Highlights 💡

Introducing Markdown reporter for agent 🤖

Rstest automatically detects AI coding agent (Claude Code, Cursor, Codex, opencode, etc.) and switches to Markdown output — no configuration needed.

The structured Markdown format is easier for LLMs to parse and understand compared to traditional terminal output. Each failure includes a one-click repro command so agents can quickly rerun and debug individual test cases. Output is intelligently truncated to stay within context limits even when many tests fail, saving tokens and reducing cost.

For detailed configuration options, see https://rstest.rs/guide/basic/reporters#markdown-reporter.

Introducing Browser mode (experimental)

Run UI tests in real browsers (Chromium / Firefox / WebKit) via Playwright — validate real rendering/layout + browser-native APIs, debug visually in the built-in UI, and iterate faster with watch-mode re-runs on source changes.

• Getting started
• Config reference
• Example (Rsbuild + React)

Note: Browser mode is still experimental — we’re just getting started: more providers, more framework integrations, and, AI.
