.SYNOPSIS
Comprehensive OAuth2 authentication test script for WS1API module.

.DESCRIPTION
Tests OAuth2 functionality including:
- Token URL mapping for different data centers
- OAuth token retrieval with various configurations
- Get-ServerAuth with OAuth2 auth method
- Token format validation
- Error handling
- TokenUrl parameter override

.NOTES
Some tests require valid OAuth credentials to fully execute.
Tests with invalid credentials demonstrate proper error handling.
