Current UnitTests/TestCore/FormFactorTest.h tests mostly trivalities (does get<Param> return <Param> as set in the constructor). The only substantial test is whether F(0) agrees with the volume. We need more substantial tests of the form factor computation:
  • is F(q) continuous at/near the singularities?
  • does F(q) along high-symmetry axes agree with analytical values?

  • Status changed from New to Sprint
  • Assignee set to wuttke

first, repair broken tests related to parameter pool

#2 Updated by wuttke over 4 years ago

  • % Done changed from 0 to 20

Specialization tests implemented.
More tests needed.

#3 Updated by wuttke over 4 years ago

  • Status changed from Sprint to Resolved
  • Target version set to Sprint 31
  • % Done changed from 20 to 100

Done in 6b09bc4.

We are now testing:
  • whether F(0)=V
  • continuity (comparing F(q) for small q with F(0))
  • symmetry under reflections and rotations (selectively, not for all shapes)
  • specialization (e.g. whether a pyramid with alpha=pi/2 behaves like a prism)

And indeed, some inaccuracies and errors were found (tests outcommented, tagged "TODO"). See separate issues.
