ExpectColumnValuesToMatchLikePattern
(configuration: Optional[ExpectationConfiguration] = None)¶ Bases:
great_expectations.expectations.expectation.ColumnMapExpectation
Base class for all Expectations.
- Expectation classes must have the following attributes set:
domain_keys: a tuple of the keys used to determine the domain of the expectation
success_keys: a tuple of the keys used to determine the success of the expectation.
In some cases, subclasses of Expectation (such as TableExpectation) can inherit these properties from their parent class.
They may optionally override runtime_keys and default_kwarg_values, and may optionally set an explicit value for expectation_type.
runtime_keys lists the keys that can be used to control output but will not affect the actual success value of the expectation (such as result_format).
default_kwarg_values is a dictionary that will be used to fill unspecified kwargs from the Expectation Configuration.
- Expectation classes must implement the following:
_validate
get_validation_dependencies
In some cases, subclasses of Expectation, such as ColumnMapExpectation will already have correct implementations that may simply be inherited.
- Additionally, they may provide implementations of:
validate_configuration, which should raise an error if the configuration will not be usable for the Expectation
