◆ checkBasicSimplify()
def astshim.test.MappingTestCase.checkBasicSimplify |
( |
|
self, |
|
|
|
amap |
|
) |
| |
Check basic simplfication for a reversible mapping
Check the following:
- A compound mapping of a amap and its inverse simplifies to
a unit amap.
- A compound mapping of a amap and a unit amap simplifies to
the original amap.

◆ checkMappingPersistence()

( |
|
self, |
|
|
|
amap, |
|
|
|
poslist |
|
) |
| |
Check that a mapping gives identical answers to unpersisted copy
poslist is a list of input position for a forward transform
(if it exists), or the inverse transform (if not).
A numpy array with shape [nAxes, num points]
or collection that can be cast to same
Checks each direction, if present. However, for generality,
does not check that the two directions are inverses of each other;
call checkRoundTrip for that.
Does everything checkPersistence does, so no need to call both.

◆ checkMemoryForCompoundObject()

obj1, |
|
|
|
obj2, |

cmpObj, |
|
|
|
isSeries |
|
) |
| |
Check the memory usage for a compoundObject
obj1: first object in compound object
obj2: second object in compound object
cmpObj: compound object (SeriesMap, ParallelMap, CmpMap or CmpFrame)
isSeries: is compound object in series? None to not test
(e.g. CmpFrame)

◆ checkRoundTrip()

rtol = 1e-05 , |
|
|
|
atol = 1e-08 |
|
) |
| |
Check that a mapping's reverse transform is the opposite of forward
amap is the mapping to test
poslist is a list of input position for a forward transform;
a numpy array with shape [nin, num points]
or collection that can be cast to same
rtol is the relative tolerance for numpy.testing.assert_allclose
atol is the absolute tolerance for numpy.testing.assert_allclose
