Testing Order Model Version Creation in PaperTrail

This test suite evaluates the versioning functionality of the Order model in PaperTrail, specifically focusing on association tracking during record destruction. It verifies that version records are properly created and maintained when associated records are destroyed, ensuring data history integrity.

Test Coverage Overview

The test suite covers critical versioning behavior for Order model associations, particularly focusing on the destruction lifecycle.

Key areas tested include:

Version record creation for associated models
Proper version count verification after destruction
Customer association tracking

Implementation Analysis

The testing approach utilizes RSpec’s describe and context blocks to organize test scenarios logically. The implementation leverages PaperTrail’s versioning: true flag to enable version tracking during tests, demonstrating proper setup for association-aware versioning tests.

Technical patterns include:

Model factory usage for test data creation
Explicit version count verification
Isolated test context for destruction scenarios

Technical Details

Testing tools and configuration:

RSpec as the testing framework
PaperTrail versioning configuration
Model-level type specification
Frozen string literal pragma
Spec helper inclusion for test setup

Best Practices Demonstrated

The test exemplifies several testing best practices in Ruby and RSpec.

Notable practices include:

Focused test scenarios with clear contexts
Proper setup and teardown of test data
Explicit expectations for version counts
Clean and maintainable test structure
Effective use of RSpec’s described_class
