The README in the test directory doesn't contain any hints on what is needed to run the tests:
- What database users do we need
- What passwords can we use
- Can we override the default config

I think the tests should either honor settings in the environment or have a small (optional, not checked into a version control system) config file.

The test *used to* honor the settings RDBMS_USER and RDBMS_PASSWORD in the environment. They no longer seem to do this. Note that having the password in an environment variable constitutes a security risk. But it is still much better than requiring a hard-coded password in the source.

In addition in Postgres when I do have a database user 'rounduptest' most tests run for me.
But a lot of tests seem to use a username 'rounduptest_schema' with an unknown/undocumented password. I'm currently not able to make these tests run.
