#Requires -Modules Pester

<#
    This pester test verifies the PowerShell module manifest file has valid content that will be required to
    upload to the PowerShell Gallary.
 
    .EXAMPLE
    PS> Invoke-Pester -Script @{Path = '.\src\tests\ModuleManifest.Tests.ps1'; Parameters = @{ ManifestPath = 'C:\Users\zloeber\Dropbox\Zach_Docs\Projects\Git\PSAD'; Author = 'Zachary Loeber'; Website = 'https://github.com/zloeber/PSAD'; Tags = @('ADSI', 'Active_Directory', 'DC') }}
 
    Runs some standard tests and a few manual validations (Tags, Author, and Website).
    .EXAMPLE
    PS> Invoke-Pester -Script @{Path = '.\src\tests\ModuleManifest.Tests.ps1'; Parameters = @{ ManifestPath = '.\PSAD.psd1'}}
 
    Runs several generic tests against the PSAD.psd1 manifest to ensure all required values for uploading to the PowerShell Gallery simply exist.
