What does "stub" mean in programming?
stub is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A simplified fake implementation of a dependency used in tests. Unlike a full mock, a stub just returns preset data without verifying how it was called. Stubs replace complex or slow components with simple ones.
Example
"Use a stub that always returns the same user object instead of querying the database."
