Concepts

Dummy Object - A test double passed around to fill parameter lists but never actually used, serving only to satisfy method signatures or constructor requirements.
Microservices Architecture - A distributed architecture style that structures an application as a collection of small, autonomous services organized around business capabilities.
Stale-While-Revalidate (SWR) - A caching strategy that returns cached data while fetching updated data in the background.
Punctuated Equilibrium - Long periods of stability interrupted by brief periods of rapid, dramatic change.
Clean Architecture - A software architecture pattern that emphasizes separation of concerns through concentric layers with dependencies pointing inward.
Modulith - A modular monolith architecture that combines the simplicity of monoliths with the organizational benefits of microservices.
Bounded Context - A central pattern in Domain-Driven Design that defines explicit boundaries within which a domain model is defined and applicable.
Bottom-Up Analysis - An analytical approach that starts with specific details and builds upward to understand larger patterns and systems.
Unsupervised Learning - A machine learning approach where models find patterns in data without labeled examples or predefined outcomes.
Self-Organization - The process where order and structure spontaneously emerge from local interactions between components without central control or external direction.
Nonlinearity - When outputs are not proportional to inputs, and small changes can produce disproportionately large or small effects.
Story Arcs - Universal narrative patterns that describe the emotional trajectory of stories, from 'Rags to Riches' to 'Man in a Hole.'
Test Double - A generic term for any object that replaces a production dependency during testing, including dummies, fakes, stubs, spies, and mocks.
Test Spy - A test double that records information about how it was called, allowing verification of interactions after the code under test has executed.
Emergence - The phenomenon where complex systems exhibit properties and behaviors that their individual components do not possess on their own.
Success Principles - Timeless patterns and practices that consistently contribute to achievement across domains.
Innovation Diffusion - How innovations spread through populations over time following predictable patterns.
Mock Object - A test double pre-programmed with expectations about calls it should receive, used to verify interaction behavior between objects under test.
Test Stub - A test double that provides canned answers to calls made during a test, replacing real dependencies with predictable, pre-programmed responses.
Service-Oriented Architecture - An architectural style that organizes software as a collection of interoperable services that communicate through standardized interfaces.
Visual Consistency - Maintaining uniform design elements and patterns across a product or system to create predictability and ease of use.
Failure Patterns - Recurring types of failures that share common characteristics and causes.
Hysteresis - A system property where its current state depends on its history, not just current conditions.
Test Fake - A test double with a working but simplified implementation that takes shortcuts unsuitable for production, such as an in-memory database.
Monolithic Architecture - A software architecture pattern where an entire application is built as a single, unified unit.
