feat: add smoke testing test cases

[Priyanka-Microsoft]

Purpose

• ...
  This pull request introduces several improvements and new test utilities to the end-to-end (E2E) test suite, focusing on both backend validation and UI automation for chat and dashboard features. The most significant updates include the addition of a comprehensive KMGenericPage for dashboard testing, enhanced chat interaction methods in HomePage.py, and various reliability improvements for test execution timing.

New Dashboard Test Utilities:

• Added a new file KMGenericPage.py with methods for validating dashboard UI elements, updating and applying filters, verifying blur and chart updates, and toggling dashboard/chat visibility. This enables robust automated testing of dashboard features.

Enhanced Chat Test Automation:

• Introduced multiple utility methods in HomePage.py for chat thread management: validate_chat_response (validates chat responses and charts), delete_first_chat_thread, edit_chat_title, and create_new_chat, improving coverage and reliability of chat feature tests.

Test Reliability and Timing Improvements:

• Increased wait times in several places (e.g., after sending chat questions and waiting for responses) to reduce flakiness and accommodate slower backend responses. [1] [2] [3]
• Added timing measurement and logging in backend validation to monitor response durations and improve test diagnostics.

General Code Quality Enhancements:

• Added logging and assertion checks throughout the new and updated methods to improve traceability and error reporting in test runs. [1] [2]
• Minor cleanups and import additions for consistency and expanded functionality. [1] [2]
