使用Selenium 3.0启动Firefox 46.0.1时获取IllegalStateException [英] Getting IllegalStateException while launching Firefox 46.0.1 using Selenium 3.0

问题描述

我有Selenium版本3.0.1和Firefox版本46.0.1. 在硒3.0.1 更改日志中，提到:

I have Selenium version 3.0.1 and Firefox version 46.0.1. In selenium 3.0.1 changelog it is mentioned that:

Geckodriver现在是自动执行Firefox的默认机制.这 是Mozilla针对该浏览器的驱动程序的实现，并且是 自动化Firefox 48及更高版本所需的

Geckodriver is now the default mechanism for automating Firefox. This is Mozilla's implementation of a driver for that browser, and is required for automating Firefox versions 48 and above

尽管我遇到错误:

java.lang.IllegalStateException:必须通过webdriver.gecko.driver系统属性设置驱动程序可执行文件的路径；有关更多信息，请参见 https://github.com/mozilla/geckodriver .可以从 https://github.com/mozilla/geckodriver/releases 下载最新版本.

java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property; for more information, see https://github.com/mozilla/geckodriver. The latest version can be downloaded from https://github.com/mozilla/geckodriver/releases

在执行以下代码时:

@Test
public void test() {
    WebDriver driver = new FirefoxDriver();
    driver.get("http://www.google.com");
    driver.quit();
}

为什么我仍然收到此错误，但我使用的是Firefox版本< 48.0? 在Selenium 3.0.1中必须同时使用Geckodriver吗?

Why am I getting this error nevertheless I am using Firefox version < 48.0 ? Is it mandatory to use Geckodriver with Selenium 3.0.1 ?

如果进行以下更改，以上代码将正常工作:

Above code is working perfectly if I make following changes:

System.setProperty("webdriver.gecko.driver","path to geckodriver");
WebDriver driver = new FirefoxDriver();

推荐答案

您必须为所有Firefox浏览器设置以下属性，无论从selenium 3.0开始的版本是什么:

you have to set the following property for all Firefox browsers irrespective of the version from selenium 3.0 onwards :

System.setProperty("webdriver.gecko.driver","path to geckodriver");

Geckodriver现在是自动执行Firefox的默认机制.这是Mozilla针对该浏览器的驱动程序的实现，并且是自动化Firefox 48及更高版本所必需的

Geckodriver is now the default mechanism for automating Firefox. This is Mozilla's implementation of a driver for that browser, and is required for automating Firefox versions 48 and above

设置路径为必填项.

如果要在Firefox 47或更低版​​本上运行测试，请将Firefox驱动程序功能木偶"设置为false.

If you want to run the tests on Firefox 47 or before, set the Firefox driver capability "marionette" to false.

DesiredCapabilities d = new DesiredCapabilities();
d.setCapability("marionette", false);  // to disable marionette.
WebDriver driver = new FirefoxDriver(d);
