У Thread.local нет атрибута - Owasp Zap, веб-драйвер, салат для автоматического тестирования безопасности

Question

Недавно я участвовал в тестах безопасности, интегрированных с автоматизированными функциональными тестами. Я нашел интересную статью, и я хочу проверить это решение. При запуске с использованием структуры салата, он получает ошибку

"Thread_.local object has no attribute" driver "in file gruyere.py

Gruyere.feature

Feature: Gruyere

  Scenario: Gruyere
    Given I navigate to Gruyere
    When I choose to Agree & Start
    Then I am taken to "Gruyere: Home"

    Given I choose to Sign Up
    When I choose to Create Account with user name 
"blue" and password "cheese"
    Then I am taken to "Gruyere: Error"

    Given I choose to Sign In
    When I choose to Login with user name "blue" and     password "cheese"
    Then I am taken to "Gruyere: Home"
