[Insight-developers] ITK Regression tests & 'expected' exceptions

[kent williams]

In an effort to increase coverage on the Code/Review/itkTransform
Reader/Writer, I added some expected exceptions -- like calling Update()
without setting filename, and asking it to read a file with an unrecognized
file extension.

It appears that if there's an exception during testing, it's counted as an
error.  Should it really be an error to test exception handling?
