Creating Expectations

Creating expectations involves generating and saving an expectation suite. This reference assumes familiarity with our general philosophy for using expectations outlined in the Expectations feature guide.

Saving expectations

At the end of your exploration, call save_expectation_suite to store all Expectations from your session to your pipeline test files. By default, when you save an expectation suite, only expectations that succeeded on their last run are included in the saved suite.

This is how you always know what to expect from your data.

>> my_df.save_expectation_suite("my_titanic_expectations.json")

For more detail on how to control expectation output, please see Standard arguments for expectations and result_format.
