Convenience method for testing yaml configs.

test_yaml_config is a convenience method for configuring the moving parts of a Great Expectations deployment. It allows you to quickly test out configs for system components, especially Datasources, Checkpoints, and Stores.

For many deployments of Great Expectations, these components (plus Expectations) are the only ones you'll need.

test_yaml_config is mainly intended for use within notebooks and tests.

Data Context

Parameters:

yaml_config – A string containing the yaml config to be tested
name – Optional name of the component to instantiate
class_name – Optional, overridden if provided in the config
runtime_environment – Optional override for config items
pretty_print – Determines whether to print human-readable output
return_mode – Determines what type of object test_yaml_config will return. Valid modes are "instantiated_class" and "report_object"
