WebSocket Servers are preferred for real-time connections while overcoming the limitations of HTTP.
You get reliability and two-way communications tobuild real-time applications.
However, before using it, you should test and troubleshoot it.
Let me highlight why testing WebSocket and the tools it’s possible for you to use is essential here.
Why Is WebSocket Testing Needed?
A WebSocket API creates and manages WebSocket connections to the server.
Thats why WebSocket testing is needed to identify potential issues with the connection and explore how to fix them.
Technically, a couple of things need to be verified when WebSocket testing.
If you might intercept the link and change the message, you will be able to know the problems.
Of course, all of this is possible with the help of testing tools.
With the right tool, you might thoroughly test WebSocket APIs and their functions before deploying them.
To highlight separately, let me briefly mention them.
Whether it is WebSocket or anything else, connections should always be secure.
And, when you test the connections, you know more about the implementations.
While you test for everything, the performance also matters.
you’re able to think about taking the initiative to improve your performance as per the test results.
It should help you in the long run if you’re free to fine-tune the server better.
You should always choose goodWebSocket serversto ensure the best reliability.
One of the most significant benefits of WebSocket API testing is to test the business logic.
This makes sure that the WebSocket does not accept invalid input.
If you do not have enough servers, the connection will close, affecting the performance.
Not to forget, it is tricky to collect response times during the testing phase for asynchronous calls.
Asynchronous calls refer to the situation where the server communication will depend on how/when the user interacts.
Here, lets mention some excellent WebSocket testing tools along with their key features for you to try.
Pie Socket
Pie Socket offers managed WebSocket, utilized by various brands.
Even if you do not use its services, you could use itsPieSocket WebSocket tester.
However, it might not fit all kinds of testing use cases.
Insomnia
Insomniaprovides a dev-friendly platform with automation and plugin support to test APIs faster.
Test WebSocket APIs efficiently to integrate them as soon as possible into your applications.
you’re free to get started for free with core tooling access and collaboration feature for one project.
You must opt for its paid plans for end-to-end encryption and more cloud project support.
Postman
Postmanis a popular API platform to help you build and test APIs.
you’ve got the option to do numerous things related to APIs ranging from documentation to test cases.
you’re free to create a new WebSocket request or open a Socket.IO request.
you’re able to also refer to itsdocumentationto know all about it.
Autobahn WebSocket
Autobahnis a fully open-source test suite to automate client/server implementations of the WebSocket protocol.
It includes the essentials, compliance checking, and performance/limit testing.
apic
apicis a free and open-source API testing solution.
It helps you with designing your APIs and testing the APIs.
you could also generate API documentation and test reports to share with anyone.
Furthermore, you get an API simulator feature to help you test/mimic the responses based on your API design.
PortSwigger
Remember that I mentioned improving the security side of things as part of testing benefits?
PortSwiggers Burp Suiteis focused on web security testing and supports WebSockets as part of its offering.
you’re free to test it on your local system or cloud using the same script.
you could design and debut WebSocket requests without any hassle.
Apidog is free to get started with limits to storage for all the essential functionalities.
These are not the usual testing tools to help developers withessentials, but only a part.
So you’re able to try it out.
WebSocket King
WebSocket Kingis somewhat similar to PieSockets web tool.
You have to enter the WebSocket URL and check the output for all sent/received messages.
It does not support Socket.IO connections.
So, you will be limited to the raw insecure connections.
Of course, the tool you require will vary on your use cases.
So, feel free to try what works best for you.
