Real-Time Coverage WebSocket Push Feature

[zhangtao25]

Description:

I would like to propose adding a real-time coverage WebSocket push feature to Canyon.

Overview:

The idea is to enable real-time coverage data updates for applications connected to the server. This would work as follows:

1. When an application connects to the server, the server pushes the current coverage data for that application in real-time via WebSocket.
2. A dedicated web page will be provided to display the real-time coverage data for connected applications.

Benefits:

• Provides immediate visibility into coverage changes during runtime.
• Facilitates debugging and analysis for developers by showing real-time metrics.

Suggested Implementation:

1. WebSocket Server:

   • Add WebSocket endpoints to the backend service (canyon-backend) to handle connections and push coverage updates.
   • Ensure the connection is associated with the correct application context.

2. Real-Time Coverage Updates:

   • Trigger WebSocket messages whenever there are updates in the coverage data (e.g., new reports received, changes processed).
   • Optimize data format for minimal bandwidth usage.

3. Web UI:

   • Create a new page or module in canyon-platform for visualizing real-time coverage data.
   • Include key metrics (e.g., percentage coverage, number of hits, module-level breakdown) and update the view dynamically.

4. Security:

   • Add authentication and authorization mechanisms to ensure only authorized users can connect and view data for a specific application.

Potential Challenges:

• Managing high-frequency updates for large applications with extensive coverage data.
• Ensuring scalability when multiple applications are connected simultaneously.
