A UserService method that calls the UserRepository a few times

Question

I'm trying to implement some domain driven design architecture, such as a repository to talk to the database, and a service that talks to the repository.

I have an action where I want to see if a User exists, and if he does, update his data, if he doesn't, create it and then perform a task (this could be done using event listeners but I'm not there yet).

• Now I'm wondering if my service method can do all these things? Is there another actor that should be responsible for this?
• This method is not very testable, since it's performing multiple actions? How would I test a method like this?

public function updateOrCreate($data)
{
    $userData = static::getUserDataFromAccessToken($data);

    // Find the user
    $user = $this->userRepository->find($userData['id']);

    // If we found the user, update and return
    if ($user) {
        $this->userRepository->update($userData);

        // Return the updated user
        return $this->userRepository->find($userData['id']);
    }

    // Else create
    $created = $this->userRepository->create($userData);

    if ($created) {

        // Get the newly created user
        $user = $this->userRepository->find($userData['id']);

        // Get the activities
        $this->activityTask->perform($user);

        return $user;
    }
}

public static function getUserDataFromAccessToken($token): array
{
    return [
        'id' => $token->getValues()['athlete']['id'],
        'username' => $token->getValues()['athlete']['username'],
        'photo' => $token->getValues()['athlete']['profile'],
        'access_token' => $token->getToken(),
        'refresh_token' => $token->getRefreshToken(),
    ];
}
