no-empty-vitest-project-exclude

Disallow empty project-level test.exclude arrays in workspace/project entries.

Rule catalog ID: R033

Targeted pattern scope

• vitest.workspace.*
• inline project entries in test.projects
• nested project test.exclude values only

What this rule reports

This rule reports empty project-level test.exclude: [] arrays.

Why this rule exists

Project-level empty excludes are often leftover placeholders that imply filtering but do nothing. Keeping these entries explicit and non-empty improves project topology clarity.

❌ Incorrect

import { defineWorkspace } from "vitest/config";

export default defineWorkspace([
    {
        test: {
            name: "unit",
            exclude: [],
        },
    },
]);

✅ Correct

import { defineWorkspace } from "vitest/config";

export default defineWorkspace([
    {
        test: {
            name: "unit",
            exclude: ["dist/**"],
        },
    },
]);

Behavior and migration notes

• this rule checks nested project excludes only
• use no-empty-vitest-exclude for root-level test.exclude

ESLint flat config example

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

export default [vite.configs.strict, vite.configs.vitest];

When not to use it

Disable this rule only if your project generator intentionally emits empty nested exclude arrays as templates.
