我正在尝试启动 Mozilla,但仍然收到此错误:
Exception in thread "main" 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
我正在使用 Selenium 3.0.01
Beta 版和 Mozilla 45
。我也尝试过使用 Mozilla 47
。但还是一样。
最佳答案
Selenium
客户端绑定(bind)将尝试从系统 PATH
定位 geckodriver
可执行文件。您需要将包含可执行文件的目录添加到系统路径。
在 Unix 系统上,如果您使用 bash 兼容的 shell,您可以执行以下操作将其附加到系统的搜索路径:
export PATH=$PATH:/path/to/geckodriver
在 Windows 上,您需要更新 Path 系统变量以将完整目录路径添加到可执行文件。原理和Unix上的一样。
以下所有使用任何编程语言绑定(bind)启动最新版 firefox 的配置都适用于 Selenium2
以显式启用 Marionette。使用 Selenium 3.0 及更高版本,您无需执行任何操作即可使用 Marionette,因为它已默认启用。
要在测试中使用 Marionette,您需要更新所需的功能以使用它。
Java:
因为异常明确表示您需要从 here 下载最新的 geckodriver.exe
并将下载的 geckodriver.exe
路径设置为您计算机中存在的系统属性,并在启动 marionette 驱动程序和启动 firefox 之前使用变量 webdriver.gecko.driver
如下:-
//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");
//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities);
对于 Selenium3
使用:-
WebDriver driver = new FirefoxDriver();
If you're still in trouble follow this link as well which would help you to solving your problem
.NET:
var driver = new FirefoxDriver(new FirefoxOptions());
Python:
from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True
# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"
driver = webdriver.Firefox(capabilities=caps)
ruby :
# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox
Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true
JavaScript (Node.js):
const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;
var capabilities = Capabilities.firefox();
// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);
var driver = new webdriver.Builder().withCapabilities(capabilities).build();
使用 RemoteWebDriver
如果您想在任何语言中使用 RemoteWebDriver
,这将允许您在 Selenium
Grid 中使用 Marionette
。
Python:
caps = DesiredCapabilities.FIREFOX
# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True
driver = webdriver.Firefox(capabilities=caps)
ruby :
# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox
caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps
Java:
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);
WebDriver driver = new RemoteWebDriver(capabilities);
.NET
DesiredCapabilities capabilities = DesiredCapabilities.Firefox();
// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);
var driver = new RemoteWebDriver(capabilities);
注意:就像其他浏览器供应商提供给 Selenium 的其他驱动程序一样,Mozilla 现在发布了一个可以与浏览器一起运行的可执行文件。关注 this了解更多详情。
