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: clockface_acceptance_test.go
    path of file: ./repos/learn-go-with-tests/math/v7c/clockface
    
    the code of the file until where you have to start completion: package clockface_test

import (
	"bytes"
	"encoding/xml"
	"testing"
	"time"

	"github.com/quii/learn-go-with-tests/math/v7c/clockface"
)

type SVG struct {
	XMLName xml.Name `xml:"svg"`
	Text    string   `xml:",chardata"`
	Xmlns   string   `xml:"xmlns,attr"`
	Width   string   `xml:"width,attr"`
	Hei
    
func TestSVGWriterSecondHand(t *testing.T) {
	cases := []struct {
		time time.Time
		line Line
	}{

			simpleTime(0, 0, 0),
			Line{150, 150, 150, 60},
		},
		{
			simpleTime(0, 0, 30),
			Line{150, 150, 150, 240},
		},
	}

	for _, c := range cases {
		t.Run(testName(c.time), func(t *testing.T) {
			b := bytes.Buffer{}
			clockface.SVGWriter(&b, c.time)

			svg := SVG{}
			xml.Unmarshal(b.Bytes(), &svg)
