Maester - PowerShell Commands

Overview

This page lists all the commands available in the Maester PowerShell module.

The Maester PowerShell module is a collection of commands that help you write Pester tests to validate your Microsoft 365 tenant configuration. You can view the Graph API calls for these commands in the Maester GitHub repository's src folder. You can also select the Edit this page link found in the command's documentation to view the source code for the command.
