small unit test framework

Some reasons:

- Standard unittest module has flaw with teardown (called only if there
is no error/exception) left for backward compatibility

- Uses awkward conventions for test functions (function should be
started with test prefix) while decorators are more suitable

- There is no standard way in it to perform flexible setup/teardown
combining set of several functions

- It is easier to enhance own framework with needed functionality :)
