iodata.test.test_fchk module

Test iodata.formats.fchk module.

check_load_azirine(key, numbers)

Perform some basic checks on a azirine fchk file.

check_load_dump_consistency(tmpdir, fn, match=None)

Check if dumping and loading an FCHK file results in the same data.

Parameters:

• tmpdir (str) – The temporary directory to dump and load the file.

• fn (str) – The filename to load.

• match (Optional[str]) – When given, loading the file is expected to raise a warning whose message string contains match.

check_load_nitrogen(key, numbers, numbers_spin)

Perform some basic checks on a nitrogen fchk file.

check_normalization_dm_azirine(key)

Perform some basic checks on a 2h-azirine fchk file.

check_trj_basics(trj, nsteps, title, irc)

Check sizes of arrays, step and point attributes.

load_fchk_helper(fn_fchk)

Load a testing fchk file with iodata.iodata.load_one.

load_fchk_trj_helper(fn_fchk)

Load a trajectory from a testing fchk file with iodata.iodata.load_many.
