Locust is an open source performance and load testing tool for HTTP and other protocols. The tests can be run from the command line or using its web-based UI. Locust’s approach allows defining the tests in regular Python code.
Throughput, response times and errors can be viewed in real time and/or exported for later analysis. Software testers can import regular Python libraries. Locust’s pluggable architecture is expandable.
It is very helpful to verify the capabilities of websites to achieve a small response time when they are under the stress of higher traffic, be it a spike of traffic to a trending MadSlots Casino Review, or a case of a ticketing system for a large music festival like Coachella.

* AI Deploy – Tutorial – How to load test your application with Locust
The aim of this tutorial is to load test with Locust your deployed applications, by gradually querying your APIs with a load testing tool. Usually, your challenge is to forecast your compute needs, for example how many CPUs or GPUs will be required for 1000 API calls per hour and acceptable latency.
* Performance and Load Testing using Locust
If you would like to write user scenarios in plain-old Python using a distributed and scalable tool with a Web-based UI, this article is just for you. Low threshold makes Locust attractive for junior testing engineers, whilst many senior specialists turn to Locust, too, when they get tired of Apache JMeter. Whether you are junior or senior, if you’ve ever wondered how to use Locust for load testing, we are sure you will enjoy this intro, as seamless as it is. After reading it, you will be able to start your load tests in Locust right away.
