FAQPage Schema
How do I build and test software stories in a deterministic environment?

To build and test software stories deterministically, you can automate the process within an isolated git worktree, ensuring consistent execution and adherence to acceptance criteria. This requires a git repository and a product-context.yaml file.

What is the best way to isolate story building from my main git branch?

The best way to isolate story building is using a dedicated git worktree for each story. This maintains workspace isolation, prevents unintended side effects, and ensures a deterministic build environment separate from your main branch.

Do I need a product-context.yaml file to automate story verification?

Yes, you need a product-context.yaml file to automate story verification. This file defines the story specifications and acceptance criteria required by the deterministic build process to verify your code automatically.

How does deterministic execution help with software testing?

Deterministic execution helps software testing by ensuring a consistent and predictable process for building stories from product specifications. This reduces manual errors and guarantees compliance with defined acceptance criteria.

Can I use git worktrees for automated verification of acceptance criteria?

Yes, you can use git worktrees for automated verification of acceptance criteria. The process isolates each story in a separate worktree, runs deterministic builds, and automatically checks if the output meets the specified criteria.

Why should I use automated story building instead of manual feature implementation?

You should use automated story building to reduce ambiguity and ensure adherence to specifications. It provides a controlled environment for implementing features or bug fixes, following best practices for code quality and maintainability while minimizing manual errors.
