New task: Set up CI/CD pipeline from scratch

[jackjin1997]

Domain: Multi-step (Hard). Agent must create a complete GitHub Actions CI/CD pipeline for a Python project. Looking for fixture design.

I'm a bit confused about the fixture design for the CI/CD pipeline - can you clarify what you mean by "fixture design" in this context? Are you referring to the test fixtures used in the pipeline, or something else entirely?
