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: shape_test.go
    path of file: ./repos/datastation/runner
    
    the code of the file until where you have to start completion: package runner

import (
	"encoding/json"
	"fmt"
	"os"
	"strings"
	"testing"

	"github.com/stretchr/testify/assert"
)

func Tes
    
func TestShape_Pretty(t *testing.T) {
	tests := []struct {
		data   string
		pretty string
	}{
		{
			`[1, "a"]`,
			`Array of
  Varied of
    number or
    string`,
		},
		{
			`[{"a": 1}, {"a": 2}]`,
			`Array of
  Object of
    a of
      number`,
		},
		{
			`{"a": {"b": 2, "c": {"d": "flubber"}}}`,
			`Object of
  a of
    Object of
      b of
        number
      c of
        Object of
          d of
            string`,
		},
	}
	for _, test := range tests {
		var j any
		err := json.Unmarshal([]byte(test.data), &j)
		assert.Nil(t, err)
		s := GetShape("", j, len(test.data))

		p := s.Pretty("")
		assert.Nil(t, err)
		assert.Equal(t, test.pretty, p)
	}
