"""
Run a validation operator against some data.
There are two modes to run this command:
1. Interactive (good for development):
Specify the name of the validation operator using the --name argument
and the name of the expectation suite using the --suite argument.
The cli will help you specify the batch of data that you want to
validate interactively.
2. Non-interactive (good for production):
Use the `--validation_config_file` argument to specify the path of the validation configuration JSON file. This file can be used to instruct a validation operator to validate multiple batches of data and use multiple expectation suites to validate each batch.
Learn how to create a validation config file here:
https://great-expectations.readthedocs.io/en/latest/command_line.html#great-expectations-validation-operator-run-validation-config-file-validation-config-file-path
This command exits with 0 if the validation operator ran and the "success" attribute in its return object is True. Otherwise, the command exits with 1.
