Validating Version Number String Generation in PaperTrail

This test suite validates PaperTrail’s version number formatting and structure. It focuses on ensuring proper semantic versioning implementation and string representation of version components. The tests verify the correct assembly of major, minor, tiny, and pre-release version segments.

Test Coverage Overview

The test coverage focuses on version number string generation in PaperTrail. It specifically tests:

Version number component concatenation
Proper period-separated formatting
Handling of optional pre-release segments
Integration with semantic versioning standards

Implementation Analysis

The testing approach uses RSpec’s describe and it blocks to organize version number validation. The implementation leverages RSpec’s expectation syntax with described_class to reference the VERSION module dynamically, ensuring maintainable and DRY test code.

The test pattern demonstrates proper encapsulation of version components and validates their assembly into a standardized string format.

Technical Details

Testing Framework: RSpec
Test Environment: Spec helper configuration
Version Components: MAJOR, MINOR, TINY, PRE constants
String Manipulation: Array joining with period delimiter
Null Handling: Compact method for optional components

Best Practices Demonstrated

The test suite exemplifies several testing best practices in Ruby development. It shows proper module namespacing, clear test descriptions, and efficient use of RSpec’s described_class feature. The code maintains single responsibility principle while providing comprehensive version string validation.

Clear test organization
Proper module scoping
Efficient constant handling
Semantic version validation
