phpunit中具有受保护方法的抽象类

Question

I've been trying to test with phpunit on my abstract class that holds protected methods that will be shared by it children. I've been reading about private/protected methods shouldn't be tested because that makes the code brittle. In this case, I don't want those methods to be public API (although that wouldn't hurt, Its something that doesn't feels right) nor would I want to test in every child if the same parent action is well executed.

So, as an example explains more, I'll try to post a simple one

abstract class AbstractAuthenticator
{
    abstract function authenticate();

    protected function checkUserPrivilege()
    {
        ... code
    }

    protected function checkEnvPrivileges()
    {
        ... code
    }

}

class BasicAuth extends AbstractAuthenticator
{

    public function authenticate()
    {
        $this->checkUserPrivilege();
        $this->checkEnvPrivileges();
        ... code
    }
}

class AjaxAuth extends AbstractAuthenticator
{

    public function authenticate()
    {
        $this->checkUserPrivilege();
        $this->checkEnvPrivileges();
        ... code
    }
}

My questions (if may I do more than one) are:

• Does this code make sense to you?
• Should be protected methods changed to public
• If the protected methods are public, should they be checked outside the class or still be called in authenticate()
• If you see this api (will all methods marked as public) wouldn't you be confused about which methods to invoke?

Thank you all. I think this question is tricky and needs some perspective to look into, so I appretiate your comments

创建一个TestAuth类，并在使用它而不是真实的* Auth对象的AbstractAuthenticatorTest中测试受保护的方法。
