Golang : reflect. DeepEqual 返回意外的 false

Question

我有以下代码和代码测试，由于某种原因，deepEqual 返回 false 并且测试失败。现在，通过阅读有关此内容的 doco，我希望对于如此简单的事情来说，这是正确的？任何积分将不胜感激。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 [] []}

Answer 1

reflect.DeepEqual() 按预期返回 true，这就是调用 t.Errorf() 的原因。

如果它们不相等，您希望测试失败。您只需否定条件即可:

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