## Overview

NDA is a Selenium/Pytest UI automation framework for a web-based network-device administration application. Its principal workflow launches a browser, logs in, then exercises device management, software configuration, software updates, and configuration validation; page objects perform UI actions and verify outcomes. The README also describes smoke/regression coverage and report/evidence generation. The fixture-to-login call and page-object behavior are visible in sampled source; links from individual test modules to page objects reflect the documented test/POM structure, not inspected test implementations.

Main entry points: [`pages/software_config_page.py`](https://github.com/kiran112p/nda/blob/main/pages/software_config_page.py) (Software configuration), [`pages/software_update_page_device_paralell.py`](https://github.com/kiran112p/nda/blob/main/pages/software_update_page_device_paralell.py) (Software update), [`pages/validate_config_module.py`](https://github.com/kiran112p/nda/blob/main/pages/validate_config_module.py) (Config validation), [`helpers/locaters.py`](https://github.com/kiran112p/nda/blob/main/helpers/locaters.py) (Locators and values)
