    class MyTestClass
      def cucu
        tra(1)
        tra(2)
      end

      def tra(args)

      end
    end

    it "expect on the second", :focus do
      ob = MyTestClass.new
      expect(ob).to receive(:tra).with(2)
      ob.cucu
    end

The best I can think of is this:

expect(ob).to receive(:tra).ordered
expect(obj).to receive(:tra).with(2).ordered

Expectations have to be evaluated in order. If you do the above it will catch the first call to tra regardless of the args and then expect another call to tra with 2 as the arg.

Not sure if you'll see this, but if you do, you can create a "catch-all":

it "expect on the second", :focus do
  ob = MyTestClass.new

  allow(ob).to receive(:tra)  # catch all

  expect(ob).to receive(:tra).with(2)
  ob.cucu
end
