Unable to Mock the PowerCLI: Get-View command in the code coverage

[vinayakorrapati]

Wrote the powershell script to get ch the cluster and related host information using the:
Get-View -Server $vcenter -ViewType ClusterComputeResource -ErrorAction stop

# Mocking the Connect-VIServer to return a valid mock VIServer object
$mockVIServer = New-Object -TypeName PSObject -Property @{
    Name = "mock-vcenter.local"
    IsConnected = $true
    InstanceUuid = "mock-uuid-1234"
}

# Mock Connect-VIServer to return the mock VIServer object
Mock -CommandName Connect-VIServer -MockWith { 
    return $mockVIServer
}

Mocking the view with:

Mock -CommandName Get-View -MockWith {
    param($Server, $ViewType)

    if ($Server.Name -eq "mock-vcenter.local" -and $ViewType -eq "ClusterComputeResource") {
        # Mocking the cluster and host information
        return @(
            New-Object PSObject -Property @{
                Name = "MockCluster1"
                MoRef = @{ Value = "cluster-123" }
                host = @(@{ Value = "host-1" }, @{ Value = "host-2" })
            }
        )
    }
}

When we execute the test case :
$result = & $newscriptPath -vcenter $vcenter -VCenterCreds $mockVCenterCreds

Facing the below issue:

Cannot process argument transformation on parameter 'Server'. Cannot convert the "mock-vcenter.local" value of type "System.String" to type "VMware.VimAutomation.ViCore.Types.V1.VIServer[]".

Tried multiple ways. KIndly give the suggestions to fix this issue.

The mocked $vcenter isn't created as a VIServer object. If you can't create a real VIServer-object, try disabling the type check in your Get-View mock using Mock -CommandName Get-View -RemoveParameterType Server -MockWith ....
