Golang: reflect.DeepEqual returns 意外错误

Golang: reflect.DeepEqual returns unexpected false

我有以下代码和下面的代码测试,由于某种原因,deepEqual 返回 false 并且测试失败。现在,通过阅读关于此的 doco,我希望对于如此简单的事情,它能以正确的方式通过?任何一点将不胜感激。谢谢

// customer.go
type Customer struct {
    customerID int
    domains []string
    names []string
}
func NewCustomer(customerID int, domains []string, names []string) *Customer{
    return &Customer{
        customerID: customerID,
        domains: domains,
        names:names,
    }
}
// customer_test.go
func TestNewCustomer(t *testing.T) {
    expected := &Customer{123,
        []string{},
        []string{},
    }

    got := NewCustomer(123, []string{}, []string{})

    if got.customerID != expected.customerID {
        t.Errorf("Got: %v, expected: %v", got.customerID, expected.customerID)
    }

    if reflect.DeepEqual(got, expected) {
        t.Errorf("Got: %v, expected: %v", got, expected)
    }
}

输出:

Got: &{123 [] []}, expected: &{123 [] []}

reflect.DeepEqual() returns true 正如预期的那样,这就是你的 t.Errorf() 被调用的原因。

如果它们相等,您希望测试失败。您只需否定条件:

if !reflect.DeepEqual(got, expected) {
    t.Errorf("Got: %v, expected: %v", got, expected)
}
