General info
============
The unit tests
--------------
shFlags is designed to work on as many environments as possible, but not all
environments are created equal. As such, not all of the unit tests will succeed
on every platform. The unit tests are therefore designed to fail, indicating to
the tester that the supported functionality is not present, but an additional
test is present to verify that shFlags properly caught the limitation and
presented the user with an appropriate error message.
shFlags tries to support both the standard and enhanced versions of ``getopt``.
As each responds differently, and not everything is supported on the standard
version, some unit tests will be skipped (i.e. ASSERTS will not be thrown) when
the standard version of ``getopt`` is detected. The reason being that there is
no point testing for functionality that is positively known not to exist. A
tally of skipped tests will be kept for later reference.
Standard vs Enhanced getopt
---------------------------
Here is a matrix of the supported features of the various **getopt** variants.
+=========================================+=====+=====+
| Feature | std | enh |
+-----------------------------------------+-----+-----+
| short option names | Y | Y |
| long option names | N | Y |
| spaces in string options | N | Y |
| intermixing of flag and non-flag values | N | Y |
+=========================================+=====+=====+
Known Issues
------------
The **getopt** version provided by default with all versions of Mac OS X (up to
and including 10.5.6) and Solaris (up to and including Solaris 10 and
OpenSolaris) is the standard version.
Workarounds
-----------
The Zsh shell requires the ``shwordsplit`` option to be set and the special
``FLAGS_PARENT`` variable must be defined. See ``src/shflags_test_helpers`` to
see how the unit tests do this.
