Selenium/Firefox не работает

Question

Я пытаюсь вызвать Firefox с помощью selenium webdriver с помощью Java-кода, открывается браузер Firefox, однако он не запускает никаких тестов и не заканчивается через некоторое время с сообщением об ошибке ниже. Пожалуйста помоги.

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

Answer 1

Это произошло из-за новой проблемы в последнем браузере firefox.

Обновите свои сосуды селена. Новая версия firefox (или другой браузер) не поддерживает старые банки селена.

Скачать как Селен сервер (ранее Selenium RC Server) Селен Клиент & WebDriver Языка Bindings

Замените их старые банки, которые вы используете. Обновление Mozilla также, чтобы вы могли получить обновленные результаты

источник: - http://docs.seleniumhq.org/download/

Чтобы преодолеть от этой проблемы вы должны setPreference, как xpinstall.signatures.required", false в Firefox Profile, а затем передать его в объект драйвера

firefoxProfile.setPreference("xpinstall.signatures.required", false); 

Ниже код работает отлично для меня.

static WebDriver driver=null; 
public static void main(String[] args) { 
final FirefoxProfile firefoxProfile = new FirefoxProfile(); 
firefoxProfile.setPreference("xpinstall.signatures.required", false); 
driver = new FirefoxDriver(firefoxProfile); 
driver.get("https://www.google.de/"); 

Надеется, что это поможет вам :)
