Walkthrough

The changes focus on improving test reliability and fixture management. The test setup and teardown now preserve the working directory across tests, and fixture handling is enhanced to support local overrides and recursive copying. Additionally, comments in the mock setup file were translated from Japanese to English without altering functionality.

Changes

File(s)	Change Summary
tests/index.test.js	Enhanced test setup/teardown to save and restore the working directory before and after each test to prevent directory-related issues.
tests/setup-mocks.js	Translated all inline comments from Japanese to English; no changes to logic or mock implementations.
tests/setup.js	Improved fixture handling: finds project root via package.json, supports local fixture overrides, recursively copies fixtures, and creates mock fixtures if missing. Removed a commented line from cleanup.

Poem

In the warren of tests, we hop with care,
Directories safe, no path unaware.
Fixtures now travel, both near and far,
With English notes guiding us like a star.
🐇✨ Our code hops forward, neat and bright—
Every test burrow set just right!

tests/setup.js (4)

20-30: Good implementation of project root detection.

This addition properly finds the project root by traversing upward until it locates a package.json file, which is a reliable way to identify the root directory in a Node.js project.

---

36-63: Well-structured fixture handling with recursive directory support.

This enhancement properly copies all fixture files and handles subdirectories recursively, which improves test robustness. The implementation correctly:

1. Creates a dedicated fixtures directory
2. Properly copies files from source to destination
3. Recursively handles subdirectories like 'expected'
4. Uses appropriate error handling with existence checks

---

84-93: Good enhancement to fixture lookup strategy.

This improvement supports local overrides by first checking the current working directory for fixtures before falling back to project-level fixtures. This provides more flexibility in test scenarios.

---

146-148: PR objective completed: Japanese comment removed.

The Japanese comment has been successfully removed from the cleanupTestRepo function as intended per the PR objectives.

tests/setup-mocks.js (3)

24-49: Successfully translated comments to English.

The Japanese comments in the index.js module mock have been properly translated to English while preserving the functional behavior of the mocks.

---

52-79: Successfully translated fs module mock comments.

All Japanese comments in the fs module mock implementation have been properly translated to English without altering the functionality.

---

81-96: Successfully translated remaining mock comments.

All remaining Japanese comments for commander, child_process, prompts module mocks, and process.exit have been properly translated to English without changing the mock implementations.

Also applies to: 98-130, 132-143

tests/index.test.js (2)

14-22: Good implementation of working directory preservation.

This change properly stores the original working directory before running each test, which helps maintain a consistent environment across tests.

---

25-32: Proper cleanup with directory restoration.

The implementation correctly changes back to the original directory before cleanup, which prevents issues where test directories might not be properly accessible or removable due to changed working directory.
