Redis Configuration Precedence Testing

A test suite that validates configuration precedence in a Redis fixture system.

Capabilities

Configuration Hierarchy Validation

Create a test suite that verifies configuration precedence behavior. The system supports three levels: factory arguments (highest), command-line options (medium), and pytest.ini settings (lowest).

• A custom Redis fixture configured only via pytest.ini uses port 6380 @test
• The same fixture with a CLI option --redis-port=6381 uses port 6381 instead @test
• The same fixture with factory argument port=6382 uses port 6382, ignoring CLI and ini settings @test

Implementation

@generates

Requirements

Create a test file with:

1. A pytest.ini configuration file that sets redis port to 6380
2. Three test functions that validate the precedence hierarchy
3. Custom Redis fixtures created using factory functions that accept configuration parameters
4. Assertions that verify the correct port is used in each scenario

All tests should pass when configuration precedence works correctly.
