- **CLI:** `--reporter <name>`

- **Config:** [reporters](/config/reporters)

Specify reporters (default, agent, minimal, blob, verbose, dot, json, tap, tap-flat, junit, tree, hanging-process, github-actions)

By default (i.e. if no reporter is specified), Vitest will display summary of running tests and their status at the bottom. Once a suite passes, its status will be reported on top of the summary.

::: tip

When Vitest detects it is running inside an AI coding agent, the [`minimal`](#minimal-reporter) reporter is used instead to reduce output and minimize token usage. You can override this by explicitly configuring the [`reporters`](/config/reporters) option.

:::

You can disable the summary by configuring the reporter:

})

Outputs a minimal report containing only failed tests and their error messages. Console logs from passing tests and the summary section are also suppressed.

::: tip Agent Reporter

This reporter is well optimized for AI coding assistants and LLM-based workflows to reduce token usage. It is automatically enabled when no `reporters` option is configured and Vitest detects it is running inside an AI coding agent. If you configure custom reporters, you can explicitly add `minimal` or `agent`:

```bash [CLI]

npx vitest --reporter=minimal

```ts [vitest.config.ts]

export default defineConfig({

test: {

reporters: ['minimal']

},

})

},

reporters: {
