GitHub Copilot has evolved to offer asynchronous code testing, allowing users to set up code testing autonomously.The new Copilot Agent can navigate, edit files, run commands, and open pull requests to check, test, and iterate code.Developers can assign issues to Copilot Agent, which works more autonomously, freeing developers to focus on other tasks.GitHub Copilot now competes with other AI coding tools like ChatGPT, Google’s Code Assist, and OpenAI’s Codex in the AI coding assistant space.
