Developing GitLab Duo: Secure and thoroughly test AI-generated code

What this post added

This post details the integration of GitLab Duo with GitLab Pages to secure and test AI-generated code. It provides a step-by-step guide for developers to: 1. Create a new project. 2. Enable GitLab Duo Code Suggestions. 3. Create a Flask web server. 4. Generate unit tests using the `/tests` command in Duo. 5. Identify security vulnerabilities and dependency issues using Duo Chat. 6. Generate test reports with a Python script. 7. Deploy test reports using GitLab Pages via a `.gitlab-ci.yml` configuration. 8. Embed test reports in MR widgets. It also includes a case study demonstrating the integration of SAST scanning to detect OS command injection vulnerabilities in AI-generated code.
