Circular dependency

As explained in AI-Powered Developer: Build software with ChatGPT and Copilot

A circular dependency is a dependency relationship in which two or more modules or components depend on one another directly or through an intermediate dependency.

How AI-Powered Developer: Build software with ChatGPT and Copilot covers it

How deep it goes

Defines direct and indirect cycles, demonstrates their failure point, and sketches decoupling fixes without detailing broader dependency-management patterns.

Examples

Uses a visitor, Asset, FundingDetails, and DepreciationStrategy cycle, then shows revised class references.

What it assumes

Assumes familiarity with Python classes and unit tests while defining circular dependencies from the failing example.

What you can do after

Diagnose/debug with unit-test failures and reduce cycles by removing direct class instantiation or references.

How it connects

Connects unit testing with Python classes, modules, components, and integration testing.
