potiuk opened a new pull request, #41004:
URL: https://github.com/apache/airflow/pull/41004
Introduce a possibility to run tests in "DB isolation" mode.
Such tests will require an internal-api component to be running alongside
the tests and some specific configuration that will be shared via environment
variables.
This one adds support for breeze testing tests command and for the
interactive breeze shell command.
It already works for most tests in dag_processor - with few caveats to fix.
It is not yet wired to the CI but it should be a very easy special test case
to add - once we get the tests "green".
The gist of it is to make sure that when the
`RUN_TESTS_WITH_DATABASE_ISOLATION` environment variable is set to `true`,
there is a special TracebackSesssionForTests created that will allow test code
to run DB operations (setip/teardown and initialization in tests while it will
not allow "airflow" code to create a DB session (it will raise exception) and
all the airflow code should use internal_api in this case.
