[benfdking]

• cleans up tem dir after every test

[Copilot]

Pull Request Overview

This PR centralizes temporary directory creation for VSCode extension tests by moving it to a reusable fixture. This eliminates code duplication across test files where each test was creating its own temporary directory, and ensures automatic cleanup after each test completes.

• Moves temp directory creation from individual tests to a central tempDir fixture in fixtures.ts
• Updates all test files to use the new tempDir parameter instead of creating directories manually
• Adds automatic cleanup of temporary directories after each test

Using @ts-expect-error to suppress TypeScript errors is not a good practice. Consider fixing the underlying type issue or using a more specific type annotation instead of suppressing the error.

The function signature change removes the return of tempDir but the return type still includes it in the destructuring pattern. This creates an inconsistency between what the function returns and what callers expect.
