Testing Git Stash Pop Conflict Resolution in TheFuck

This test suite validates the functionality of git stash pop command handling in the TheFuck project, specifically focusing on conflict resolution scenarios. It ensures proper behavior when local changes would be overwritten during stash pop operations.

Test Coverage Overview

The test suite provides comprehensive coverage of git stash pop command handling, focusing on error detection and command correction.

Key areas tested include:

Error message matching for merge conflicts
Command transformation logic for resolving stash conflicts
Negative test cases for non-matching scenarios

Implementation Analysis

The testing approach utilizes pytest fixtures to simulate git command outputs and verify command matching behavior. The implementation follows a pattern of separate match and command generation tests, ensuring both error detection and correction logic work as expected.

Framework features utilized:

Pytest fixtures for test data setup
Assert statements for verification
Command object usage for input/output handling

Technical Details

Testing tools and configuration:

Pytest as the primary testing framework
Custom Command type for command representation
Fixture-based test data management
Module-level function testing

Best Practices Demonstrated

The test suite demonstrates several testing best practices including isolation of test cases, clear arrangement of test scenarios, and proper use of fixtures. Notable practices include:

Separate positive and negative test cases
Clear test function naming
Fixture usage for reusable test data
Focused unit test scope
