Requirements to Execute Python Selenium Scripts
Installing the Selenium package using pip provides a simple starting point for running Selenium tests with Python. In addition, in order to use your preferred online browser, you need to download some drivers. The links to get drivers for browsers like Chrome, Edge, Firefox, and Safari are easily found on the internet. We will be using selenium Chromedriver in this instruction. Once you have the correct driver installed for your browser, continue with Selenium setup and browser installation.
Important to note is that downloading the package and drivers is sufficient if you plan to run Selenium tests only locally. On the other hand, the Selenium Server installation is required if you intend to use Selenium on a remote server. Java is used to write Selenium Server.
How to Run Your First Test with Python and Selenium
In order to launch your first Selenium test with Python, first import the WebDriver and Keys classes from Selenium. The Keys class makes it easier to simulate keyboard keystrokes, and the WebDriver class connects to a browser instance.
Once the Selenium package has been installed and the necessary modules have been imported, launch a new Chrome instance with the driver path that you downloaded from Chrome’s official website or your favorite browser. To load a webpage, use the driver’s.get() method, which by default waits for rendering to be finished before continuing.
After the page loads successfully, use the.title attribute to access the webpage’s title. In the search field, type a query by selecting the relevant HTML DOM element, entering a value,
After the page loads successfully, use the.title attribute to access the webpage’s title. In order to submit a search query in the search bar, choose the relevant HTML DOM element, enter a value, and then simulate pressing the Return key to submit the form.
After these steps, use the.close() method to break the connection with the browser in order to end the current session.
In order to interact with HTML DOM elements, you can further navigate them using different selection options.
Exploring Advanced Techniques and Features with Selenium Python Bindings
Selenium Python bindings present an array of advanced techniques and features that can enhance your test automation initiatives.
