korra | Session-based load testing using text files

korra is a Go library. korra has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Korra builds on Vegeta to process sessions that simulate one or many users moving through a prescribed workflow. This is quite different from typical load testing tools , and if you're trying to flood your site with customers randomly browsing your product catalog you should use something like:. or any of a number of other, far more mature tools. (This presentation might provide some additional background on that.). So each concurrent session that Korra processes is backed by a script, which is just an ordered sequence of simple actions. How you generate this script is up to you. It's plain text and in a straightforward format very similar to Vegeta, allowing custom headers and body per request along with additional directives to pause between steps, or poll a URL until a specified halt condition. It walks through these actions one at a time in a session, logging information about each transaction. Every session is separate from every other session, and we use Go's concurrency model to potentially represent many thousands of users on a single node. Once all sessions are complete you can report on the results. Transaction results can be dumped to JSON or CSV formats so you can process with your favorite tools, and there are some simple reports Korra can generate out of the box.
