################################################################################
<#
.SYNOPSIS
Executesunit tests for GenXdev modules, sub-modules, or cmdlets
with intelligent debugging and AI-powered error resolution.
 
.DESCRIPTION
This function provides a testing framework for GenXdev modules,
offering multi-level test execution from entire modules down to individual
cmdlets. It integrates PSScriptAnalyzer for static code analysis, Pester for
unit testing, and Get-Help validation for documentation compliance. The
function includes intelligent error handling with AI-powered resolution
capabilities and detailed progress reporting for development workflows.
 
.PARAMETER CmdletName
Search pattern to filter cmdlets for testing. Supports wildcards and allows
targeting specific cmdlets or groups of cmdlets matching the pattern.
 
.PARAMETER DefinitionMatches
Regular expression to match cmdlet definitions during the search process.
This allows for advanced filtering based on cmdlet implementation patterns.
 
.PARAMETER ModuleName
GenXdev module names to search and test. Must follow the pattern starting
with 'GenXdev' followed by optional sub-module components. Supports wildcards
for broad module selection.
 
.PARAMETER NoLocal
Skip searching in local module paths during cmdlet discovery. When specified,
only published module paths will be considered for testing.
 
.PARAMETER OnlyPublished
Limit search to published module paths only. This excludes local development
modules and focuses on officially published GenXdev modules.
 
.PARAMETER FromScripts
Search in script files instead of module files. This allows testing of
standalone PowerShell scripts within the GenXdev ecosystem.
 
.PARAMETER IncludeScripts
Include the scripts directory in addition to regular modules. This expands
the test scope to cover both modular and script-based functionality.
 
.PARAMETER OnlyReturnModuleNames
Return only unique module names instead of full cmdlet details. Useful for
discovery and inventory operations rather than detailed testing.
 
.PARAMETER ExactMatch
Require exact matches for cmdlet names rather than wildcard matching. This
provides precise targeting for specific cmdlet testing scenarios.
 
.PARAMETER Verbosity
Output detail level for test execution. Controls the amount of information
displayed during test runs, from minimal to diagnostic output.
 
.PARAMETER StackTraceVerbosity
Stack trace detail level for error reporting. Determines how much call stack
information is included when errors occur during testing.
 
.PARAMETER TestFailedAction
Action to take when a test fails. Options include interactive prompting,
automatic continuation, stopping execution, AI-powered resolution, error
logging, or exception throwing for integration scenarios.
 
.PARAMETER AllowLongRunningTests
Include unit tests that have long running durations in the test execution.
This enables testing including performance and integration tests.
 
.PARAMETER SkipModuleImports
Skip importing GenXdev modules before testing. This is useful when modules
are already loaded or when testing specific module loading scenarios.
 
.PARAMETER SkipPSAnalyzerTests
Skip invoking PSScriptAnalyzer tests during the test execution. This allows
focusing solely on functional testing when static analysis is not required.
 
.PARAMETER SkipPesterTests
Skip invoking Pester tests during the test execution. This allows focusing
solely on static analysis when functional testing is not required.
 
.EXAMPLE
Assert-GenXdevTest -ModuleName "GenXdev.AI"
Executes all tests for the GenXdev.AI module including PSScriptAnalyzer and
Pester tests.
 
.EXAMPLE
Assert-GenXdevTest -SubModuleName "GenXdev.Coding.PowerShell.Modules" `
    -TestFailedAction SolveWithAI
Tests the specified sub-module and uses AI to automatically resolve any
failures encountered during testing.
 
.EXAMPLE
Assert-GenXdevTest -CmdletName "Get-GenXDevCmdlet" -Verbosity Detailed
Tests the specific cmdlet with detailed output showing all test operations
and results.
 
.EXAMPLE
testcmdlet Assert-GenXdevTest
Uses the alias to test the current cmdlet with default settings.
