Spec File

Noun · Development

Definitions

  1. A file that defines a specification — either a test specification (e.g., user.spec.ts in Jest/Vitest, user_spec.rb in RSpec) containing test cases for a module, or an RPM .spec file that declares how to build, install, and package software into an RPM package for Linux distributions.

    In plain English: A file that describes either the tests for a piece of code or the instructions for building a software package.

    Example: "Every component gets a co-located .spec.tsx file — if there's no spec file, the PR won't pass review."
