[Pyunit-interest] passing arguments to TestCase constructor through makeSuite

[Andrew W. <ci...@gw...>]

In my application, I'm passing some contextual information into my TestCase
constructor with a couple of extra arguments.  (I'm using Zope, and the
request information is passed in to me as an argument).  This is easy
enough to do, but the makeSuite function only calls the constructor with
the method name.  Here is my extension to makeSuite() that I'm using to
allow me to pass through my necessary extra arguments.


def makeSuite(testCaseClass, prefix='test', sortUsing=cmp, arguments=()):
    """Returns a TestSuite instance built from all of the test functions
       in the given test case class whose names begin with the given
       prefix. The cases are sorted by their function names
       using the supplied comparison function, which defaults to 'cmp'.

       The test case class constructor is called with the method name,
       and any extra arguments passed in 'arguments'.
    """
    cases = map(lambda methodName, testCaseClass=testCaseClass,
arguments=arguments:
                apply(testCaseClass, (methodName,) + arguments),
                getTestCaseNames(testCaseClass, prefix, sortUsing))
    return TestSuite(cases)
