To run the integration tests on your local machine, like they will get run in the CI (using CircleCI), you can do the following:

Assuming you are in the integration_tests folder,

make test target=[postgres|redshift|...] [models=...] [seeds=...]

or more specific:

make test target=postgres models=sql.test_star seeds=sql.data_star

or, to test against all targets:

make test-all [models=...] [seeds=...]

Specying models= and seeds= is optional, however if you specify seeds, you have to specify models too.

Where possible, targets are being run in docker containers (this works for Postgres or in the future Spark for example). For managed services like Snowflake, BigQuery and Redshift this is not possible, hence your own configuration for these services has to be provided in the appropriate env files in integration_tests/.env/[TARGET].env

This directory contains an example dbt project which tests the macros in the dbt-utils package. An integration test typically involves making 1) a new seed file 2) a new model file 3) a schema test.

For an example integration tests, check out the tests for the get_url_parameter macro:

1. Macro definition
2. Seed file with fake data
3. Model to test the macro
4. A schema test to assert the macro works as expected

Once you've added all of these files, you should be able to run:

$ dbt deps
$ dbt seed
$ dbt run --model {your_model_name}
$ dbt test --model {your_model_name}

If the tests all pass, then you're good to go! All tests will be run automatically when you create a PR against this repo.
