 `dbt-expectations` is an extension package for [**dbt**](https://github.com/dbt-labs/dbt), inspired by the [Great Expectations package for Python](https://greatexpectations.io/). The intent is to allow dbt users to deploy GE-like tests in their data warehouse directly from dbt, vs having to add another integration with their data warehouse.
