Add tools to be used in Feature tests

[stefanhahmann]

• Add a class + method to test feature serialization/deserialization (FeatureSerializerTestUtils)

  • Contains a method that saves and reloads a feature to/from disk
  • Contains a method that checks, if the feature projection values are the same for two given projection and one given object.

• Add the yet missing BranchDepthFeatureSerializer

• Add a unit test BranchDepthFeatureSerializerTest that makes use of the new test methods

• Updates + Extensions of FeatureComputerTestUtils

  • Call featureComputerService with forceRecomputeAll flag to increase potential test coverage
  • Reduce cast warnings by using Cast.unchecked()
  • Add new method getFeature() so that features can be retrieved without projection
  • Generify getSpotFeatureProjection() and getBranchSpotFeatureProjection() to getFeatureProjection()

Hello @tinevez, @stefanhahmann wrote some unit tests for feature serialization. The tests indicate that the serializer for the BranchDepthFeature is missing. Is this correct? Did you maybe forget to implement the serializer or is there something else wrong here?

@tinevez Is it correct that the BranchDepthFeatureSerializer was missing in the code?

True! I had forgotten about it.
