FixtureKit Wiki

FixtureKit speeds up test setup by caching fixture data as SQL and replaying it quickly inside your test transactions.

Start Here

1. Follow Getting Started to run your first fixture end to end.
2. Compare options in FixtureKit vs Alternatives.
3. Choose your framework:

• Using Fixtures in RSpec
• Using Fixtures in Minitest

4. Use Declaring Fixtures for named vs anonymous fixture patterns.
5. Use Configuration and Adapters for behavior tuning.
