- class autotransform.validator.base.Validator
Bases:
NamedComponent
The base for Validator components. Validators test that the codebase is still healthy after a transformation.
- name
The name of the component.
- Type:
ClassVar[ValidatorName]
- abstract check(batch: Batch, transform_data: Mapping[str, Any] | None) ValidationResult
Validate that a Batch that has undergone transformation does not produce any issues such as test failures or type errors.
- Parameters:
batch (Batch) – The transformed Batch to validate.
transform_data (Optional[Mapping[str, Any]]) – Data from the transformation.
- Returns:
- The result of the validation check indicating the severity of any
validation failures as well as an associated message.
- Return type:
- model_computed_fields: ClassVar[dict[str, ComputedFieldInfo]] = {}
A dictionary of computed field names and their corresponding ComputedFieldInfo objects.
- model_config: ClassVar[ConfigDict] = {}
Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
- model_fields: ClassVar[dict[str, FieldInfo]] = {}
Metadata about the fields defined on the model, mapping of field names to [FieldInfo][pydantic.fields.FieldInfo].
This replaces Model.__fields__ from Pydantic V1.
