项目历史

Locust's official history page says it was created out of frustration with existing tools such as Apache JMeter and Tsung. The objection was both ergonomic and architectural: graphical point-and-click test design made complex scenarios hard to maintain, and thread-bound approaches limited concurrency.

The project was created in 2011 by Carl Bystrom and Jonatan Heyman while they were working on Battlelog, the companion app for Battlefield 3. That origin explains Locust's emphasis on simulating many concurrent users while keeping test behavior programmable.

The official repository describes Locust as an open source performance/load testing tool for HTTP and other protocols, with tests defined in regular Python code. Its docs grew to cover configuration files, distributed load generation, Docker, headless operation, web UI customization, and hosted load testing.

采用历史

Locust adoption spread among Python teams and service developers who wanted load tests in the same language and version-control workflow as application code. The official Locust Cloud retrospective describes the project as reaching thirteen years and tens of millions of downloads, indicating broad use beyond its original game-service context.

The 1.0 release was a significant API cleanup: the changelog documents renaming `Locust` and `HttpLocust` classes to `User` and `HttpUser`, changing client-count terminology to users, and enabling task declarations directly on User classes. Later 2.x releases continued that modernization while preserving the package's code-first model.

使用方式

A normal Locust project defines user behavior in a Python locustfile, then runs `locust` to open the web UI or uses headless command-line options in CI. The configuration docs list CLI flags, environment variables, and config-file keys for the same settings.

Locust looks for `~/.locust.conf`, `./locust.conf`, and `./pyproject.toml` by default, with `--config` available for an additional file. No official credentials file is documented for the open source CLI.

为什么软件包爱好者会关心

Locust is important to package nerds because it is a Python CLI that is also a test framework, a web application, and a distributed worker system. Packaging has to account for Python versions, transitive networking dependencies, and executable entry points.

It is also culturally important as a counterpoint to GUI-first load-testing tools: install a package, commit a locustfile, and scale from a local smoke test to distributed load generation.
