Use Python with Selenium: You can use Python with selenium for testing. Selenium is a tool for testing web applications. Python, as we know is a high-level object-oriented programming language. As Python uses simple English keywords it is very compatible for the user. Python is easy to interpret because it is designed in a user-friendly manner. Python has fewer syntax complications when compared with other programming languages.
Selenium is a testing tool which can test your web applications. You can use it in various ways i.e, for instance, you can use it to
1) Permit to tap buttons
2) Enter content in structures
3) Skim your site to check whether everything is ‘OK’ or not and so on.
As the Python API’s empower you to connect with Selenium, Selenium sends the standard Python commands to various browsers despite the variation in their browser’s design. Similarly, you can run Python scripts for various browsers like Chrome, Firefox, IE, etc. on different operating systems.
Python with Selenium
As Python is a pretty user-driven environment, you can use Python with Selenium in a simple way. You just need to install some drivers and selenium web tool to use Python with selenium. Here is the process on how you can use Python language with Selenium.
Python’s API allows Selenium to access the Python language. Selenium Python bindings provide a simple API to write functional/acceptance tests using Selenium Web Driver. Through Selenium Python API you can access all functionalities of Selenium Web Driver in an intuitive way. Selenium Python bindings provide a convenient API to access Selenium Web Drivers like Firefox, IE, Chrome, Remote etc.
Downloading Python bindings for Selenium
One can download the Python bindings from the PYPI installation page. However, a better way would be to pip to install the Selenium package. Using the pip, you can install Selenium in this way.
pip install selenium
Selenium requires a driver to interface with your browser. Every browser has a set of drivers to be installed before you can get access to them through Selenium. You also need to make sure that it’s in your path. Ignoring this step would give you an error. All the other supported browsers will have their own driver links. Here are some of the examples for driver links.
Google Chrome: https://sites.google.com/a/chromium.org/chromedriver/downloads
Mozilla Firefox: https://github.com/mozilla/geckodriver/releases
Downloading Selenium Servers
In general, the Selenium server is a Java program. A version of Java Run time Environment (1.6) or newer is recommended to access the Selenium servers. 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
If JRE(Java Runtime Environment) 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 a relative or absolute path to the
/path/to/java -jar /path/to/selenium - server - standalone - 2.x.x.jar
Using Python for i in range is a extensive topic. To know more about how to use Python for i in range, you can explore the link highlighted below.
Now, if you have installed the selenium python bindings then you can start using it from the Python as below.
The above script can be saved onto a file and later can be run like this,
Make sure that the Python you are running has the selenium module installed.
You can also use Python in String functions. To know how you can deal with strings in Python, explore the link below.
Why to use Python over Java in Selenium?
Here are a few reasons why Python is preferred over Java in Selenium. Refer them below,
a) The programs in Java tend to run slower in selenium when compared to the programs in Python.
b) While Python uses Indentation, Java uses traditional braces to start and end blocks.
c) Java employs static typing, while Python is dynamically typed.
d) Python is simpler and more compact compared to Java.
Using Selenium to write Tests
Selenium is mostly used for writing test cases. The selenium package itself doesn’t provide a testing tool/framework. You can write test cases using Python’s unit test module. The other options for a tool/framework are py.test and nose. This is a test for python.org search functionality:
You can run the above program from a shell like this,
Ran 1 test in 15.566s
Using Selenium with Web drivers
To use the remote Web Driver, you should have Selenium server running. To run the server, use this command:
java -jar selenium-server-standalone-2.x.x.jar
Here is a basic example,
Here are a few
How do I automate in Python?
The Seven Basic Steps of Selenium Tests
a) Create a WebDriver instance.
b) Navigate to a Web page.
c) Locate an HTML element on the Web page.
d) Perform an action on an HTML element.
e) Anticipate the browser response to the action.
f) Run tests and record test results using a test framework.
g) Conclude the test.
a) Download and Add required Jar Files In Project’s Build Path.
b) Disable the default listeners of Test.
c) Add Report NG listeners to testng.xml file.
d) Execute your test and look the Report NG reports.
