In System.setProperty(“webdriver.gecko.driver”, “”), what is meant by “Path to your WebDriver”?

问题

I have this exception since I upgraded to 3.0 beta with Firefox.

Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.gecko.driver system property

回答1:

It seems now we need to manually download and set path to the driver executable for Mozilla Firefox also just like chromedriver.

Following is what you need to do:-

Go to http://docs.seleniumhq.org/download/
Scroll down to "Third Party Drivers, Bindings, and Plugins" section on downloads page
Click on Mozilla GeckoDriver and download(zip) latest version v0.10.0 for your operating system.
Extract on your desired location i.e. c:\GeckoDriver\geckodriver.exe

Now you need to set system property and write following lines to initialize FireFoxDriver object:-

System.setProperty("webdriver.gecko.driver", "C:\GeckoDriver\geckodriver.exe");

WebDriver driver = new FirefoxDriver();

driver.get("http://seleniumhq.com");

Thats it!

回答2:

System.setProperty("webdriver.gecko.driver","C://Program Files (x86)//geckodriver-v0.11.1-win64//geckodriver.exe");
String testurl = "http://www.seleniumhq.com";
WebDriver driver = new FirefoxDriver();
driver.get(testurl);

Normally this happens when the FF version is above 45 and thats when we download gecko driver (https://github.com/mozilla/geckodriver/releases). After this unzip the contents of the folder and drag and drop the exe file of gecko driver to this folder (src/main/resources) if you have created a maven project.

We use System.setProperty to provide the path of chromedriver/iedriver etc. Below is the declaration of java.lang.System.setProperty() method:

public static String setProperty(String key, String value)

key : Name of the system property

value: Value of the system property

e.g. System.setProperty("webdriver.chrome.driver", "src/test/resources/chromedriver.exe");

webdriver.chrome.driver : Chrome Driver (Name of system property) src/test/resources/chromedriver.exe : Path of chromedriver (value of system property)

Usually, we encounter IllegalArgumentException when key is empty.
