How to execute custom expectations using v3 API

Archive

Hi all,

I’ve been following this guide: How to create custom Expectations — great_expectations documentation on how to write a custom expectation using and I’ve been able to create a metric and expectation, I don’t know how to invoke it. With the v2 API, this was pretty easy: just run batch.expect… in your notebook.

But with the batch request API, I don’t know how to actually run the custom expectation. Executing the constructor for it just results in some errors.

Any help would be appreciated

Make sure that you import the class of your new custom expectation. Then follow the V3 guides for using any expectations. Your expectation will be available.
