Generate Valid Random Faker Values in Go-CodePudding

I am using Validator package. I have the next Struct:

type User struct {
    Name       string `validate:"required"`
    Email      string `validate:"required,email"`
    CreditCard string `validate:"credit_card"`
    Password   string `validate:"min=8,max=255"`
}

What can I do to generate valid random values for thats fields?

CodePudding user response：

You can use faker package. It has functions like FirstName(), Email(), CCNumber(). You can also use tags (one, two) with this package in your struct.

CodePudding user response：

If you're writing tests, you can use Fuzzing (implemented in Go 1.18).

Would look like this:

import "testing"

func TestHello(f *testing.F) {
    // Add your seeds here
    f.add("John", "[email protected]", "1234-5678-1234-5678", "@HelloWorld123")
    
    f.Fuzz(func(t *testing.T, name, email, creditCard, pass string)  {
        // Write your test here
    }))
}

Then run:

$ go test -fuzz
