### Description of the change This adds unittests for the default configuration of our dependencies. ### Benefits We are able to detect changes in upstream Charts for those settings. ### Applicable issues - fixes #409 ### Additional information I merged existing unittests with the new ones for `postgresql-ha` and `postgresql`. However, I decided to not do this for `redis-cluster` and `redis`, because the existing tests[^1] also ensure how the Chart behaves when both redis dependencies are disabled. It didn't felt right to split those files. ### Checklist - [x] Templating unittests are added Signed-off-by: justusbunsi <sk.bunsenbrenner@gmail.com> [^1]: e733287dc2/unittests/config/cache-config.yaml, e733287dc2/unittests/config/queue-config.yaml, e733287dc2/unittests/config/session-config.yaml Reviewed-on: gitea/helm-chart#748 Co-authored-by: justusbunsi <sk.bunsenbrenner@gmail.com> Co-committed-by: justusbunsi <sk.bunsenbrenner@gmail.com>
