🛠️ [fix] Improve path handling and test reliability

Nick2bad4u · Nick2bad4u · commit 9c540a311d04 · 2025-10-26T21:33:34.000-04:00
This update introduces several fixes and enhancements to improve robustness, especially around path resolution and test execution.

*   **Source Code Changes**
    *   🛠️ [fix] Strengthens cache path resolution by adding error handling for `[System.IO.Path]::IsPathRooted`. This prevents crashes when processing paths with invalid characters, returning `null` instead.

*   **Testing and Build Changes**
    *   🧪 [test] Updates tests to be more resilient and accurate.
        -   Improves test state management by using `try...finally` blocks to correctly restore environment and global variables, ensuring test isolation.
        -   Refines assertions to be more specific, particularly for cache path and text emission tests, to correctly reflect behavior under different conditions (like output redirection).
        -   Corrects a potential issue in a test by ensuring a `Where-Object` result is always treated as an array.
    *   👷 [ci] Enhances the module test script (`Test-Module.ps1`).
        -   Introduces a helper function to reliably retrieve the module's cache directory, even if it hasn't been initialized yet.
        -   Skips the PSScriptAnalyzer test with a warning if the module is not installed, preventing script failure in environments without it.
    *   🧹 [chore] Bumps the module version and updates related help files.
