Your task is to create comprehensive, high quality test cases for the {% block task_target %}{{ function_name }}{% endblock %} function.

**1. Basic Test Cases**:
- **Objective**: To verify the fundamental functionality of the {{ function_name }} function under normal conditions.

**2. Edge Test Cases**:
- **Objective**: To evaluate the function's behavior under extreme or unusual conditions.

**3. Large Scale Test Cases**:
- **Objective**: To assess the function's performance and scalability with large data samples.

<instructions>
- Implement a comprehensive set of test cases following the guidelines above.
{% block framework_instruction %}- Use the testing framework specified in the user message with `describe`, `test`/`it`, and `expect`.{% endblock %}
- Ensure each test case is well-documented with comments explaining the scenario it covers.
- Pay special attention to edge cases as they often reveal hidden bugs.
- For large-scale tests, focus on the function's efficiency and performance under heavy loads. Avoid loops exceeding 1000 iterations, and keep data structures under 1000 elements.
{% block determinism_rule %}{% endblock %}
- **CRITICAL: DO NOT MOCK THE FUNCTION UNDER TEST** - Never mock, stub, or spy on the {{ function_name }} function itself. You may mock external dependencies (APIs, databases, network calls, file I/O, etc.) if necessary, but the function being tested must execute with its real implementation.
- **CRITICAL: IMPORT FROM REAL MODULES** - Import the function and any related classes/utilities from their actual module paths as shown in the context.
- **CRITICAL: HANDLE ASYNC PROPERLY** - If the function is async, use `async/await` in your tests and ensure all promises are properly awaited.
{% block extra_instructions %}{% endblock %}
</instructions>
{%- block framework_rules %}

<rules>
**CRITICAL: IMPORT PATH RULES**:
- **NEVER add file extensions (.js, .ts, .tsx) to import paths** - The test framework resolves extensions automatically.
- **WRONG**: `import { fn } from '../utils.js'` or `import { fn } from '../utils.ts'`
- **CORRECT**: `import { fn } from '../utils'`
- The user message provides the exact import statement to use - copy it exactly without modification.

**CRITICAL: VITEST IMPORTS REQUIRED**:
- If test_framework is "vitest", you MUST import test functions from 'vitest' since globals are NOT enabled by default:
  ```javascript
  import { describe, test, expect, vi, beforeEach, afterEach } from 'vitest';
  ```
- For "jest", globals are typically enabled so no import is needed.

**CRITICAL: MOCKING RULES**:
- **USE THE CORRECT MOCK SYNTAX FOR THE SPECIFIED FRAMEWORK**:
  - For **Jest**: Use `jest.mock()` and `jest.fn()`
  - For **Vitest**: Use `vi.mock()` and `vi.fn()` - NEVER use jest.mock with Vitest!
- Mock calls are HOISTED to the top of the file. NEVER use dynamic expressions - use static string literals only.
- **ALWAYS use static string literals** for mock paths.
- **IMPORTANT**: Check the test framework specified in the user message and use the matching syntax.
