Selenium 2.53.1 does not work on FireFox 48

问题

I am using selenium to test our websites. When I build the project, there is an Exception :-

OpenQA.Selenium.WebDriverException: Failed to start up socket within 45000 milliseconds. Attempted to connect to the following addresses: 127.0.0.1:7055 and the problem is from the code

IWebDriver driver = new FirefoxDriver();

Anybody knows how to solve this problem?

回答1:

Just like the other drivers available to Selenium from other browser vendors, Mozilla has released an executable that will run alongside the browser.

You can download the latest executable geckodriver from here

Add downloaded executable geckodriver to system path

The Selenium client bindings will try to locate the geckodriver (or wires) executable from the system path. You will need to add the directory containing the executable to the system path.

• On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:

  export PATH=$PATH:/path/to/directory/of/executable/downloaded/in/previous/step
  

• On Windows you need to update the Path system variable to add the full directory path to the executable geckodriver. The principle is the same as on Unix.

After all above stuff you need to Initialize FireFoxDriver as below :-

var driver = new FirefoxDriver(new FirefoxOptions());

Note :- Follow this link for the solution of this problem with other programming language.

This answer didn't worked with me. Running selenium 2.53.6 and firefox 47 n 48.

I would recommend downloading firefox 46 which seems to be the best match for selenium 2.53.x.

https://ftp.mozilla.org/pub/firefox/releases/46.0.1/win64/en-US/

Once I downgraded to firefox 46.0.1 everything was working as expected.
