 # dbt-testing-examples
 
 This repository contains examples of how to implement real unit tests for a dbt data application by using the [dbt-unit-testing](https://github.com/EqualExperts/dbt-unit-testing) package. You can also check the articles I wrote on testing data pipelines and data products with dbt
