Add lalsimulation waveform-generation python tests

Duncan Macleodrequested to merge
duncanmmacleod/lalsuite:lalsimulation-python-waveform-tests into master

Description

This patch adds test_waveform_generation.py to /lalsimulation/test/python, which attempts to generate a waveform for every approximant using one or more of the XLALSimInspiralTD, XLALSimInspiralFD, XLALSimInspiralChooseTDWaveform, and XLALSimInspiralChooseFDWaveform.

The approximants are handled in parametrised groups, the idea being to sanity check the code by generating a non-zero waveform, and not test much else. All tests run with zero spin, and zero eccentricity, with the following exceptions:

  • HGImri has s1z = 0.6
  • EccentricFD and EccentricTD have ecc = 0.1

Additionally, because the CI doesn't have access to lalsuite-extra, or lvcnr-lfs, approximants requiring external data are skipped.

ATOW, the following cases are failing:

Approximant Function(s) m1,m2 Error
HGimri SimInspiralFD 40,4 XLAL Error: Radius is negative or NaN. Failed to complete 10 steps inside light ring. Use smaller time step dt. Halting FINALPLUNGE.
IMRPhenomC SimInspiralChooseTDWaveform, SImInspiralTD 10,10 XLAL Error - IMRPhenomCGenerateFDForTD (LALSimIMRPhenomC.c:456): The required length passed as input wont fit the FD waveform
PhenSpinTaylor SimInspiralChooseTDWaveform, SimInspiralTD, SimInspiralFD 10,10 Segmentation fault
PhenSpinTaylorRD SimInspiralChooseTDWaveform, SimInspiralTD, SimInspiralFD 10,10 Segmentation fault
SpinTaylorF2 SimInspiralTD, SimInspiralChooseFDWaveform, SimInspiralFD 10,10 abs(hp + hc) is identically zero
SpinTaylorT4Fourier SimInspiralChooseFDWaveform, SimInspiralTD, SimInspiralFD 10,10 XLAL Error - XLALSimInspiralSpinTaylorDriverFourier: spline interpolation returned with error code 4
SpinTaylorT5Fourier SimInspiralTD 10,10 Segmentation fault
SpinTaylorT5Fourier SimInspiralChooseFDWaveform, SimInspiralFD 10,10 XLAL Error - XLALSimInspiralSpinTaylorDriverFourier: spline interpolation returned with error code 4
TaylorT3 SimInspiralChooseTDWaveform 1.4,1.4 XLAL Error - XLALSimInspiralTofV (LALSimInspiralTaylorLength.c:127): Internal function call failed

I am happy to be told that the input parameters are wrong for one or more of these tests.
