Now that you have recapitulated the introduction to Selenium, it’s time to address another common question.
Take a look below!
The Advantages of Using Selenium
Selenium is the most widely-used platform in the world. Ever wondered what makes it so unique? Yes, you’ve guessed it correctly!
Selenium offers numerous benefits to organizations. Hence, it is a popular framework in the industry.
Here are the top advantages of using Selenium in the company.
- Language Compatibility
Selenium works well with numerous programming languages. You can code in any language of your choice, and Selenium will automatically modify it to a platform-compatible model.
So, you can use any language to write your codes on Selenium. That’s the primary reason behind every company using Selenium and not hiring any additional employees.
Selenium is a free platform. The companies need not buy original copies of the software before running automated testing. So, it comes in handy for such businesses as they do not require allocating budgets to purchase the Selenium framework.
Selenium supports all popular web browsers. It works primarily with all browsers from Chrome to Microsoft and Safari. So, businesses need not use separate platforms for each browser and access convenience, speed, and cost savings.
4.Multiple Operating System Compatibility
Like web browsers, Selenium remains compatible with multiple operating systems. It works seamlessly with Windows, Linux, Mac, and whatnot. So, companies adapting Selenium can use one platform for all OS at a given time.
Top 15 Selenium Interview Questions and Answers
Here are the best Selenium interview questions and answers.
- Explain the differences between Selenium 2.0 and Selenium 3.0.
Selenium 2.0 is a program that simplifies the creation of automated web application tests. Although Selenium RC has been deprecated after the merge, it is still backward compatible.
Selenium 3.0 is a version of Selenium 2.0 that has been enhanced. It is backward compatible by default and does not use Selenium RC. The latest version included various bug fixes as well as improved stability.
2.What exactly do you mean by the same-origin policy?
The Same Origin policy is a robust security feature that Selenium uses. According to this principle, a web browser permits scripts from one web page to access the contents of another web page if both pages have the exact origin.
3.What do you mean by Selenese?
The Selenium commands used to test your web application are known as Selenese.
4.What are Web Locators? Name its types.
The Locator command instructs Selenium IDE on which GUI items it should test.
5.Name the types of waits supported by WebDriver.
- Implicit wait
- Explicit wait
- Fluent wait
- 6.Name different types of navigation commands.
- 7.Differentiate between driver.close() and driver.quit().
The function driver.close() closes the current browser window. When the driver instance uses the quit() method while one or more browser windows are open, all open browsers are closed.
8.What Exactly is Page Object Model?
The Page Object Model is a design paradigm that aids in creating web element object repositories.
9.Can you automate Captcha?
Captcha cannot be automated with Selenium. The automation test engineer must type the Captcha manually, whereas other areas can be filled automatically.
10.How does Selenium deal with pop-ups in Windows?
Selenium does not support Windows-based functionality natively. The third-party technologies such as AutoIT, Robot, and others combine with Selenium to handle pop-ups and other Windows-based features.
11.What do you mean by pause on an exception in Selenium IDE?
By pressing the pause symbol in the top right corner of the IDE, the user can use this feature to manage exceptions.
12.What do you mean by exception test in Selenium?
An exception test is a scenario in which you expect an exception to be thrown within a test class. You can use the @Test annotation if a test case is written to throw an exception.
13.What do you mean by assertion?
Assertion confirms that the application’s current state is as expected.
14.What are the different types of assertion?
The types of assertion are “assert,” “verify,” and “waitFor.”
15.Differentiate between verify and assert commands.
Assert allows you to determine whether or not an element is present on the page. If the asserted feature is not available, the test will fail at that step. The verify command will check if the element is present on the page; if not, the test will run.
Hopefully, you find it hopeful. Good luck with your learning!
