resolves #1059
docs dbt-labs/docs.getdbt.com/#

Problem

We want to be able to correctly handle arbitrary configs in tests correctly, for models this is currently done with pre/post_model_hook and for snowflake this is mainly for swapping snowflake_wareshouse values, currently we don't actually recognize this config in during tests. by adding updating dbt-core methods we have opened up the ability to pass these into tests correctly but must make specific modifications in the adapters themselves.

asks:

  1. update for logging
  2. add tests

Solution

we can use AdapterLogger to add loggger.info as we need in the model_hook methods

add a new tests to handle scenarios i.e we update snowflake_warehouse to a invalid warehouse.

Do we want to put these logs behind condition of warehouses being different?

@McKnight-42 I don't think we should add any new logging here. The actual queries being run (select current_warehouse() as warehouse + use warehouse different_warehouse) are already appearing in the logs.

Yes, nicely done - we should expect the dbt test to try using a Snowflake warehouse that doesn't exist (use warehouse DBT_TEST_DOES_NOT_EXIST), where previously it wouldn't, and so it should fail with Object does not exist, or operation cannot be performed.

went ahead and also added a assert to catch if that error message stops showing up.

For the sake of completeness, can we add a positive test case that uses this config option, just to make sure it's setting it? The error message we're getting in the negative test case is pretty general.

I think you just need to define this and the other model in outside of all classes once.

This is just a test I don't think it is a feature.

This is just a test I don't think it is a feature.

currently labeled as such because it ties with the core prs dbt-labs/dbt-core#10258 and dbt-labs/dbt-core#10245 but yeah could possibly just be a under the hood update.
