We're using Locust for load testing and k6. I came across k6 and I like JavaScript, please suggest which is better for API testing k6 or Locust?

Locust

I am looking for a performance testing tool that I can use for testing the documents accessed by many users simultaneously. I also want to integrate Jenkins with the performance automation tool. I am not able to decide which shall I choose Gatling or Locust. But for me, Jenkins integration is important. I am looking for suggestions for this scenario.

Locust

I have to run a multi-user load test and have test scripts developed in Gatling and Locust.

I am planning to run the tests with Flood IO, as it allows us to create a custom grid. They support Gatling. Did anyone try Locust tests? I would prefer not to use multiple infra providers for running these tests!

Locust Alternatives & Comparisons

What are some alternatives to Locust?

Cicada Shell

It is a simple bash-like Unix shell written in Rust.

Grasshopper

Sound more professional and stay connected with Grasshopper, the Virtual Phone System designed for entrepreneurs. Grasshopper works just like a traditional phone system, but requires no hardware to purchase or software to install.

Gatling

Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance. Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships JMS support.

It is a developer centric open source load testing tool for testing the performance of your backend infrastructure. It’s built with Go and JavaScript to integrate well into your development workflow.

Postman

It is the only complete API development environment, used by nearly five million developers and more than 100,000 companies worldwide.
