Timothy Messier e2248c1360 fix(wh): Associate session fact with credential dimensions (#2787)
The wh_upsert_credential_group function was incorrectly attempting to
update the session connection fact table. There are a couple problems
with this:

1. At the time that this runs, there would be no session connection facts
   for this session.
2. This function is meant to update the session fact table, there is a
   separate function that associates the credential group with the
   session connection facts.

This also fixes another bug that was causing expired rows of the
credential dimension to be included in the group membership. And finally
it fixes a typo in the function name.

SQL Tests

This test suite is used to test behavior of the database logic. In particular the data warehouse implementation is completely in sql via plpgsql, functions, and triggers. This test suite is also implemented directly in sql.

Organization

  • initdb.d: contains init scripts/sql that is run on the test database when it starts. It ensures the sql migrations are run and creates test helper functions.
  • tests: contains the tests. Each file can contain only a single test that runs in a transaction so it can rollback.

The tests leverage the pgTap postgres extension to make assertions and provide more readable test output.

Usage

To run the test run make or make test. This will:

  • Start a docker postgres container and initialize it.
  • Start a docker pgtap container to execute the tests.

When writing new tests it can be faster to keep the database up and just re-run the tests. This can be done by running:

# starts database docker image in the background
make database-up

# runs the tests, call this multiple times while implementing new tests.
make run-tests

# to clean up
make clean

You can also run individual tests:

# run a single test file
make TESTS=tests/setup/wtt_load.sql

# run a single test file with the database already created.
make run-tests TESTS=tests/setup/wtt_load.sql

# run a directory of tests
make TESTS=tests/setup/*.sql

You can pass through options to pg_prove. See the docs for available options, i.e:

# run tests in parallel with verbose output
make PROVE_OPTS='-j9 -v'

By default the database docker container does not use a host port. This can be changed using an environment variable:

$ export SQL_TEST_DB_PORT=5433
$ make database-up
$ make run-tests

Different versions of postgres can easily be tested:

make PG_DOCKER_TAG=latest
make PG_DOCKER_TAG=13-alpine
make PG_DOCKER_TAG=12-alpine
make PG_DOCKER_TAG=11-alpine
