A sample Python project for exploring Wallaby.py features.

1. Open this project in VS Code with the Wallaby.py extension installed
2. Wallaby.py will start automatically
3. Open test_calculator.py to see real-time test feedback

• Real-time test execution: Open test_calculator.py and notice the LOADED_AT timestamp shown inline next to LOADED_AT #? in test_module_loaded_at. Make any edit to calculator.py (e.g. add a space or change a comment) and save — the timestamp updates instantly, showing the exact time the module was reloaded.
• Fix a bug: The multiply test in test_calculator.py has an intentional error in test_multiply. Fix the assertion and watch the test pass/fail indicators update in real-time.
• Code coverage: Uncomment tests in test_car.py to see coverage change in real-time
• Value Peek: Add #? at the end of any expression to inspect its value
• Logpoints: Right-click the gutter to add a logpoint and inspect values without modifying code
• Time Travel Debugger: Click the Debug code lens above any test to step forward and backward through execution
• Test Story Viewer: Run the Open Test Story command within any test to see the full execution flow in a single view
• Interactive Value Graphs: Log a complex object (e.g. #? on a DeLorean instance) within test_delorean.py, and click the graph icon to visualize it
• AI Integration: Use Wallaby's Copilot Chat integration (Investigate with AI) from the Errors list to debug with AI

• calculator.py / test_calculator.py - Basic arithmetic with a bug to fix, value peek demo
• car.py / test_car.py - Code coverage exploration with print() output
• delorean.py / test_delorean.py - Time Travel Debugger and value graph demo
