Postman (API Tester)

Overview

The Postman screen is a powerful, integrated development tool for testing and debugging the robot's internal and external APIs. It allows developers to send direct commands to the backend without using the standard UI, making it an essential tool for system discovery and rapid integration testing.

Key Features

• Integrated Request Builder: Compose and send custom HTTP requests (GET, POST, PUT, DELETE) directly from the robot's interface.
• Protocol Support: Test standard REST endpoints, WebSocket triggers, and internal ROS service calls.
• History Tracking: Quickly access and re-run previously sent requests to speed up repetitive testing.
• Response Inspector: View the full technical response from the robot's backend, including headers, status codes, and JSON bodies.
• Predefined Collection: Access a built-in library of common robot commands to see how the system reacts "under the hood."

User Workflow

1. API Exploration: A developer wants to see what the raw data looks like for the robot's "Battery Stats" and builds a quick GET request.
2. Integration Testing: Before building a new automated script, the user tests the "Trigger Door Open" API endpoint through Postman to ensure it works.
3. Troubleshooting: If the UI isn't updating, the developer sends a direct request to verify that the robot's backend is still responding correctly.
4. Command Iteration: The user modifies a "GoTo" request's parameters (coordinates) and re-sends it until the desired robot behavior is achieved.
