 ## [Unreleased]
 
 ### Added
+- added unit tests for `Get-FabricWorkspaceUser` function to ensure it works correctly with multiple workspaces both in the pipeline and passed to a parameter.
+- Added unit tests for Aliases for `Get-FabricWorkspaceUser` function to ensure backward compatibility.
 - Added credits for authors to all functions and Unit tests to verify the existence of such tags #89
 
 ### Changed
+- Updated `Get-FabricWorkspaceUser` to support pipeline input for `WorkspaceId` and `WorkspaceName` parameters.
+- Renamed `Get-FabricWorkspaceUsers` to match the singular form
 - Get-FabricSqlDatabase accepts Workspace as a pipeline, handles errors correctly and can filter by name (#117).

+.SYNOPSIS
+Retrieves the user(s) of a workspace.
+
+.DESCRIPTION
+The Get-FabricWorkspaceUser function retrieves the details of the users of a workspace.
+
+.PARAMETER WorkspaceId
+The ID of the workspace. This is a mandatory parameter if Workspace is not provided.
+
+.PARAMETER Workspace
+The workspace object. This normally comes from the Get-FabricWorkspace cmdlet. This is a mandatory parameter if WorkspaceId is not provided.
+
+.EXAMPLE
+Get-FabricWorkspaceUser -WorkspaceId '12345678-1234-1234-1234-123456789012
+
+This example retrieves the users of a workspace of the workspace with the ID '12345678-1234-1234-1234-123456789012'.
+
+.EXAMPLE
+$workspace = Get-FabricWorkspace -WorkspaceName 'prod-workspace'
+$workspace | Get-FabricWorkspaceUser
+
+This example retrieves the users of the prod-workspace workspace by piping the object.
+
+.EXAMPLE
+Get-FabricWorkspaceUser -Workspace (Get-FabricWorkspace -WorkspaceName 'prod-workspace')
+
+This example retrieves the users of the prod-workspace workspace by piping the object.
+
+.EXAMPLE
+Get-FabricWorkspace| Get-FabricWorkspaceUser
+
+This example retrieves the users of all of the workspaces. IMPORTANT: This will not return the workspace name or ID at present.
+
+.EXAMPLE
+Get-FabricWorkspace| Foreach-Object {
+Get-FabricWorkspaceUser -WorkspaceId $_.Id | Select-Object @{Name='WorkspaceName';Expression={$_.displayName;}}, *
+}
+
+This example retrieves the users of all of the workspaces. It will also add the workspace name to the output.
+
+.NOTES
+It supports multiple aliases for backward compatibility.
+The function defines parameters for the workspace ID and workspace object. If the parameter set name is 'WorkspaceId', it retrieves the workspace object. It then makes a GET request to the PowerBI API to retrieve the users of the workspace and returns the 'value' property of the response, which contains the users.
