Feature: AgentNetwork Initialization and Configuration
  As a developer
  I want AgentNetwork to initialize without config, with config files, handle verbose flags, and raise NotImplementedError for message processing
  So that the network layer can be instantiated and identifies unimplemented methods

  Scenario: Initialize AgentNetwork without config files
    Given I have an AgentNetwork instance
    When I initialize it without config files
    Then the config_manager should be created
    And the agent_factory should be None

  Scenario: Initialize AgentNetwork with config files
    Given I have config files available
    When I initialize AgentNetwork with config files
    Then the config_manager should load the files
    And the config should be validated

  Scenario: Process message through network raises NotImplementedError
    Given I have an initialized AgentNetwork
    When I try to process a message
    Then a NotImplementedError should be raised
    And the error should indicate reactive system not implemented

  Scenario: Process message with context raises NotImplementedError
    Given I have an initialized AgentNetwork
    When I try to process a message with context
    Then a NotImplementedError should be raised
    And the error message should be appropriate

  Scenario: Initialize with verbose flag
    Given I want verbose output
    When I initialize AgentNetwork with verbose flag
    Then the network should be created successfully
    And the verbose flag should be handled
