no-empty-vitest-bench-exclude

Disallow empty test.benchmark.exclude arrays in Vitest config.

Rule catalog ID: R029

Targeted pattern scope

• vitest.config.*
• vitest.workspace.*
• vite.config.* when benchmark options are used
• test.benchmark.exclude

What this rule reports

This rule reports test.benchmark.exclude: [].

Why this rule exists

An empty benchmark exclude list is usually redundant config noise. Removing ineffective settings keeps benchmark topology easier to reason about.

❌ Incorrect

import { defineConfig } from "vitest/config";

export default defineConfig({
    test: {
        benchmark: {
            exclude: [],
        },
    },
});

✅ Correct

import { defineConfig } from "vitest/config";

export default defineConfig({
    test: {
        benchmark: {
            exclude: ["dist/**"],
        },
    },
});

Behavior and migration notes

• this rule checks static empty arrays only
• it does not enforce that an exclude list must exist

ESLint flat config example

import vite from "@typpi/eslint-plugin-vite";

export default [vite.configs.strict, vite.configs["vitest-bench"]];

When not to use it

Disable this rule only if your workflow intentionally keeps empty benchmark excludes as placeholders.
