## End-to-end tests
The operator provides reference e2e (end-to-end) tests to ensure various infra parts work smoothly together.
Each e2e execution tests a Postgres operator image built from the current git branch. The test runner starts a [kind](https://kind.sigs.k8s.io/) (local k8s) cluster and Docker container with tests. The k8s API client from within the container connects to the `kind` cluster using the standard Docker `bridge` network.
The tests utilize examples from `/manifests` (ConfigMap is used for the operator configuration) to avoid maintaining yet another set of configuration files. The kind cluster is deleted if tests complete successfully.
End-to-end tests are executed automatically during builds; to invoke them locally use `make e2e-run` from the project's top directory. Run `make e2e-tools e2e-build` to install `kind` and build the tests' image locally before the first run.
End-to-end tests are written in Python and use `flake8` for code quality. Please run flake8 [before submitting a PR](http://flake8.pycqa.org/en/latest/user/using-hooks.html).
## Introduce additional configuration parameters
In the case you want to add functionality to the operator that shall be
