Learning: In unit test files (tests/[Uu]nit/**/*.[Tt]ests.ps1), when DscResource.Test module dependency is not found during BeforeDiscovery setup, the error message should instruct users to run ".\build.ps1 -Tasks noop" (not "build") because the noop task is designed for quick test environment setup. The build task is more extensive and unnecessary when tests run in a separate process, as the module should already be built before running tests.

Learning: In unit test files (tests/[Uu]nit/**/*.[Tt]ests.ps1), when DscResource.Test module dependency is not found during BeforeDiscovery setup, the error message should instruct users to run ".\build.ps1 -Tasks noop" (not "build") because the noop task is designed for quick test environment setup. The build task is more extensive and unnecessary when tests run in a separate process, as the module should already be built before running tests.

• Localize all strings using string keys; remove any orphaned string keys
• Check DscResource.Common before creating private functions
• Separate reusable logic into private functions
• DSC resources should always be created as class-based resources
• Add unit tests for all commands/functions/resources
• Add integration tests for all public commands and resources

{**/*.ps1,**/*.psm1,**/*.psd1}: # PowerShell Guidelines

Naming

• Use descriptive names (3+ characters, no abbreviations)
• Functions: PascalCase with Verb-Noun format using approved verbs
• Parameters: PascalCase
• Variables: camelCase
• Keywords: lower-case
• Classes: PascalCase
• Include scope for script/global/environment variables: $script:, $global:, $env:

File naming

• Class files: ###.ClassName.ps1 format (e.g. 001.SqlReason.ps1, 004.StartupParameters.ps1)

Formatting

Indentation & Spacing

• Use 4 spaces (no tabs)
• One space around operators: $a = 1 + 2
• One space between type and variable: [String] $name
• One space between keyword and parenthesis: if ($condition)
• No spaces on empty lines
• Try to limit lines to 120 characters

Braces

• Newline before opening brace (except variable assignments)
• One newline after opening brace
• Two newlines after closing brace (one if followed by another brace or continuation)

Quotes

• Use single quotes unless variable expansion is needed: 'text' vs "text $variable"

Arrays

• Single line: @('one', 'two', 'three')
• Multi-line: each element on separate line with proper indentation
• Do not use the unary comma operator (,) in return statements to force
  an array

Hashtables

• Empty: @{}
• Each property on separate line with proper indentation
• Properties: Use PascalCase

Comments

• Single line: # Comment (capitalized, on own line)
• Multi-line: <# Comment #> format (opening and closing brackets on own line), and indent text
• No commented-out code

Comment-based help

• Always add comment-based help to all functions and scripts
• Comment-based help: SYNOPSIS, DESCRIPTION (40+ chars), PARAMETER, EXAMPLE sections before function/class
• Comment-based help indentation: keywords 4 spaces, text 8 spaces
• Include examples for all parameter sets and combinations
• INPUTS: List each pipeline‑accepted type (one per line) with a 1‑line description...
