It seems like you code against a specific sub-type and not the parent class Vultr\Tests\TestCase as the method getResponse() does only exist in the following sub-classes of Vultr\Tests\TestCase: Vultr\Tests\Unit\AccountTest, Vultr\Tests\Unit\ApiKeyTest, Vultr\Tests\Unit\ApplicationTest. Maybe you want to instanceof check for one of these explicitly?
                                                                                                                                                                                                                                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Let’s take a look at an example:


abstract class User
{
    /** @return string */
    abstract public function getPassword();
}

class MyUser extends User
{
    public function getPassword()
    {
        // return something
    }

    public function getDisplayName()
    {
        // return some name.
    }
}

class AuthSystem
{
    public function authenticate(User $user)
    {
        $this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
        // do something.
    }
}





In the above example, the authenticate() method works fine as long as you just pass
instances of MyUser. However, if you now also want to pass a different sub-classes
of User which does not have a getDisplayName() method, the code will break.




Available Fixes


  1. Change the type-hint for the parameter:
    

    class AuthSystem
{
    public function authenticate(MyUser $user) { /* ... */ }
}

    

    

    2. 

  2. Add an additional type-check:
    

    class AuthSystem
{
    public function authenticate(User $user)
    {
        if ($user instanceof MyUser) {
            $this->logger->info(/** ... */);
        }

        // or alternatively
        if ( ! $user instanceof MyUser) {
            throw new \LogicException(
                '$user must be an instance of MyUser, '
               .'other instances are not supported.'
            );
        }

    }
}

    

    

    3. 




 Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types
inside the if block in such a case.


  1. Add the method to the parent class:
    

    abstract class User
{
    /** @return string */
    abstract public function getPassword();

    /** @return string */
    abstract public function getDisplayName();
}
