Re-using Old Test Code with PyUnit
Some users will find that they have existing test code that they would
like
to run from PyUnit, without converting every old test function to a
TestCase subclass.
For this reason, PyUnit provides a FunctionTestCase
class. This
subclass of TestCase can be used to wrap an existing test function.
Set-up and tear-down functions can also optionally be wrapped.
Given the following test function:
def testSomething():
something = makeSomething()
assert something.name is not None
...
one can create an equivalent test case instance as follows:
testcase = unittest.FunctionTestCase(testSomething)
If there are additional set-up and tear-down methods that should be called as
part of the test case's operation, they can also be provided:
testcase = unittest.FunctionTestCase(testSomething,
setUp=makeSomethingDB,
tearDown=deleteSomethingDB)
