From fe679b36a6ddaf8c30be68381599c9d078fa9173 Mon Sep 17 00:00:00 2001 From: Rahul Vadisetty Date: Fri, 23 Aug 2024 10:47:01 +0500 Subject: [PATCH] meta_ai.py In this commit, I have integrated several AI-driven features into the testing and mocking framework. These enhancements aim to automate and improve various aspects of the testing process, leveraging AI models to provide more intelligent and efficient testing capabilities. Key Features Added: 1. AI-Based Test Case Generation: - Introduced a `generate_test_cases` function that uses an LLM (Language Learning Model) to generate test cases based on the provided context. This feature automates the creation of diverse and relevant test cases, reducing manual effort and improving test coverage. 2. AI-Driven Code Review: - Integrated an `ai_review_code` function that reviews code for potential improvements. This feature uses AI to analyze the codebase and suggest optimizations, best practices, and potential bug fixes, leading to cleaner and more maintainable code. 3. AI-Powered Mock Data Generation: - Implemented an `ai_generate_mock_response` function to create mock responses automatically. This feature leverages AI to generate realistic and context-aware mock data, which enhances the accuracy and reliability of tests that rely on mock objects. 4. AI-Driven Error Detection and Correction: - Added an `ai_error_correction` function that detects and corrects errors in the code. This feature utilizes AI to identify potential issues in the code and automatically provides fixes, reducing debugging time and improving code quality. 5. AI-Assisted Documentation Generation: - Provided an `ai_generate_docs` method to automatically generate documentation for the test suite. This feature uses AI to create detailed and accurate documentation, ensuring that the code is well-documented and easier to understand and maintain. These enhancements significantly boost the intelligence of the testing framework, allowing it to generate tests, review code, create mock data, and document itself with minimal human intervention. The integration of AI into these processes ensures higher efficiency, better test coverage, and improved code quality. --- meta_ai.py | 258 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 258 insertions(+) create mode 100644 meta_ai.py diff --git a/meta_ai.py b/meta_ai.py new file mode 100644 index 000000000..23b51e993 --- /dev/null +++ b/meta_ai.py @@ -0,0 +1,258 @@ +import asyncio +import json +import logging +import os +import re +import uuid +from pathlib import Path +from typing import Callable + +import aiohttp.web +import pytest + +from metagpt.const import DEFAULT_WORKSPACE_ROOT, TEST_DATA_PATH +from metagpt.context import Context as MetagptContext +from metagpt.llm import LLM +from metagpt.logs import logger +from metagpt.utils.git_repository import GitRepository +from metagpt.utils.project_repo import ProjectRepo +from tests.mock.mock_aiohttp import MockAioResponse +from tests.mock.mock_curl_cffi import MockCurlCffiResponse +from tests.mock.mock_httplib2 import MockHttplib2Response +from tests.mock.mock_llm import MockLLM + +RSP_CACHE_NEW = {} #
