IndexOf 存在问题

示例代码： go func getSampleData() []*user { return []*user{ { id: 1, name: "test 1", }, { id: 2, name: "test 2", }, { id: 3, name: "test 3", }, { id: 4, name: "test 4", }, { id: 5, name: "test 5", }, } } func TestFind(t *testing.T) { userList := arraylist.New(getSampleData()) index := userList.IndexOf(&user{ id: 1, name: "test 1", }) if index == -1 { t.Fatalf("Array list should not return -1 as a response of find") } }
