Mocked Object Properties

Hello Everyone,

Currently when using New-MockObject we get an empty object with no properties set. It seems these properties are read only and aren’t able to be set without overriding the entire property with a note property of the same name. Is this the preferred method for populating the mock object, or is there another way to set these properties that I may be missing?

For reference here is my current code to override the properties:

    $VM = Get-Content .\VirtualMachine.tests.json -Raw | ConvertFrom-Json
    $VMMock = New-MockObject -Type 'Microsoft.Hyperv.PowerShell.VirtualMachine'
    foreach ($property in ($VM | Get-Member -MemberType NoteProperty).Name) { 
        $addmembersplat = @{
            MemberType = [System.Management.Automation.PSMemberTypes]::NoteProperty
            Name = $property
            value = $vm.$property
            Force = $true   
    }

    $VMMock | Add-Member @addmembersplat -ErrorAction 0
    }

Yes. That currently is the only way to populate the properties. I’ve intended to add that functionality to the New-MockObject function for awhile now but just haven’t got to it it. I want to do something like this:

New-MockObject -Type ‘FOO’ -Property @{Name=‘bar’;Type = ‘Property’; Value=‘foo’},@{Name = ‘method1’;Type = ‘Method’; Value = ‘x’}

Thanks for the quick reply, Adam.
