Automated testing

[lbbrhzn]

We should improve automated testing.
There are some automated tests defined that I took from an example project, but these currently fail.

Some somple tests we should add:

• test configFlows and optionFlow

A more complicated test:

• add a Charge Point simulator, verify that our CentralSystem / ChargePoint implementation can connect with it

Some progress made towards fixing automated tests in #61

Further progress in #72 on charge point simulator
