I have an Web application which I have to measure the Performance from the Server response of that application while testing it manually in several machine.
How can I do it. Do we have any tool to measure the Server Response time of a Web Application while performing the manual testing on several machine.
Thanks,
Udhay S
Udhay,
JMETER provides you all necessary performance graphs from which you can get the server response. Its easy to use and you can increase the load to test the server response.
In JMETER you have a list of reports - Aggregate graph, Spline Visualizer graph and a summary report explaining the server response.
A stopwatch? Seriously, if you are running manual tests then the best, most accurate and the most purely subjective way to record how long it appears to take for a page to load is to use a stopwatch wired to the human brain. Until someone can invent a computer that can pass a Turing test this is as good as it gets.
If you feel like you need to automate things then automate the test first, and then think about automating recording response time.

I currently am creating a faster test harness for our team and will be recording a baseline from our prod sdk run and our staging sdk run. I am running the tests via jest and want to eventually fire the parsed requests and their query params to a datastore of sorts and have a nice UI around it for tracking.
I thought that Prometheus and Grafana would be able to provide that, but after getting a little POC for myself working yesterday it seems that this combo is more used for tracking application performance rather than request log handling/manipulation/tracking.
Is this the right tool to be using for what I am trying to achieve and if so might someone shed some light on where I might find some more reading aligned with what I am trying to do?
Prometheus does only one thing and it well. It collects metrics and store them. It is used for monitoring your infrastructure or applications to monitor performance, availability, error rates etc. You can write rules using PromQL expression to create alert based on conditions and send them to alert manager which can send it to Pager duty, slack, email or any ticketing system. Even though Prometheus comes with a UI for visualising the data it's better to use Grafana since it's pretty good with it and easy to analyse data.
If you are looking tools for distributed tracing you can check Jaeger
I would like to use Locust for UI performance testing. How to use Locust for UI performance testing? How can I get the loading time of the HTML elements(img, lists, etc..)?
Thanks
Locust isn't a browser and doesn't parse HTML. It just does plain HTTP requests and it will not load things like images based on the response.
If you need something like that, you would need to parse the HTML in the response and do the "dependent" requests in your test script.
Locust is not made for that (as said). There are some other fancy tools which will allow to do it for you e.g:
k6.io (https://k6.io/ - previously known as LoadImpact) - allows you to perform performance checks outside of your environment and report it back to the pipeline with results. Easy to configure and integrate, great when it comes to more "clever" testing scenarios such as stress tests, load tests etc.
sitespeed.io (https://www.sitespeed.io/) - my 2nd favorite, very fun to use and easy to configure tool to track FE performance and tests (e.g. done with Selenium)
Lighthouse Reports - might be also performed as a "pointer" to the most common issues and included as a PR comments e.g. or notifications during the process (there are many Github Actions or DevOps packages doing it)
I've also gathered some of my findings in my recent talk (slides below) and is converted into the series of blogs around these topics and first of them is already published:

Any idea how to test file streaming in Cucumber?
Note this is a Java microservice with a client and server architecture.
The client talks to the server on a designated port..I just dont know how to do this?
Most of the examples that I have seen are Browser Based Testing with Selenium.
I am writing Junit test cases for this and I wanted to know how this is to be done.
I am new to Behavior Driven Testing and I find this really exciting!
You have to imagine you are the client and that you are consuming the service. When you use the service what do you get back. If you are cukeing you need to think in business terms e.g. its about WHAT you are doing and WHY its important, not HOW its done. So WHAT is the point of this service, what value does it give.
If you just want to test that it works then I'd use a unit test tool instead.
How do I test the behavior of a java restful web service in case of multiple concurrent requests? Is there any 3rd party tool that can be leveraged?
The service accepts POST method. It expects a couple of parameters in it's request body and produces the response in the form of JSON.
The functionality of the service is to perform database read operations using the request body parameters and populate the fetched data in the JSON.
I would recommend one of the following:
SoapUI - superior tool for web service testing. Has limited load testing capabilities. However it does not scale (no clustered mode is available) and has quite poor reporting (all you get is average, min and max response times)
Apache JMeter - multiprotocol load testing tool, supports web services load testing as well. Has better load capabilities and ways to define the load patterns and can represent load test results via HTML Reporting Dashboard. Check out Testing SOAP/REST Web Services Using JMeter article to learn how to conduct a web service load test using JMeter.
You can try Gatling to generate some load.
It has nice documentation and easy QuickStart .
For advanced usage it requires some knowledge of Scala, but it also features GUI tool for simple scenarios recording, so you can run some scripts by postman or whatever browser tool you use for debugging, record it and make that scenario automated.
After running scenarios it generates nice reports using Graphite, so you can see response times and general stats.
Later you can also use Gatling for load and performance tests of your web service, it's convenient and fast as soon as you start playing with it. It can easily generate up to 5k requests per second from my old Mac, or hold up to 1k connections.
One of the bests tools to test web services is SOAPUI.
You can use it for what you want.

You can check this link to see how to use SOAPUI and concurrent tests.
I want to write one web application with node.js and MongoDB and I have got task to even test it. I would like to know if there are any tools like JMeter or anything else for load/stress testing of Node.js?
EDIT
My application is going to be information extraction kind of application and client expects extraction should not take more than 10 seconds for one document. Currently I have same application written in C# but its not scaling upto client's expectations. Then I came across this beautiful and fast Node.js. I think Node.js can help me alot.
Please enlighten !!!
Try nodeload: it's a collection of node.js modules for load testing HTTP services.
As a developer, you should be able to write load tests and get
informative reports without having to learn another framework. You
should be able to build by example and selectively use the parts of a
tool that fit your task. Being a library means that you can use as
much or as little of nodeload as makes sense, and you can create load
tests with the power of a full programming language. For example, if
you need to execute some function at a given rate, just use the
'nodeload/loop' module, and write the rest yourself
Just found out that this package is no longer under development so here are some active forks:
https://github.com/gamechanger/nodeload
https://github.com/Samuel29/NodeStressSuite
Why couldn't you test a node server with JMeter? For most load tests it doesn't matter what language your server is, you're just hitting it with a bunch of requests.
In any case, you could try loadtest which is implement in node.
Runs a load test on the selected HTTP or WebSockets URL. The API allows for easy integration in your own tests.
Edit:
This answer provides more options:
NodeJs stress testing tools/methods [closed]
Try artillery. Here are its features, the description of which is taken from the documentation:
Multiple protocols: Load test HTTP, WebSocket, Socket.io, Kinesis, HLS and more.
Scenarios: Support for complex scenarios to test multi-step interactions in your API or web app (great for ecommerce, transactional APIs, game servers etc).
Load testing & Functional testing: reuse the same scenario definitions to run performance tests or functional tests on your API or backend.
Performance metrics: get detailed performance metrics (latency, requests per second, concurrency, throughput).
Scriptable: write custom logic in JS, using any of the thousands of useful npm modules.
Integrations: statsd support out of the box for real-time reporting (integrate with Datadog, Librato, InfluxDB etc).
Extensible: write custom reporters, custom plugins, custom protocol engines etc.
and more! HTML reports, nice CLI, parameterization with CSV files.
