Unit Testing

The dbt-ga4 package treats each model and macro as a 'unit' of code. If we fix the input to each unit, we can test that we received the expected output. To do this, we use the pytest framework as described here:

You'll need to install pytest, pytest-dotenv and create a .env file with a BIGQUERY_PROJECT key containing the name of your BigQuery project. An 'oauth' connection method is assumed for local development.

Installing pytest & pytest-dotenv can be done using the requirements.txt file. Navigate to the unit_tests folder and run

pip install -r requirements.txt

To run the folder's suite of tests, navigate to the unit_tests folder in the command line and run:

python -m pytest .

To run a specific test:

python -m pytest path/to/test.py
