提供一种通过mock方式的单元测试用例： //solution.go type Solution interface { JudgePalindrome(s string) bool }

type App struct { S Solution }

func (a *App) judgePalindrome(s string) bool { runeS := []rune(strings.ToUpper(s)) start, end := 0, len(runeS)-1 for end > start { if runeS[start] != runeS[end] { return false } end-- start++ } return true } //go:generate mockgen -destination ../mocks/mock_solution.go -package mock -source solution.go

func TestApp_judgePalindrome(t *testing.T) { tests := []struct { name string str string want bool }{ { name: "test ok", str: "abba", want: true, }, { name: "test fail", str: "abc", want: false, },

    {
        name: "中文回文",
        str:  "你好好你",
        want: true,
    },
    {
        name: "中文非回文",
        str:  "思考思考是",
        want: false,
    },
    {
        name: "empty",
        want: true,
        str:  "",
    },
}
for _, tt := range tests {
    t.Run(tt.name, func(t *testing.T) {
        ctrl := gomock.NewController(t)
        defer ctrl.Finish()
        mockSolution := mock.NewMockSolution(ctrl)
        mockSolution.EXPECT().JudgePalindrome(tt.str).AnyTimes().Return(tt.want)
        app := App{S: mockSolution}
        if got := app.judgePalindrome(tt.str); got != tt.want {
            t.Errorf("judgePalindrome() = %v, want %v", got, tt.want)

性能比较测试中，遍历b.N的作用是什么?
