Let the Python function getSample(), exported by ExportToPython, return None instead of a multilayer. Then

$ bin/PyCoreStandardTest HexParaCrystal
Core simulation will be compared with /G/ba/build/tmp/pysuite_HexParaCrystal_out generated by command '/usr/bin/python2.7 /G/ba/build/tmp/pysuite_HexParaCrystal.py'
Traceback (most recent call last):

HexParaCrystal           Interference function of 2D hexagonal pa[SUCCESS]      1.0004e-13

When just running ctest, all this output is overlooked since the test passes.

This indicates two problems, possibly unrelated:
  • The ValueError is somehow catched, and not detected by CTest.
  • A numeric agreement of 1e-13 is found, although the simulation has no chance to return anything but zeros. This is perhaps related with the dubitable definition of almostEqual (#1541)

Resolved in cdc32a6, except for the possible failure to detect zero-filled detector images.

Errors now do appear in the CTest output.
Insensitivity of the tests to empty simulation output cannot be confirmed.
Rather, I was misled by output from roughness simulation, which looks all zero, but is not.
