| 36 | .SYNOPSIS |
| 37 | Detects changed PowerShell files and resolves corresponding Pester test paths. |
| 38 | .DESCRIPTION |
| 39 | Runs git diff against the specified base branch to find changed .ps1/.psm1 files, |
| 40 | then maps each changed source file to its corresponding test file by searching |
| 41 | test directories including skill test folders at depth 1 and 2. |
| 42 | .PARAMETER BaseBranch |
| 43 | The base branch to diff against (e.g., 'main'). |
| 44 | .PARAMETER FileFilter |
| 45 | File extensions to include in the diff (default: *.ps1, *.psm1). |
| 46 | .PARAMETER SkillsRoot |
| 47 | Root directory for skill packages containing test folders. |
| 48 | .PARAMETER TestRoot |
| 49 | Root directory for script tests. |
