Generate comprehensive, edge-case test cases using the Gemini API and automatically evaluate your competitive programming solutions right inside VS Code.
Features
Gemini Integration: Automatically parses competitive programming problem links and generates exactly 10 high-quality test cases, complete with descriptions explaining the specific edge cases being tested.
Auto-Execution: Directly runs your active solution file (supports Python, JavaScript/Node.js, C++, and Java) by feeding the generated inputs into stdin and verifying stdout.
Rich UI: View the generated test cases and their execution statuses in a beautiful, responsive Webview panel.
Usage
Setup API Key: Create a .env file in the extension root directory and add GEMINI_API_KEY=your_api_key.
Open your solution: Open your code file (e.g., solution.py or main.cpp).
Open the Panel: Run the command Test Case Generator: Open Panel from the Command Palette (Ctrl+Shift+P).
Generate: Paste the link to a LeetCode or Codeforces problem, and click Generate Test Cases.
Run: Review the generated test cases, then click Run All Test Cases to execute them against your solution.
