Processing Algorithm tests only test existence of output, not correctness

[koebi]

We only test if an output layer exists, not if it contains something.
Given that we are testing against a live API with regularly changing data, results are bound to change but some assumptions can be made:

• Directions:

  • resulting PolyLine has length > 0

• Isochrones:

  • resulting Polygons have area > 0
  • "outer" Polygon has bigger area than "inner" polygon

• Matrix:

  • distances/durations are > 0

• Export:

  • resulting PolyLine-Layer has Lines
  • resulting Point Layer has Points
