Testing PostgreSQL Sequence Management in PgHero

This test suite validates PostgreSQL sequence operations in PgHero, focusing on sequence identification and threshold monitoring. The tests ensure proper sequence detection and danger level assessment for database sequences.

Test Coverage Overview

The test suite covers essential sequence management functionality in PgHero.

Key areas tested include:

Sequence identification and retrieval
Danger level assessment with configurable thresholds
Validation of sequence naming patterns

Integration points focus on database sequence operations and threshold-based monitoring.

Implementation Analysis

The testing approach utilizes Minitest for straightforward unit testing of sequence-related features. The implementation employs assertion-based verification patterns to confirm sequence presence and danger level detection, with particular attention to threshold configuration capabilities.

Key patterns include direct database interaction and conditional sequence filtering.

Technical Details

Testing components include:

Minitest as the testing framework
Test helper integration for database connectivity
Database sequence manipulation utilities
Custom assertion methods for sequence validation

Best Practices Demonstrated

The test suite exemplifies clean testing practices with focused test methods and clear assertions. Notable practices include:

Isolated test cases for specific functionality
Parameterized threshold testing
Consistent sequence naming conventions
Efficient database query patterns
