🧪 Add test for load_documents empty directory handling#1
Conversation
Implemented a new test file test_createDatabase.py that verifies load_documents correctly handles the case where the DATA_PATH directory does not exist. Changes: - Created test_createDatabase.py - Mocked missing dependencies (langchain, dotenv) to allow imports - Added TestCreateDatabase.test_load_documents_empty_directory_handling - Verified that os.makedirs is called and an empty list is returned when DATA_PATH is missing Co-authored-by: Kshitij-KS <76816193+Kshitij-KS@users.noreply.github.com>

This test mutates sys.modules at import time and never restores it, so when the suite runs in a single Python process, any later test that imports langchain* or dotenv will get MagicMock modules instead of real packages. That can make unrelated tests pass/fail for the wrong reason and hides integration regressions; scope these injections with patch.dict(..., clear=False) or a fixture that cleans up after the test.

🎯 What: The testing gap addressed: Untested load_documents empty directory handling.
📊 Coverage: Tested the scenario where DATA_PATH does not exist.
✨ Result: Increased reliability of the document loading process by ensuring the directory is created and the function handles it gracefully.
