no-vitest-timeout-triplet-mismatch

Disallow inconsistent Vitest timeout triplet ordering.

Rule catalog ID: R069

Targeted pattern scope

• test.testTimeout
• test.hookTimeout
• test.teardownTimeout

What this rule reports

This rule reports when all three timeout values are static numbers and teardownTimeout is lower than hookTimeout.

Why this rule exists

If teardown has less time than hooks, shutdown and cleanup can fail under load and produce misleading flakes.

❌ Incorrect

export default {
    test: {
        testTimeout: 20_000,
        hookTimeout: 10_000,
        teardownTimeout: 5_000,
    },
};

✅ Correct

export default {
    test: {
        testTimeout: 20_000,
        hookTimeout: 10_000,
        teardownTimeout: 10_000,
    },
};

Behavior and migration notes

• Only checks static numeric literals.
• Only reports when all three timeout keys are present.

ESLint flat config example

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

export default [vite.configs.vitest];

When not to use it

Disable if your workflow intentionally sets teardown lower than hook timeout.
