Backend Tests

[Qqwy]

Here is a list of things we want to test.

Please add any ideas to this list as well.

These can actually be implemented in separate PRs or sub-issues by different people. This issue is to track the overall effort.

Things we test

• User entity (doctests)
• User repository (doctests)
• Dashboard entity (doctests)
• Dashboard repository (doctests)
• Endpoint entity (doctests)
• EndpointCall entity (doctests)
• Aggregator (doctests)
• Aggregator (property tests)
• Task scheduling
• dashboard_fetch: Parsing responses of remote flask-monitoring-dashboard.

Things we explicitly do not test

• the pydash_web API. Makes it easier to change things around i.c.m. with front-end. At some point we might want a couple of regression tests, but these should mostly be covered by front-end integration tests.

• The User Entity, Repository and API now contains a 100% coverage.
• The Dashboard Endity, Repository and API contains quite a bit of coverage.
• The Task Scheduling stuff contains a 98% of coverage (although running the script multiple times might give slightly varying coverage-numbers because most of the scheduling stuff is run in separate OS processes which coverage.py is not able to always pick up properly).
