def create_mocks(target_methods):

    :param target_methods: a dict to define methods to be patched using mock.

    A key of "target_methods" is a target object whose attribute(s) are
    patched.

    A value of "target_methods" is a list of methods to be patched
    using mock. Each element of the list can be a string or a tuple
    consisting of two strings.

    A string specifies a method name of "target" object to be mocked.
    The decorator create a mock object for the method and the started mock
    can be accessed via 'mock_<method-name>' of the test class.
    For example, in case of::

        @create_mocks({api.nova: ['server_list',
                                  'flavor_list']})

            self.mock_server_list.return_value = ...
            self.mock_flavar_list.side_effect = ...

    you can access the mocked method via "self.mock_server_list"
    inside a test class.

    The tuple version is useful when there are multiple methods with
    a same name are mocked in a single test.
    The format of the tuple is::

        ("<method-name-to-be-mocked>", "<attr-name>")

    The decorator create a mock object for "<method-name-to-be-mocked>"
    and the started mock can be accessed via 'mock_<attr-name>' of
    the test class.

    Example::

        @create_mocks({
            api.nova: [
                'usage_get',
                ('tenant_absolute_limits', 'nova_tenant_absolute_limits'),
