Validating System Statistics Configuration in PgHero

This test suite validates system statistics functionality in PgHero, focusing on the enabled state and provider configuration. The tests ensure proper handling of system stats settings and provider detection in the database layer.

Test Coverage Overview

The test suite covers essential system statistics functionality in PgHero.

Key areas tested include:

System stats enablement verification
Stats provider configuration checks
Default state validation

Integration points focus on database layer interaction and configuration management.

Implementation Analysis

The implementation uses Minitest framework with a straightforward approach to system configuration testing. The tests employ assertion patterns specifically designed for boolean and nil checking, utilizing Minitest’s built-in assertion methods refute and assert_nil for validation.

Testing patterns focus on individual configuration aspects in isolation.

Technical Details

Testing components include:

Minitest as the testing framework
Custom test helper integration
Database configuration setup
System stats specific assertions

Best Practices Demonstrated

The test suite demonstrates clean testing practices with focused, single-responsibility test methods. Each test validates a specific aspect of the system stats configuration, following the principle of atomic testing.

Notable practices include:

Clear test method naming
Isolated test cases
Appropriate assertion selection
Minimal test complexity
