"""Lightweight testing that remains unittest-compatible.
This module exposes decorators and classes to make lightweight testing possible
in a manner similar to what nose allows, where standalone functions can be
tests. It also provides parametric test support that is vastly easier to use
than nose's for debugging, because if a test fails, the stack under inspection
is that of the test and not that of the test framework.
- An @as_unittest decorator can be used to tag any normal parameter-less
function as a unittest TestCase. Then, both nose and normal unittest will
recognize it as such.
