This post documents how to set up an Ubuntu 14.04 64-bit machine with everything you need to develop automated tests with Selenium-WebDriver, Google Chrome, and ChromeDriver, using the Python 2.7 release that ships with Ubuntu.
These steps might be useful to someone in the near term, and perhaps in the future this post could make for an interesting time capsule - remembering the WebDriver that was!
All steps assume you've just booted a fresh Ubuntu 14.04 64-bit machine and are at the command prompt:
1. Download and install the latest Google Chrome release
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb sudo dpkg -i --force-depends google-chrome-stable_current_amd64.deb
2. Download and install the latest amd64 chromedriver release
Here we use wget to fetch the version number of the latest release, then plug the version into another wget invocation in order to fetch the chromedriver build itself:
LATEST=$(wget -q -O - http://chromedriver.storage.googleapis.com/LATEST_RELEASE) wget http://chromedriver.storage.googleapis.com/$LATEST/chromedriver_linux64.zip
Symlink chromedriver into /usr/local/bin/ so it's in your PATH and available system-wide:
unzip chromedriver_linux64.zip && sudo ln -s $PWD/chromedriver /usr/local/bin/chromedriver
3. Install pip and virtualenv
Using virtualenv allows you to install the Selenium Python bindings (and any other Python modules you might want) into an isolated environment, rather than the global packages dir, which (among other benefits) can help make your test environment easily reproducible on other machines:
$ python -V Python 2.7.6 $ sudo apt-get install python-pip $ sudo pip install virtualenv
4. Create a dir in which to install your virtualenv environment, and install and activate a new env
More documentation on what's being done here is available in the virtualenv docs.
mkdir mytests && cd $_ virtualenv env source env/bin/activate
5. Install the Selenium bindings for Python in your virtualenv
$ pip install selenium Collecting selenium Downloading selenium-2.44.0.tar.gz (2.6MB) 100% |################################| 2.6MB 1.8MB/s Installing collected packages: selenium Running setup.py install for selenium Successfully installed selenium-2.44.0
6. Launch Python in interactive mode, and briefly ensure you can launch a browser with ChromeDriver
Once the browser is open, navigate to www.google.com and print the document title:
$ python Python 2.7.6 (default, Mar 22 2014, 22:59:56) [GCC 4.8.2] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from selenium import webdriver >>> d = webdriver.Chrome() >>> d.get("http://www.google.com/") >>> d.title u'Google'
That's all you need to get started - the next step I would suggest is to explore how to run Selenium scripts using pytest or unittest. That sounds like good territory to cover in a subsequent post, so perhaps I'll revisit it!
