.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 Database
    Name of site database. Default is "CM_P01"
.PARAMETER SiteCode
    ConfigMgr site code. Default is "P01"
.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 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 Initialize
    Creates or resets a default configuration file on the current user's Desktop named "cmhealth.json"
.PARAMETER Credential
    PS Credential object for authenticating under alternate context
.EXAMPLE
    Test-CmHealth -Initialize
    Generates a new cmhealth.json configuration file on the user desktop. If the file exists, it will be replaced.
.EXAMPLE
    Test-CmHealth
    Runs all tests on the local machine using the current user credentials
.EXAMPLE
    Test-CmHealth -SiteServer "CM01" -SqlInstance "CM01" -Database "CM_P01" -SiteCode "P01" -TestingScope "ALL"
    Runs all tests
.EXAMPLE
    Test-CmHealth -SiteServer "CM01" -SqlInstance "CM01" -Database "CM_P01" -SiteCode "P01" -TestingScope "Host"
    Runs only the site server host tests
.EXAMPLE
    Test-CmHealth -SiteServer "CM01" -SqlInstance "CM01" -Database "CM_P01" -SiteCode "P01" -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 -SiteServer "CM01" -SqlInstance "CM01" -Database "CM_P01" -SiteCode "P01" -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
    $failed = Test-CmHealth | Where-Object {$_.Status -eq "Fail"}
    Runs all tests and only returns those which failed
