ci_dbt_core_testing.yml

# **what?**
# Runs all tests in dbt-core with this branch of dbt-common to ensure nothing is broken

# **why?**
# Ensure dbt-common changes do not break dbt-core

# **when?**
# This will run when trying to merge a PR into main.
# It can also be manually triggered.

# This workflow can be skipped by adding the "Skip Core Testing" label to the PR.  This is
# useful when making a change in both `dbt-core` and `dbt-common` where the changes are dependant
# and cause the other repository to break.
