Test setup
Test setup is the preparation of data, dependencies, state, and execution conditions required before a software test runs.
Django in Action
setUp is a test lifecycle method invoked before each test method to prepare its required state.
- How it is used
- Prepares database-backed state before each Django test method.
- How deep it goes
- Explains invocation timing, ORM fixture creation, test-case attributes, and isolation through transaction rollback.
- Examples
- Uses a Musician fixture to test a view’s status code, response context, and rendered content.
- What you can do after
- Build repeatable Django tests by preparing ORM fixtures once per test method.
The Well-Grounded Rubyist, Fourth Edition
A setup method is a test-support method that prepares the state required before a test method runs.
- How it is used
- Prepares per-test fixtures so test methods can exercise behavior against predictable, independent state.
- How deep it goes
- Explains MiniTest convention and demonstrates callback-based execution, stopping short of broader fixture lifecycle behavior.
- Examples
- Uses a PlayingCards::Deck fixture, one-card and five-card dealing tests, and a MicroTest implementation.
- What you can do after
- Apply it via MiniTest by defining setup to initialize state before each test method.
