How can I do client side performance testing for Svelte applications?
Is there any similar kind in JMeter / WebLoad like true client protocol as in Load runner to test the Svelte applications?
TruClient protocol is just a real browser (maybe headless) so it is not a "protocol".
In order to test client-side performance you need a real browser -
The most popular browser automation tool is Selenium
JMeter can be integrated with Selenium using WebDriver Sampler
WebDriver Sampler can be installed using JMeter Plugins Manager

I want to load test a web application server which communicates through gRPC (which uses HTTP/2 for transport) with the clients.
It seems that Apache JMeter extended by the plugin JMeter gRPC Plugin and JMeter gRPC Request sampler would be perfect for this.
Among other things JMeter provides a Test Script Recorder which helps quickly generate scenarios by acting as a HTTP proxy between the client and the server.
Question 1: Is it possible to use the JMeter Recorder for recording the communication through the gRPC protocol?
Question 2: Is it possible to use the JMeter Recorder for recording the communication through the underlying HTTP/2 protocol?
I have tried already the JMeter Recorder to record the gRPC communication without success :-( Maybe caused by wrong configuration of the recorder?
No, at least not with JMeter 5.5
No, as of JMeter 5.5 the HTTP(S) Test Script Recorder doesn't support HTTP/2. Neither it does support .proto files so even if you record the raw packets you won't be able to decode them into anything meaningful
So I would recommend using a sniffer tool like Wireshark for capturing the packets between client and the system under test and then replicating the same using JMeter's GRPC sampler.
The version of jmeter i'm using is 5.3
and the setting I'm using here is https://prnt.sc/zothxr for the web socket
I need to give load in the websocket using this jmeter & websocket
Looking into the plugin source code it appears that the session is not established so you might need to check your hostname/path/implementation and look at server and JMeter log files, it might be the case you didn't install the necessary dependencies or something like this.
Also the plugin you're using is kind of outdated so I would recommend switching to JMeter WebSocket Samplers by Peter Doornbosch, it can be installed via JMeter Plugins Manager and it has more features comparing to the version you're using.

I want to automate REST API using Jmeter. My requirement is trigger and validate the signals generated from the field.Messages from the field like "communication lost" need to check whether this message reached API or not.These messages are developed using "signalr".Can anyone tell me how can i get the messages from signalr in Jmeter.
As per SignalR main page:
ASP.NET SignalR is a new library for ASP.NET developers that makes developing real-time web functionality easy. SignalR allows bi-directional communication between server and client. Servers can now push content to connected clients instantly as it becomes available. SignalR supports Web Sockets, and falls back to other compatible techniques for older browsers.
So my expectation is that you can use WebSocket Sampler plugin in order to test this functionality. The plugin can be installed using JMeter Plugins Manager, check out WebSocket Testing With Apache JMeter article for comprehensive information on installation, configuration and usage of the plugin for WebSockets load testing.
Can we test mobile application either iOS/Android(Native/hybrid)App using Apache JMeter? If yes, what's the way?
You cannot test mobile application directly i.e. how long does it take to load, how responsive it is, etc. via JMeter. What you can do with JMeter is to simulate large number of mobile devices talking to your backend server to measure performance and also apply some client-side assertions to make sure that server's response is not malformed.
It is possible to record mobile application network activity via JMeter HTTP(S) Test Script Recorder as follows:
Add aforementioned HTTP(S) Test Script Recorder and a Recording Controller to Workbench
Make sure that host, running JMeter and mobile device are on the same network (i.e. use Wifi, not cellular data plan) and the host running JMeter is accessible (i.e. firewall software doesn't block port 8080)
Start JMeter's proxy
Configure device to use JMeter's proxy.
Launch your application and perform necessary actions
When you finished stop JMeter's proxy and copy recorded requests to Test Plan
Perform correlation and parametrization if needed
Configure Thread Group virtual users and ramp-up according to your load scenario.
Launch the tests
Analyze results

I have a desktop based(.exe) application used for trading of equities.
1.Developed in VB uses TCP/IP.
2.Uses a database server which is an another server which the exe sends requests on.
3.I want to get the entire response using jmeter for 50 users at a time.
I wanted to record the responses for the transactions.I have worked with web applications where we create Http proxy server and start it and the recording happenes from browser but in this case i cant use browser.
Please guide me how to record the responses in jmeter with .exe applications.
Thanks and Regards,
Kumar
JMeter HTTP(S) Test Script Recorder is capable of recording only HTTP or HTTPS traffic so if following conditions are met:
Your .exe application talks to server using HTTP
Your .exe application can be configured to use HTTP proxy or respects Windows global HTTP Proxy settings from registry (or configured in Internet Explorer)
the answer is "yes", you can use JMeter to record the traffic. See Load Testing Mobile Apps. But Made Easy. guide for details on how to do it.
If one of above conditions cannot be satisfied there are following options available:
If you still want to use JMeter there is a possibility to use a sniffer tool like Wireshark to capture requests and manually construct them using JMeter HTTP Request or TCP Sampler.
Consider switching to Grinder tool which offers TCP Proxy
Hope this helps.
