How to test webhooks with jmeter? - jmeter

I'm new with JMeter and I get a task on how to get the callback from the system.
I already using a parallel controller but not really understand how to use it.
I have 1 HTTP Requests so when I running with JMeter, status in response data is pending
I expected to get status is a success or failure status from callback after getting pending status
That I do with jmeter

No, JMeter isn't the tool for testing webhooks or responding to postback calls
You can check other solutions as testing webhooks https://webhook.site/
Or mocking API as https://beeceptor.com/

JMeter & socket.io - I can see the message I want, but the socket plugin is not showing what I expect

Here is the socket message I see in the browser debugger console:
More illustrative, perhaps:
I call an API operation that triggers this message over a socket.
What I Tried
To preclude inaccuracies, I started 2 instances of JMeter.
REST API call.
Revised version of the GitHub JMeter example of sockets.io, in which I just call a WebSocket Sampler repeatedly on wss://events.dev.myserver.com:443/socket.io/?EIO=4&transport=websocket.
I kicked off (2).
While that was running, I kicked off (1).
Expected
Eventually, (1) should show me a sampler in the View Results Tree with the message in the screenshot ("42" - GAME_STARTED)
Actual
The only messages I see look like this:
This is really all I want to do: run the appropriate sampler, a sufficient time after making the API call, to get the message.
Update
We succeeded in finding the message using python-socketio:
sio.connect("https://events.dev.server.com", transports='websocket',
headers={'Sec-WebSocket-Extensions: permessage-deflate', 'Sec-Fetch-Dest: websocket',
'Sec-Fetch-Mode: websocket',
'Cookie: ABCSESSIONDEV=NTI3MzkwNWUtMTJmNS00Y2U0LTk1NGUtMjQ2Mzk5OTYxZWE0'})
And here is the output:
Received packet MESSAGE data 2["message","{\"locationId\":110,\"name\":\"GAME_STARTED\",\"payload\":{\"id\":146724,\"boxId\":2002,\"userId\":419,\"createdAt\":\"2022-03-02T14:35:31\",\"lastModifiedAt\":\"2022-03-02T14:35:36.752\",\"completedAt\":\"2022-03-02T14:35:36.621\",\"activationMethod\":\"TAG\",\"nfcTagId\":\"xxxxxx\",\"gameCount\":1,\"app\":false}}"]
I would like to use the websocket plugin to do this in JMeter now.
tried adding Cookie to WebSocket call - only sids, no messages.
tried adding Cookie to an HTTPS request (like the above code) - 400, bad request.
Take a look at other fields of the HTTP Request, in particular HTTP Headers, most probably your JMeter request is missing some essential information.
My expectation is that in order to "start the game" (whatever it means) you need to open the page in the browser, authorize somehow, follow the steps of the protocol upgrade mechanism, etc. to wit exactly mimic what real browser does, all the request sequence which is prior to starting the game.
You might need to correlate dynamic parameters, add HTTP Header Manager, add HTTP Cookie Manager, etc.

HTTP request on JMeter test failure

In my JMeter test, if there is any error, I want to trigger HTTP request to post a message on my system for further attention. What can I do here? Mail visualiser works fine to report errors over email. I want to do the same but over HTTP request. I am using jmeter 3.2.
You can do something like:
Add If Controller after the HTTP Request sampler and put the following code into "Condition" area:
`!${JMeterThread.last_sample_ok}`
Add SMTP Sampler as a child of the If Controller and configure your email server details, credentials, message, etc. there - see Load Testing Your Email Server: How to Send and Receive E-mails with JMeter article for more details.
JMeterThread.last_sample_ok is a pre-defined JMeter Variable holding the result of previous sampler execution, it is true if previous sampler is successful and false otherwise. Due to the If Controller the SMTP Request sampler will only be executed in case of HTTP Request sampler failure which seems to be something you're looking for.

Need to send the web service request contentiously till get response using JMeter

My requirement is as follows:
I will be copying one test data file to one location. [My application will pick file, process it and will respond using web service]
So when I login to my application and go to that page, every 5 seconds web service request would be sent.
Above two, i can handle using JMeter. Now next is
Need to send the web service request contentiously [maybe each request in 5 seconds] till get response using JMeter
So how can I do this?
Please help. Thanks!
Something like:
While Controller with condition depending on the response
HTTP Request Sampler
Constant Timer to sleep for 5 seconds
Maybe a Post-Processor to set the While Controller's condition
See Using the While Controller in JMeter article for more details on implementing while loops in JMeter tests.

Jmeter - mark the test as failed based on response data

I have written a jmeter test script which automates booking in of cases by sends http post requests to our web application.
At the moment as long as you get a response back from the server it's successfull.
Is there a way it can pass the test only when the response doesn't contain the message error has occured and contains a booking reference
You can use Response Assertion
To test that response does not contain Error message check the "Not":
See also:
https://www.redline13.com/blog/2016/01/what-are-my-options-for-using-assertions-in-jmeter/
You can use Assertions for this.
With this u can lookup the response body, the response code...
Look at this tutorial: https://www.blazemeter.com/blog/how-use-jmeter-assertions-3-easy-steps
You can stop the test if one assertion fails in the thread group (I think).

JMeter 0% error but no data

I just test my application that insert some data to database on other machine. Until the last scenario of test, jmeter says 0% error. But when I check my database, no data there. Where should I check this thing??
You need to use response assertions in order to test the correctness of response. Add response assertions and run the tests. At times the response code may be 200 ok but the action may not have been performed. In such cases you use response assertions.
Also verify response of your request to check the correctness of your script.
You should be looking at request and reesponse details in the View Results Tree listener. Also if your test relies on/uses JMeter Variables or JMeter Properties - you should also consider Debug Sampler or Debug PostProcessor
JMeter automatically treats 2xx and 3xx HTTP Response Codes successful, but it doesn't check integrity of response so it is totally up to you. See How to debug your Apache JMeter script article for more detailed tips.
