testTransform()

def lsst.meas.base.tests.TransformTestCase.testTransform (   self,   baseNames = None  )

inherited

Test the transformation on a catalog containing random data.

Parameters
----------
baseNames : iterable of `str`
    Iterable of the initial parts of measurement field names.

Notes
-----
We check that:

- An appropriate exception is raised on an attempt to transform
  between catalogs with different numbers of rows;
- Otherwise, all appropriate conversions are properly appled and that
  flags have been propagated.

The ``baseNames`` argument requires some explanation. This should be
an iterable of the leading parts of the field names for each
measurement; that is, everything that appears before ``_instFlux``,
``_flag``, etc. In the simple case of a single measurement per plugin,
this is simply equal to ``self.name`` (thus measurements are stored as
``self.name + "_instFlux"``, etc). More generally, the developer may
specify whatever iterable they require. For example, to handle
multiple apertures, we could have ``(self.name + "_0", self.name +
"_1", ...)``.
