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.

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.
