Reusable Test Templates and Pipelines | Dataford Interview Questions

How would you write and maintain a library of reusable test templates or CI/CD pipelines using GitLab CI or Jenkins? Implement a resolver for named pipeline templates that inherit steps from at most one parent template. Return the fully ordered steps for a requested template, or None if the target is missing or inheritance contains a cycle. Input is a dictionary of template names to objects containing an optional extends name and a list of string steps.

Constraints

1 <= number of templates <= 500
Each template extends zero or one other template
Each template name is unique
Each step is a string
A valid inheritance chain contains no cycles
Return None for a missing target, missing parent, or cyclic inheritance

Function Signature

def resolve_pipeline(templates, target):
