    <#

        .SYNOPSIS

            Converts Pester results and exports file in required format for launching the Power BI command. **You will need refresh* the Power BI dashboard every time to see the new results.

        .DESCRIPTION

            Converts Pester results and exports file in required format for launching the Power BI command. **You will need refresh* the Power BI dashboard every time to see the new results.

            Basically does this:

                $InputObject.TestResult | Select-Object -First 20 | ConvertTo-Json -Depth 3 | Out-File "$env:windir\temp\dbachecks.json"

        .PARAMETER InputObject

            Required. Resultset from Invoke-DbcCheck. If InputObject is not provided, it will be generated using a very generic resultset:

            Invoke-DbcCheck -Show Summary -PassThru

        .PARAMETER Path

            The directory to store your JSON files. "C:\windows\temp\dbachecks\*.json" by default

        .PARAMETER Environment

            Tag your JSON filename with an enviornment

        .PARAMETER Append

            Don't delete previous default data sources.

        .PARAMETER Force

            Delete all json files in the data source folder.

        .PARAMETER EnableException

            By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

            This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.

            Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

        .EXAMPLE

            Invoke-DbcCheck -SqlInstance sql2017 -Tag identity -Show Summary -PassThru | Update-DbcPowerBiDataSource

            Runs backup tests against sql2017 then saves to json to "$env:windir\temp\dbachecks\dbachecks_identity.json"

        .EXAMPLE

            Invoke-DbcCheck -SqlInstance sql2017 -Tag identity -Show Summary -PassThru | Update-DbcPowerBiDataSource

            Runs backup tests against sql2017 then saves to json to "$env:windir\temp\dbachecks\dbachecks_identity.json"

        .EXAMPLE

            Invoke-DbcCheck -SqlInstance sql2017 -Tag Backup -Show Summary -PassThru | Update-DbcPowerBiDataSource -Path \\nas\projects\dbachecks.json

            Start-DbcPowerBi -Path \\nas\projects\dbachecks.json

            Runs tests, saves to json to \\nas\projects\dbachecks.json but then you'll have to change your data source in Power BI because by default it points to C:\Windows\Temp (limitation of Power BI)
