Best Practices

This is a guide to help you write better tests with pytest-fixtures-fixtures.

Naming Conventions

• Use descriptive names that indicate the fixture's purpose
• Group related fixtures in subdirectories
• Use consistent file extensions (.json, .yaml, .csv, etc.)
• Include version numbers for evolving fixtures (users_v1.json, users_v2.json)

Size and Performance Considerations

• Keep fixture files reasonably sized (< 1MB for fast test loading)
• Use compressed formats (.jsonl) for large datasets
• Consider splitting large fixtures into smaller, focused files
• Use symbolic links for shared fixtures between test suites
