You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: survey_test.go
    path of file: ./repos/survey
    
    the code of the file until where you have to start completion: package survey

	// the choices for the test
	choices := core.OptionAnswerList([]string{"choice0", "choice1", "choice2", "choice3", "choice4", "choice5"})

	// section the choices into groups of 3
	pageSize := 2
	// test the second item so that we can verify we are in the middle of the list
	sel := 3

	// compute the page info
	page, idx := paginate(pageSize, choices, sel)

	// we should see the first three options
	assert.Equal(t, choices[2:4], page)
	// with the second index highlighted
	assert.Equal(t, 1, idx)
