Testing Strategy Registration and Configuration in factory_bot

This test suite validates core functionality of FactoryBot, focusing on strategy registration and parent strategy behavior. It ensures the library correctly manages factory strategies and maintains expected default configurations.

Test Coverage Overview

The test suite provides essential coverage for FactoryBot’s strategy management system.

Key areas tested include:

Strategy registration and retrieval functionality
Default parent strategy behavior verification
Core configuration settings validation

Implementation Analysis

The testing approach employs RSpec’s describe/it blocks to organize related test cases logically. The implementation uses direct FactoryBot method calls to verify strategy registration and configuration settings, demonstrating clean isolation of test concerns.

Technical patterns include:

Strategy registration verification
Boolean configuration testing
Expectation matching with RSpec matchers

Technical Details

Testing tools and configuration:

RSpec testing framework
FactoryBot test helpers
Strategy registration API
Configuration property access

Best Practices Demonstrated

The test suite exhibits several testing best practices for Ruby libraries.

Notable practices include:

Isolated test cases for specific functionality
Clear test descriptions using RSpec’s natural language syntax
Proper scoping of test contexts
Direct assertion of expected behaviors
