Write comprehensive tests using STANDARD test framework syntax (do NOT create custom helper functions):\n - **TypeScript/JavaScript**: Use describe/it/expect blocks from vitest or jest\n - Import framework: `import { describe, it, expect } from 'vitest';`\n - Import functions: `import { functionName } from './filename';`\n - Structure: `describe('feature', () => { it('should...', () => { expect(...).toBe(...) }) })`\n - **Python**: Use pytest with def test_* functions\n - Import: `from filename import ClassName` or `import pytest`\n - Structure: `def test_feature(): assert value == expected`\n - **Rust**: Use #[test] attribute or #[cfg(test)] module\n - Import: `use super::*;` or `use crate::module::*;`\n - Structure: `#[test] fn test_name() { assert_eq!(result, expected) }`\n2. Tests MUST fail initially (no implementation exists yet)\n3. Cover happy path AND edge cases\n4. Include setup/teardown if needed\n5. **CRITICAL: Include ALL necessary import statements at the top of the test file**\n6. **Do NOT create custom test helper functions (Given/When/Then helpers, etc.)**\n\nIMPORTANT: Generate ONLY the test file content. No markdown code blocks, no explanations, just raw code.",
