Subject: [PATCH 01/15] feat: Implement testing and security framework

This commit introduces a comprehensive, multi-language testing and security framework.

- Adds a .pre-commit-config.yaml with hooks for linting (markdown, yaml, powershell), formatting (prettier), and secret scanning (gitleaks).
- Establishes a 	ests/ directory with a unit test for the existing PowerShell script using Pester.
- Implements a GitHub Actions CI workflow (.github/workflows/ci.yml) to run linters and tests automatically on pull requests.
- Adds TESTING.md to document the local testing setup.
- Includes .vscode/ settings for recommended extensions and tasks.
- Updates CONTRIBUTING.md and Copilot instructions to enforce a test-focused development approach, emphasizing edge case testing.

+# Copilot Instructions for the 'Scripts' Repository
+
+When making changes to this repository, you MUST follow the established testing and security framework.
+
+## 1. Pre-Commit Hooks are Mandatory
+
+This repository uses `pre-commit` to enforce code quality, formatting, and security checks.
+
+- **After making ANY file modifications**, you MUST run the local linter to ensure your changes are compliant. Simulate this by stating you are running the command:
+  ```bash
+  pre-commit run --all-files
+  ```
+- If any hooks fail, you MUST fix the reported issues before proceeding.
+
+## 2. Testing is Required
+
+All new scripts or modifications to existing scripts MUST be accompanied by tests.
+
+- **Test Location:** Tests are located in the `tests/` directory, organized by unit, integration, etc., and then by language.
+  - Example: `tests/unit/PowerShell/`
+- **PowerShell:** New PowerShell scripts require new Pester tests. Add them in the appropriate directory.
+- **Running Tests:** To validate your changes, run the appropriate test command. For PowerShell, this is:
+  ```powershell
+  Invoke-Pester -Path 'tests/unit/PowerShell'
+  ```
+
+## 3. Continuous Integration (CI)
+
+- A CI workflow is located at `.github/workflows/ci.yml`.
+- This pipeline automatically runs all `pre-commit` checks and all Pester tests.
+- All changes must pass CI. Ensure your local checks are passing before you consider your task complete.
+
+## 4. Emphasize Edge Case Testing
+
+As a repository focused on quality, all scripts must be robust. When creating or modifying scripts, you are expected to:
+
+- **Identify and Test Edge Cases:** Explicitly consider and test for null inputs, empty strings, zero values, large inputs, and unexpected data types.
+- **Validate and Sanitize All Inputs:** Assume all input is untrustworthy.
+- **Ensure Graceful Failure:** Scripts should fail with clear, actionable error messages, especially for permission errors or missing dependencies.
+
+## 5. Adding New Languages
+
+When adding a script for a new language (e.g., Python, Bash):
+
+1.  **Update Pre-Commit:** Add the appropriate linter/formatter to `.pre-commit-config.yaml`.
+    - **Python:** Use `ruff` and `black`.
+    - **Bash:** `shellcheck` is already configured.
+    - **JavaScript/TypeScript:** Use `prettier` and `eslint`.
+2.  **Add Test Scaffolding:** Create a new directory under `tests/unit/` for the language.
+3.  **Add a Test File:** Implement a basic smoke test for the new script, including at least one edge case test.
+4.  **Update CI:** Add a new job to `.github/workflows/ci.yml` to run the tests for the new language.
+
+By following these rules, you will help maintain the quality, consistency, and security of this repository.

+As a repository valued by QA, we expect a rigorous, test-focused mentality. Every script should be developed with the assumption that it will be scrutinized for robustness and reliability.

+### Guiding Principles
+- **Write Tests First (or alongside):** Don't write code without a clear idea of how you will test it.
+- **Think Like an Attacker (and a User):** Consider how your script could be misused, intentionally or accidentally.
+- **Automate Everything:** All tests should be runnable from the command line and in CI.
+- **Keep Scripts Standalone:** Scripts must remain self-contained and runnable without the test framework. Test files are external and should import or execute the script to be tested.

+### Test Coverage Checklist
+Before submitting, ensure your tests cover the following scenarios:
+
+- [ ] **Happy Path:** Does the script work as expected with valid, typical inputs?
+- [ ] **Invalid Inputs:** How does the script handle incorrect, malformed, or unexpected inputs? (e.g., wrong data types, non-existent files).
+- [ ] **Edge Cases:**
+    - [ ] Empty or null inputs.
+    - [ ] Very large inputs (e.g., large files, many items).
+    - [ ] Zero-value inputs (e.g., `0`, `""`).
+    - [ ] Inputs with special characters or different encodings.
+- [ ] **Permissions:** Does the script fail gracefully if it lacks the required permissions for a file, directory, or network resource?
+- [ ] **Dependencies:** How does the script behave if a required dependency (module, command-line tool) is missing?
+- [ ] **Concurrency:** If applicable, is the script safe to run multiple times simultaneously? Does it handle file locking?

+# Testing Guide
+
+This document outlines the testing framework for the `Scripts` repository.
+
+## Local Testing
+
+### 1. Pre-Commit Hooks (Linting & Formatting)
+
+This repository uses `pre-commit` to run a suite of linters and formatters before each commit.
+
+**Installation:**
+
+1. Install Python 3.9+ and pip.
+2. Install `pre-commit`:
+
+   ```bash
+   pip install pre-commit
+   ```
+
+3. Set up the git hooks:
+
+   ```bash
+   pre-commit install
+   ```
+
+**Usage:**
+
+The hooks will run automatically on `git commit`. To run them manually across all files:
+
+```bash
+pre-commit run --all-files
+```
+
+### 2. PowerShell Unit Tests
+
+PowerShell tests are written using the **Pester** framework.
+
+**Prerequisites:**
+
+*   PowerShell 7+
+*   Pester module
+
+**Installation (from PowerShell):**
+
+```powershell
+Install-Module -Name Pester -Force -SkipPublisherCheck
+```
+
+**Running Tests:**
+
+To run all PowerShell unit tests:
+
+```powershell
+Invoke-Pester -Path 'tests/unit/PowerShell'
+```
+
+## Continuous Integration (CI)
+
+The CI pipeline is defined in `.github/workflows/ci.yml` and runs automatically on pushes and pull requests to the
+`main` branch.
+
+It performs two main jobs:
+
+1. **`lint`**: Runs all `pre-commit` hooks on an Ubuntu runner.
+2. **`test-powershell`**: Runs all Pester tests on a Windows runner.

 configuration

- Changed psscriptanalyzer language from 'powershell' to 'system' in .pre-commit-config.yaml
- Fixed bash syntax error in template.sh (replaced 'else {' with 'else')
- Fixed SC2155 ShellCheck warnings by separating variable declarations and assignments
- Updated markdownlint config to exclude instruction files and be more lenient
- Fixed line length issues in CONTRIBUTING.md
- Added shellcheck disable comment for intentional SCRIPT_DIR in template
- All pre-commit hooks now pass successfully

 ### Guiding Principles
 - **Write Tests First (or alongside):** Don't write code without a clear idea of how you will test it.
 - **Think Like an Attacker (and a User):** Consider how your script could be misused, intentionally or accidentally.
