v0.29.0 contained a lot of interesting features. Have a look at the release notes for details! gRPC is a light-weight open-source RPC framework. It was originally developed by Google, with 1.0 being released in August 2016. Since then, it's gained a lot of attention as well as a wide adoption. In comparison to JSON, which is transmitted as human-readable text, gRPC is binary, making it both faster to transmit and more compact.

The outline of this article is as follows: Most systems are designed to treat users differently based on their identity. Therefore, users are authenticated via various mechanisms and it's often equally important to test the performance of anonymous and authenticated endpoints. One of the most widespread authentication standards used by today's applications is OAuth. In OAuth, we use a trusted third party to verify the identity of the user.

Before the release of k6 v0.27, there was insufficient support for generating constant request rates. Therefore, we introduced a JavaScript workaround by calculating the time it takes for requests to exhaust each iteration of the script. This v0.27 release includes a new execution engine and lots of new executors that cater to your specific needs. It also includes the new scenarios API with lots of different options to configure and model the load on the system under test.

k6 v0.27.0 is finally out! It has been over a year since the k6 team started working on this release, which includes a multitude of new features, improvements, bugfixes and beyond. This release was an effort to redefine performance and load-testing in k6, by introducing a new execution engine and lots of new executors on top, along with the most requested feature, scenarios. It also includes many UX improvements and bugfixes.

As outlined in our rebranding announcement post from Feb 24th, today we're disabling access to v4 projects in the LoadImpact web app at app.loadimpact.com (v3 projects will continue to be available until Dec 31st, 2020). All v4 projects, tests, and test results will henceforth only be accessible from app.k6.io. The same login credentials are valid across the two web apps. Rest assured, no data is going away, it's technically an older of two frontends being sunsetted.

k6 is a developer-centric, free and open-source load testing tool built for making performance testing a productive and enjoyable experience. Using k6, you'll be able to catch performance regression and problems earlier, allowing you to build resilient systems and robust applications.
Quickly build test cases to validate the performance of your APIs or microservices. Validate that your system can handle the expected volume of traffic, and catch SLA/SLO-breaking performance regressions in CI before they reach production.
Built primarily for load testing, k6 tests can with advantage be reused for performance monitoring of your APIs and microservices in production.
Features:
- Seamless scaling to the cloud: Designed to use the same test in a local, distributed or cloud environment. It provides an unified experience for various usage.
- Built for automation: Designed for automating your performance tests. Get Pass/Fail behavior on your performance goals.
- Write tests in Javascript code: Full scripting language to write realistic load tests. Reuse modules and Javascript libraries to build and maintain your test suite.
- Multiple choices for storage: k6 can output test results to various backends and formats (Grafana, DataDog, Kafka, JSON).
- Easy-to-use APIs and CLI: Designed for developers by developers. The k6 API and CLI is intuitive, flexible and powerful.
- High-performance tool: The k6 engine is written in Go making to be one of the best performing load testing tools.
The best developer experience for load testing.
