PowerView.py Test Module

This test module verifies key functionality of PowerView.py, focusing on parameter propagation 
between class methods and LDAP search functionality.

Key features tested:
1. Propagation of the no_vuln_check parameter to LDAP searches
2. Propagation of the no_cache parameter to LDAP searches
3. Proper handling of formatting flags like -Select and -TableView

The tests use a simplified approach where we:
- Mock the LDAP session and paged_search functionality
- Create a minimal test infrastructure that focuses on parameter propagation
- Track which parameters are passed to the mock LDAP functions
- Verify that user-specified options correctly flow through the code

This approach allows testing without requiring an actual LDAP connection
while ensuring that parameter handling works correctly.
