get screenshots following an authentication request. Is there a way to capture the screen as displayed in the HTTP request?
I don't think there is, theoretically you could try libraries like this one or this one from JSR223 Test Elements using Groovy language, but I don't think you will get what you want
The main reason is given at JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
HTTP Request sampler downloads only HTML, you won't get any images, scripts, styles, fonts, etc. so even if you try to use the aforementioned libraries you will get a "screenshot" which doesn't have anything in common with how does the page look in reality.
The Web Application having a list of features(Client-side actions) and These features are not captured, when I record through Jmeter/Blazemeter (NON-API (NON-HTTP) kinds of Stuff). These actions are handled through Javascript functions and .js file is not displayed in Network Tab.
So, I created the selenium scripts and integrated them with Jmeter. When I run the scripts it opens many browser instances(Headless) and performance stats get impacted.
I have to run this script with 5000 Threads. So Opening up so many browser instances is not an appropriate approach.
How to handle the client-side actions through JMeter?
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So you need to figure out what this "client JavaScript" code is doing and replicate this functionality by:
either using a suitable JMeter Plugin
or writing your own JMeter Plugin
or simulating this client-side JavaScript using JSR223 Test Elements and Groovy language
I am researching the differences between Selenium and JMeter and I stumbled across the following statement about Selenium:
Even though WebSocket might be encapsulated into a web session and
affect the browser, the user/Selenium will not realise it. So, we will
use JMeter for testing WebSockets.
which confuses me because even though Selenium can't detect that specific scenario, Selenium still uses a programming language like JAVA, hence you can still use Java to accomplish the same thing JMeter does in this case. Or am I missing something here?
I don't know what you're reading however I would recommend stopping referring this source as they don't really realize what they're talking about.
According to The WebSocket API documentation:
The WebSocket API is an advanced technology that makes it possible to open a two-way interactive communication session between the user's browser and a server. With this API, you can send messages to a server and receive event-driven responses without having to poll the server for a reply.
Selenium is browser automation framework therefore you get this WebSocket API support "for free". If you need to perform some custom use cases you can use JavascriptExecutor to call WebSocket object functions.
When it comes to JMeter:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
Therefore JMeter will not trigger any WebSocket-related events unless you use a plugin and manually open connection, send message, read response, etc.
I am beginner in Load testing and I am doing load testing using JMeter on a single page web application. The issue which I am facing right now that as you know in SPA there is a single URL and page contains multiple tabs, how I can switch between the tabs using JMeter. You can see my test plan in below image.
I Know I have little knowledge, any link or guidelines are welcome as there is a limited information on google regarding SPA.
Do not compare the load testing with automation testing. Jmeter can only trigger the request that your system is sending to server. The steps you need to do:
Open your URL in chrome/firefox
Inspect the page or tap f12 on keyboard.
Go to network tab
Now click on the tabs you have in your webpage
check if there is any request being passed to server when navigating through tabs.
If yes, replicate the same request by adding a HTTP Request in jmeter and provide the request headers and parameters same as that of the request being passed.
We're trying to validate if a URL fires upon loading a web page. Is there a way to do this programmatically using Selenium RC? The event does not appear within the page HTML or DOM.
Thanks.
Can you specify the URL as part of your test?
If so, then what about running a httpd server and checking if it gets a hit when your page loads?
The selenium.start("captureNetworkTraffic=true"); enables the 'capture' of all the HTTP requests/responses associated with the loading of the web page. Once formatted, these results can be reported easily.
