PhantomJS has a lot of different uses. The interesting bit for me is to use PhantomJS as a lighter-weight replacement for a browser when running web acceptance tests. This enables faster testing, without a display or the overhead of full-browser startup/shutdown.
In future versions of PhantomJS, the GhostDriver component will be included.
So, Ghostdriver is the bridge we need to use Selenium WebDriver with Phantom.JS.
Since it is not available in the current PhantomJS release, you can try it yourself by compiling a special version of PhantomJS:
It was pretty trivial to setup on Ubuntu (12.04):
$ sudo apt-get install build-essential chrpath git-core libssl-dev libfontconfig1-dev $ git clone git://github.com/ariya/phantomjs.git $ cd phantomjs $ git checkout 1.8 $ ./build.sh $ git remote add detro https://github.com/detro/phantomjs.git $ git fetch detro && git checkout -b detro-ghostdriver-dev remotes/detro/ghostdriver-dev $ ./build.sh
Then grab the 'phantomjs' binary it produced (look inside 'phantomjs/bin'). This is a self-contained executable, it can be moved to a different directory or another machine. Make sure it is located somewhere on your PATH, or declare its location when creating your PhantomJS driver like the example below.
For these examples, 'phantomjs' binary is located in the same directory as the test script.
Example: Python Using PhantomJS and Selenium WebDriver.
#!/usr/bin/env python driver = webdriver.PhantomJS('./phantomjs') # do webdriver stuff here driver.quit()
Example: Python Unit Test Using PhantomJS and Selenium WebDriver.
#!/usr/bin/env python import unittest from selenium import webdriver class TestUbuntuHomepage(unittest.TestCase): def setUp(self): self.driver = webdriver.PhantomJS('./phantomjs') def testTitle(self): self.driver.get('http://www.ubuntu.com/') self.assertIn('Ubuntu', self.driver.title) def tearDown(self): self.driver.quit() if __name__ == '__main__': unittest.main(verbosity=2)
