no-empty-vitest-bench-include

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

Rule catalog ID: R028

Targeted pattern scope

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

What this rule reports

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

Why this rule exists

An empty benchmark include list often disables benchmark discovery entirely. This rule catches that high-impact config mistake early.

❌ Incorrect

import { defineConfig } from "vitest/config";

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

✅ Correct

import { defineConfig } from "vitest/config";

export default defineConfig({
    test: {
        benchmark: {
            include: ["bench/**/*.bench.ts"],
        },
    },
});

Behavior and migration notes

• this rule checks static empty arrays only
• it does not validate benchmark glob quality

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 benchmark include patterns are injected dynamically and empty committed arrays are intentional placeholders.
