Unable to launch Firefox in selenium 3.0-beta3 with geckodriver 0.10 using Javascript with selenium's own sample

just want to learn Selenium testing beginning with it's own sample. However, after everything is set up(Node.js, Selenium), when I want to use selenium-webdriver's own sample, it is not working:

This is the official code(name is google_search.js) provided by selenium:

var webdriver = require('selenium-webdriver'),
    By = webdriver.By,
    until = webdriver.until;

var driver = new webdriver.Builder()
    .forBrowser('firefox')
    .build();

driver.get('http://www.google.com/ncr');
driver.findElement(By.name('q')).sendKeys('webdriver');
driver.findElement(By.name('btnG')).click();
driver.wait(until.titleIs('webdriver - Google Search'), 1000);
driver.quit();

This code is within example folder, in Node.js cmd, I cd to node_modules\selenium-webdriver\example, and put geckodriver in this folder, then run node google_search.js Here's the result:

C:\Users\username\node_modules\selenium-webdriver\lib\promise.js:2291
        throw error;
        ^

WebDriverError: Unable to parse new session response: {"error":"unknown error","

 location, no 'firefox_binary' capability provided, and no binary flag set on th

Did I do anything wrong? Can anyone tell me why the offical sample is not launching firefox? Thanks!

Solution

  • I had the same error-message when trying to run a C#-application with Selenium 3.0.0.

    The problem was that I was using the x64 Geckodriver.exe. After downloading and copying the 32bit version to my bin-folder, everything worked well.
