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: conflict_test.go
    path of file: ./repos/fac/conflict
    
    the code of the file until where you have to start completion: package conflict

import (
	"reflect"
	"testing"

	"github.com/mkchoi212/fac/color"
	"github.com/mkchoi212/fac/testhelper"
)

var dummyFile = struct {
	lines  []string
	start  int
	middle int
	end    int
	diff3  []int
}{
	lines: []string{
		"<<<<<<< Updated upstream:assets/README.md",
		"brew tap 
    
func TestUpdate(t *testing.T) {
	for _, test := range tests {
		// Read "manually written" lines
		f := File{AbsolutePath: test.path}
		err := f.Read()
		testhelper.Ok(t, err)

		// Ignore files with more than one conflicts
		// to simulate manual edit
		if test.numConflicts > 1 {
			continue
		}

		// Update empty `Conflict`
		c := Conflict{File: &f}
		err = c.Update(f.Lines)

		if test.shouldPass {
			testhelper.Ok(t, err)
		} else {
			testhelper.Assert(t, err != nil, "%s should not have passed", f)
		}
	}
}
