The Ontology

The ontology is a queryable canon of software architecture. It holds every principle with its relations and its repair, every term with its definition, every algorithm with its contract, the reasoning that derives them, the layers they live in and how every tension between them is resolved, and every reference from one record to another is a link.

Hidden Dependency

Details

Definition A dependency a component or an operation relies on without declaring it, so it surfaces only at runtime or when an unstated order is broken.

Referenced by Causal Dependency, Dependency Graph, Testability

Distinct from Test Pyramid Inversion: A hidden dependency is an undeclared requirement of a component or an operation, while test pyramid inversion is a suite weighted toward slow end-to-end tests.

Every term in this category is listed as one record, with its kind, its definition and its aliases, the principles whose relations name it, the principle or contract that carries the same name where one exists, and the layer its category belongs to.
