#Requires -Module Pester

<#
.SYNOPSIS
    Integration tests for Connect-AzureDevOps function with real Azure authentication

.DESCRIPTION
    These tests require actual Azure credentials to be set as environment variables:
    - AZURE_DEVOPS_ORGANIZATION
    - tenantId
    - servicePrincipalId
    - servicePrincipalKey

.NOTES
    Run these tests only when you have valid Azure credentials configured.
    These tests will attempt real Azure authentication.
