+# vitest preset
+
+## Purpose
+
+Правила для тестов (`*.test.*`, `*.spec.*`, `test/**`, `__tests__/**`).
+
+## Key Rules
+
+- `vitest/no-conditional-tests`.
+- `vitest/no-import-node-test`.
+- `vitest/prefer-to-be-truthy`, `vitest/prefer-to-be-falsy`.
+- `vitest/prefer-to-have-length`.
+- Relaxations: `eslint/no-unused-vars` и `typescript/no-explicit-any` выключены для тестов.
+
+## Examples
+
+```ts
+// ✅ Good
+import { describe, it, expect } from 'vitest';
+
+describe('list', () => {
+  it('has items', () => {
+    expect([1, 2, 3]).toHaveLength(3);
+    expect(true).toBeTruthy();
+  });
+});
+
+// ❌ Bad
+if (process.env.CI) {
+  it('conditionally runs', () => {
+    expect(true).toBe(true);
+  });
+}
+```
