I tried:

describe DistanceMatrix, "when mocking ..." do
  it "should do call form_matrix" do

    DistanceMatrix.any_instance.stubs(:form_matrix)
    DistanceMatrix.any_instance.should_receive(:get_data_from_yaml).with("file_name.yml")
    DistanceMatrix.new("file_name.yml")

  end
end

but got failure:

Failures:
  1) DistanceMatrix when mocking ... should do call form_matrix
     Failure/Error:
DistanceMatrix.any_instance.should_receive(:get_data_from_yaml).with("file_name.yml")
     (#<Mocha::ClassMethods::AnyInstance:0xa153e48>).get_data_from_yaml("file_name.yml")
         expected: 1 time
         received: 0 times
     # ./tsp_algorithm_spec.rb:275:in `block (2 levels) in <top
(required)>'

Finished in 0.32959 seconds

Also both methods (get_data_from_yaml and get_data_from_db) return Array
