    Test coverage for the AI Models Credentials domain model.

    """

    Background: Common setup
        Given the cleveragents package is available

    Scenario: Import and instantiate ModelProviderOption with all fields
        When I import ModelProviderOption from aimodelscredentials
        Then the ModelProviderOption class should be available
        And I can create a ModelProviderOption with publishers, config, and priority

    Scenario: Create ModelProviderOption with minimal required fields
        When I create a ModelProviderOption with only priority set to 1
        Then the ModelProviderOption should have priority 1
        And the publishers dictionary should be empty
        And the config should be None

    Scenario: Create ModelProviderOption with publishers dictionary
        When I create a ModelProviderOption with complex publishers structure
        Then the publishers field should contain the expected dictionary structure
        And the ModelPublisher enum values should be properly handled

    Scenario: Create ModelProviderOption with ModelProviderConfigSchema
        When I create a ModelProviderOption with a config object
        Then the config field should contain the ModelProviderConfigSchema instance
        And the config should be properly validated

    Scenario: Validate ModelProviderOption strips whitespace
        When I create a ModelProviderOption with strings containing whitespace
        Then the string fields should have whitespace stripped

    Scenario: Validate ModelProviderOption assignment validation
        When I create a ModelProviderOption instance
        And I update its fields with new values
        Then the assignment validation should be triggered
        And the values should be properly validated

    Scenario: Validate ModelProviderOption populate by name
        When I create a ModelProviderOption using field aliases
        Then the fields should be populated correctly by name

    Scenario: Validate ModelProviderOption use enum values
        When I create a ModelProviderOption with ModelPublisher enums
        Then the enum values should be used in serialization
        And the model should handle enum values properly

    Scenario: Test ModelProviderOption field defaults
        When I create a ModelProviderOption with default fields
        Then publishers should default to an empty dictionary
        And config should default to None

    Scenario: Test ModelProviderOption field validation with invalid data
        When I try to create a ModelProviderOption with invalid priority
        Then a ModelProviderOption validation error should be raised
        And the error should indicate the priority field issue

    Scenario: Test ModelProviderOption model config settings
        When I examine the ModelProviderOption model_config
        Then the ModelProviderOption str_strip_whitespace should be True
        And the ModelProviderOption validate_assignment should be True
        And the ModelProviderOption arbitrary_types_allowed should be False
        And the ModelProviderOption populate_by_name should be True
        And the ModelProviderOption use_enum_values should be True

    Scenario: Test ModelProviderOption with nested publisher structures
        When I create a ModelProviderOption with nested publisher dictionaries
        Then the nested structure should be properly maintained
        And the ModelPublisher boolean values should work correctly

    Scenario: Test ModelProviderOption serialization and deserialization
        When I serialize a ModelProviderOption to dict
        And I deserialize it back to ModelProviderOption
        Then the round-trip should preserve all data

    Scenario: Test ModelProviderOption with None config field
        When I explicitly set config to None in ModelProviderOption
        Then the config field should accept None value
        And the model should be valid

    Scenario: Test ModelProviderOption priority field requirement
        When I try to create a ModelProviderOption without priority
        Then a ModelProviderOption validation error should be raised for missing required field
