Improve code coverage
The code coverage of tests should be improved as much as reasonable for the following packages
-
database -
routes/dashboard -
routes/file -
routes/scenario -
routes/signal -
routes/simulationmodel -
routes/simulator -
routes/user -
routes/widget
Especially the testing of error return codes has to be improved. However, testing for a 500 (internal server error) return code due to a database failure will be difficult.
