Now it is possible to mock not only a function but also a class:
class TestClass(object)
def test_func_a(self, m):
m.register_uri('GET', 'http://test.com', text='data')
...
def test_func_b(self, m)
m.register_uri('GET', 'http://test.com', text='data')
...
This new behavior mimics behavior of `patch` from `mock` library.
Added docs for this new feature.
