How do I automate in Selenium?

 Selenium Automation

The most popular and well-developed web automation testing framework is still Selenium. When compared to other popular frameworks like Cypress, Puppeteer, Playwright, and others, it is poised to lead the market in every way. It is one of the best automation frameworks available, with features that are constantly developing. Furthermore, Selenium allows you to use other programming languages, such as C#, Ruby, Perl, Java, Python, and others, as well as multiple operating systems and web browsers, for Selenium automation testing.


Selenium is a package of tools that allows you to create automated web application tests in a variety of programming languages. SeleniumHQ maintains the Selenium project on GitHub, which includes a number of open-source Selenium projects.

The Selenium suite includes the Selenium IDE, Selenium WebDriver, and Selenium Grid, each with its own approach to browser automation.

Automation testing necessitates an in-depth knowledge of numerous automation tools and frameworks.
Due to its ease of use and beneficial capabilities, Selenium is the most popular of these tools. Selenium is a tool for automating and monitoring website testing and performance.

Prerequisites for Selenium Automation

Coding Skilla

A large percentage of testers are unable to code. Even if you're one of the few that does, the time it takes to set up and manage your test cases will quickly outpace the time it takes to manually run the tests.

The rest of the pipeline's integration

You'll need to set up and update the script, as well as ensure sure your code communicates with the rest of the release pipeline. As a result, as a tester, you'll need to know how your Git repository manages code versioning.

Creating suitable test environments

In and of itself, setting up your test environment is a demanding undertaking. Setting up parallel test environments and cross-browser testing with Selenium is possible, but even for a skilled coder, it can take months.

Maintenance

In addition to writing, you'll have to maintain your scripts.
If you're good with programming and have a very experienced programmer with a lot of free time, you might be able to detect and fix any errors in your script.  

Automation steps with Selenium

Before beginning automation testing, there are a few key steps that must be taken to write a test case for the login feature:

1. Make a Selenium WebDriver application

To launch the webpage in the specified browser, set the system properties to the path of that browser's driver. In this demonstration, ChromeDriver will be used to automate logins with Selenium Webdriver.

The following is the syntax for the same:

2. Configure your browser if necessary.

The web page is often in a reduced format when the test case is executed. To see the test cases you've performed more clearly, enlarge your browser's window.
Type the next command to accomplish the same thing:

3. Go to the necessary web page.

Launch the browser and go to the specified URL. For instance, enter the following command to open the URL in your preferred web browser:

4. Find the appropriate web element.

Locators are a crucial part of any Selenium script since they identify the components with which the test script will interact to replicate user activities.

 

 

5. Perform Action on the Located Web Element

Testers must then find the element and carry out the desired activity. In this case, the action is to enter information into the email and password fields before clicking the login button.

The script does this by utilising the click and sendKeys methods, as shown below:

 

6. Verify & Validate the Action

The results can be supported by assertion. When comparing expected and actual results, assertions must be used carefully. If the test case matches, it passes. Otherwise, the test case will not pass.

The final assertion will look like:
