JMeter使用WebSocket连接测试身份验证

Question

I have testing my application (this only back end) in Jmeter. I doing functional test in JMeter. Now I want to testing authorization. My authorization is following: open WebSocket connection and then send JSON.stringify as KeyService.

What I can testing in JMeter this? I think first added to ThreadGroup in Test Plan - WebSocket Open Connection and set Server name and port,. next WebSocket P{ing/Pong, next WebSocket Single Write Sample - and this in Request data I think written as sstring format Key so for example "1234566788" which is in json format. and next added WebSocket Single Read Sampler?

Is it correctly doing test? what else add? maybe I should add Json Extractor (or something other?) and in this written content json.stringify file ? how is it the best way to tested this in JMeter?

Answer 1

The best way to test something with JMeter in particular or load test anything in general is to put it under anticipated load and make sure that each JMeter thread (virtual user) performs exactly the same actions as real user (or application) would do .

In other words, well-behaved load test must represent system under test real-life usage as close as possible, better with 100% accuracy, otherwise such test will not make a lot of sense.

The general recommendation is recording the traffic between system under test and "consumer" - browser, application, other server using a sniffer tool like Wireshark and then re-create the same traffic using JMeter so requests would be exactly the same (apart from dynamic parameters which need to be correlated )

In your case if the test scenario is about logging in you might want to verify whether you're really got logged in after sending a corresponding request(s), you can use Response Assertion in order to check response code, message and/or body and conditionally fail the sampler if response contains the data it shouldn't (or does not contain the data it should)
