.SYNOPSIS
    Validate MECM/ConfigMgr site systems and configuration.
.DESCRIPTION
    Validate MECM/ConfigMgr site systems operational health status, and recommended configuration.
.PARAMETER SiteCode
    ConfigMgr 3-character alphanumeric site code.
.PARAMETER Database
    Name of site SQL database.
.PARAMETER SiteServer
    NetBIOS or FQDN of site server (primary, CAS, secondary). Default is localhost
.PARAMETER SqlInstance
    NetBIOS or FQDN of site database SQL instance. Default is localhost
.PARAMETER TestingScope
    Scope of tests to execute: All (default), Host, AD, SQL, CM, WSUS, Select
    The Select option displays a gridview to select the individual tests to perform
.PARAMETER ConfigFile
    Path to cmhealth.json (create or import). If not found, it will attempt to create a new
    one in the specified path. The default path is the userprofile\desktop folder.
.PARAMETER Remediate
    Attempt remediation when possible
.PARAMETER Source
    Alternate source path for WinSXS referencing. Used only for Test-HostServerFeatures
    Default is C:\Windows\WinSxS
.PARAMETER DaysBack
    Number of days to go back for checking status messages, errors, warnings, etc. Default is 7
.PARAMETER Credential
    PS Credential object for authenticating under alternate context
.EXAMPLE
    Test-CmHealth -SiteCode "P01" -Database "CM_P01"
    Runs all tests on the local machine using the current user credentials
.EXAMPLE
    Test-CmHealth -SiteCode "P01" -Database "CM_P01" -SiteServer "CM01" -SqlInstance "CM01" -TestingScope "ALL"
    Runs all tests
.EXAMPLE
    Test-CmHealth -SiteCode "P01" -Database "CM_P01" -SiteServer "CM01" -SqlInstance "CM01" -TestingScope "Host"
    Runs only the site server host tests
.EXAMPLE
    Test-CmHealth -SiteCode "P01" -Database "CM_P01" -SiteServer "CM01" -SqlInstance "CM01" -TestingScope "Host" -Remediate -Credential $cred
    Runs only the site server host tests and attempts to remediate identified deficiences using alternate user credentials
.EXAMPLE
    Test-CmHealth -SiteCode "P01" -Database "CM_P01" -SiteServer "CM01" -SqlInstance "CM01" -TestingScope "Host" -Remediate -Source "\\server3\sources\ws2019\WinSxS"
    Runs only the site server host tests and attempts to remediate identified deficiences with WinSXS source path provided
.EXAMPLE
    $failed = Test-CmHealth -SiteCode "P01" -Database "CM_P01" | Where-Object Status -eq 'Fail'
    Runs all tests and only returns those which failed
.EXAMPLE
    Test-CmHealth -SiteCode "P01" -Database "CM_P01" | Select-Object TestName,Status,Message | Where-Object Status -eq 'Fail'
    Display summary of failed tests
.EXAMPLE
    $results = Test-CmHealth -SiteCode "P01" -Database "CM_P01" | Where-Object Status -eq 'Fail'; $results | Select TestData
    Display test output from failed tests
.EXAMPLE
    $results = Test-CmHealth -SiteCode "P01" -Database "CM_P01" -TestScope Previous
    Run the same set of tests as the previous session (each run saves list of test names)
