browser.commands #

• Type: Record<string, BrowserCommand>
• Default: { readFile, writeFile, ... }

Custom commands that can be imported during browser tests from vitest/browser.

::: warning Security Commands run in the Vitest Node process. If a command exposes filesystem, process, network, database, or shell access based on browser-provided input, validate and restrict that input inside the command. Built-in file commands apply Vite server.fs checks and write-access checks, but custom commands are responsible for their own protections.

See Custom Commands security notes. :::
