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

[Luis Ibanez]

BTW,

We have added a set of convenience macros in the file

    Insight/Testing/Code/Review/itkTestingMacros.h

a couple of which are intended to make easier to exercise
exceptions code.

They are:

    TRY_EXPECT_EXCEPTION( ... command ... )

    TRY_EXPECT_NO_EXCEPTION( ... command ... )


The usage will be something like:

    TRY_EXPECT_EXCEPTION(   reader->Update()   );

    TRY_EXPECT_NO_EXCEPTION(  filter->Update)()  );


Note that the argument should be rather simple expressions.

This should make easier to exercise code that may
throw exceptions.

So far we use this only in the Testing/Code/Review
directory.  Once the MACROS mature, it may be a good
idea to move them to a more central directory, so they
can be used by all the standard tests.


       Luis
