Problem: - super().__init__() was called before setting kwargs parameters - super().__init__() calls _validate_env_var() during initialization - At that point, key_env_var hadn't been set yet from kwargs - So environment variable lookup failed with 'api_key is None' Solution: - Move parameter setting (including key_env_var) BEFORE super().__init__() - This ensures _validate_env_var() can access key_env_var when called - Environment variables are now properly loaded during initialization The test_auth_env_var test now passes, confirming the fix works correctly.

Added DEFAULT_CLASS = "WebSocketGenerator" to enable loading via --model_type websocket without explicit class specification - Follows pattern used in other generator modules (test.py, langchain.py, etc.) Issue 2: Fix instantiation error with name parameter - Changed super().__init__(self.name, config_root) to super().__init__("WebSocket Generator", config_root) - Prevents TypeError: attribute name must be string, not 'type' - Passes hardcoded default name that can be overridden via config/CLI - Aligns with maintainer discussion on name configurability Issue 3: Fix CI test failures caused by langchain import - Moved 'import langchain.llms' from module level to __init__ method - Implements lazy loading to prevent ModuleNotFoundError breaking unrelated tests when langchain is not installed - Resolves all CI failures on Linux, macOS, and Windows platforms - Allows plugin cache to build successfully without optional dependencies Issue 4: Update tests to use proper configuration pattern - Modified 10 test functions to use config_root dictionary pattern instead of direct kwargs (auth_bearer, auth_env_var, format_message*, extract_response*, call_model_integration) - Updated expected name assertion from "WebSocket LLM" to "WebSocket Generator" - Maintains compatibility with garak's configuration system Test Results: - WebSocket-specific tests: 17 passed, 3 skipped -
