pip install tox

Run unit tests:

tox -e unit

Integration tests

At this time, an AWS account is not provided in order to run the tests in CI. We kindly ask contributors/reviewers to use their own AWS accounts in order to test contributions.

You can also reach out in the Slack #athena channel for someone to run the tests for you.

Steps:

Clone the dbt-integration-tests repository

git clone --branch athena-support https://github.com/EarnestResearch/dbt-integration-tests.git

Run the tests:

Additionally, you might need to set the AWS_PROFILE environment variable if you use another value than "default" (for example if you connect to multiple AWS accounts or assume different IAM roles)

AWS_DEFAULT_REGION=us-west-2 ATHENA_S3_STAGING_DIR=s3://dbt-athena-integration-tests/tests/ DBT_PROFILES_DIR=$(pwd)/test/integration/ tox -e integration-athena
