This extension leverages OpenAI's API to automatically generate comprehensive unit tests for your code in JavaScript, TypeScript, and Python. It analyzes your code—including its relative import statements—to provide context and generate tests that aim for 100% code coverage.
Features
Automatic Unit Test Generation:
Generate complete unit tests for the open file or via the Explorer context menu with a single command.
Context-Aware Testing:
The extension extracts relative import statements (e.g., import './module' or require('../module')) from your code to provide additional context for generating more accurate tests.
100% Coverage Focus:
Instructs the AI to create tests that cover every function, branch, and edge case in your code, ensuring full coverage.
Multi-Language Support:
Works with JavaScript, TypeScript, and Python files.

Requirements
A valid OpenAI API key is required to use this extension.
An active internet connection to send requests to the OpenAI API.
Visual Studio Code version 1.76.0 or higher.
Extension Settings
This extension contributes the following settings (accessible via VS Code's Settings UI):
openai-unit-test-generator.apiKey
Your OpenAI API key.
openai-unit-test-generator.mainModel
The primary OpenAI model to use for generating unit tests (default: o3-mini).
openai-unit-test-generator.fallbackModel
The fallback OpenAI model to use if the primary fails (default: o3-mini).
Known Issues
Generated tests might occasionally miss some edge cases if the source code is highly complex.
Ensure that your API key is valid and that you have a stable internet connection.
If tests fail to run or cover all paths, try generating tests again or check your code for unusual constructs.
