Selenium Python bindings provides a simple API to write functional/acceptance tests using Selenium WebDriver. Through Selenium Python API you can access all functionalities of Selenium WebDriver in an intuitive way.
Selenium Python bindings provide a convenient API to access Selenium WebDrivers like Firefox, Ie, Chrome, Remote etc. The current supported Python versions are 2.7, 3.2 and above.
This documentation explains Selenium 2 WebDriver API. Selenium 1 / Selenium RC API is not covered here.
1.2. Downloading Python bindings for Selenium¶
You can download Python bindings for Selenium from the PyPI page for selenium package. However, a better approach would be to use pip to install the selenium package. Python 3.5 has pip available in the standard library. Using pip, you can install selenium like this:
pip install selenium
1.3. Detailed instructions for Windows users¶
You should have internet connection to perform this installation.
Install Python 3.5 using the MSI available in python.org download page.
Start a command prompt using the
cmd.exeprogram and run the
pipcommand as given below to install selenium.
C:\Python35\Scripts\pip.exe install selenium
Now you can run your test scripts using Python. For example,
if you have created a Selenium based script and saved it inside
C:\my_selenium_script.py, you can run it like this:
1.4. Downloading Selenium server¶
The Selenium server is only required, if you want to use the remote WebDriver. See the Using Selenium with remote WebDriver section for more details. If you are a beginner learning Selenium, you can skip this section and proceed with next chapter.
Selenium server is a Java program. Java Runtime Environment (JRE) 1.6 or newer version is recommended to run Selenium server.
You can download Selenium server 2.x from the download page of
selenium website. The file name
should be something like this:
selenium-server-standalone-2.x.x.jar. You can always download the
latest 2.x version of Selenium server.
If Java Runtime Environment (JRE) is not installed in your system, you can download the JRE from the Oracle website. If you are using a GNU/Linux system and have root access in your system, you can also use your operating system instructions to install JRE.
If java command is available in the PATH (environment variable), you can start the Selenium server using this command:
java -jar selenium-server-standalone-2.x.x.jar
Replace 2.x.x with actual version of Selenium server you downloaded from the site.
If JRE is installed as a non-root user and/or if it is not available in the PATH (environment variable), you can type the relative or absolute path to the java command. Similarly, you can provide relative or absolute path to Selenium server jar file. Then, the command will look something like this:
/path/to/java -jar /path/to/selenium-server-standalone-2.x.x.jar
