[bats](https://bats-core.readthedocs.io/en/stable/index.html) is used for testing. To test the image and commands bats and docker are required. Use the following commands to run all of the tests.

All tests are kept in `tests/` and all of the extension `.bats`. `test_functions.bash` is also loaded by each test. The functions include a setup and teardown (see bats docs) which creates and destroys a postgres target server.

Using bats setup and teardown and avoiding exposing postgres ports etc should allow tests to be run in parallel.
