Selenium is an open-source technology mostly used for web browser testing and automation. It offers a unified user interface and allows users to develop test scripts in various programming languages. Selenium supports various programming languages, including PHP, Perl, Python, and others. Selenium is well-known in the testing community because it includes a replay tool that allows functional testing across several web browsers. Users can utilise Selenium for testing without having to learn a testing script language, thanks to this functionality.

Selenium is preferred by freelance developers and U.I. engineers for testing their code or apps. This is because Selenium is more flexible and has a broader scope for web automation.

  1. What are the limitations of Selenium testing?

As Selenium is open-source, there is no reliable technical support for it. Users have to rely on the support of the online community to resolve their queries. Selenium supports web applications only and is not suitable for customised hardware. There is limited support for Image testing, which makes it difficult for users to finish their tasks. Some users also feel that setting up a test environment in Selenium is difficult when compared to RFT, SkillTest, etc.

  1. What 4 conditions must be met for Selenium to pass a test?

The 4 conditions that must be met for Selenium to pass a test are:

  • URL - The application URL triggers the test case.

  • Host - Selenium can be bound to a specific IP address instead of a host on a local server.

  • Browser - This is where the Selenium script needs to be executed.

  • Port Number - Users can specify the port number to connect the Selenium tests to the Grid. Users need to ensure that there are no applications with the same port number in any location on the same machine.

  1. Is coding required for Selenium?

Yes, having at least a basic knowledge of Java is recommended for learning Selenium. This will allow you to create simple test automation scripts with Selenium WebDriver API. But if you don't have any knowledge of Java, then you can create your tests using the Record and Play feature of the Selenium IDE. This is a GUI based tool in Selenium that only works in Mozilla Firefox.

  1. What can’t we automate using Selenium?

We cannot automate testing on customised or embedded hardware using Selenium. This is because Selenium is designed for web applications only. Manual testing is the better option in such scenarios, as automated testing takes too much time. This defeats the main purpose of automated testing, which is to accomplish tasks faster to save time and effort.

  1. Why is Maven used in Selenium?

Maven is an automation tool used to build and manage projects in different programming languages. It is used in Selenium because it provides information present in pom. This information includes

  • Unit test reports

  • Mailing lists

  • Dependency lists

  • Cross referenced sources, etc.

Maven also manages the users build compilation, documentation, and other project related tasks.

  1. What is SDLC?

SDLC refers to the Software Development Life Cycle in which testing is the most important phase. There are 2 types of testing

  • Manual Testing: Test case scenarios are checked manually to detect errors and bugs. This process is suitable for unique hardware and is time consuming.

  • Automated Testing: Use of an automated system to validate test case scenarios. This process eliminates the need for manual testing and helps in saving time and effort.

  1. What is the latest Selenium version?

The latest version of Selenium is Selenium4, which was launched on October 13, 2021. Important changes in Selenium 4 include:

  • Support has been removed for Opera and PhantomJS. Opera users need to switch to Chrome, while PhantomJS users can switch to Chrome or Firefox.

  • Grid now supports advanced tools like Docker, AWS, and Azure. Now the Grid also has a more user-friendly UI and carries information about the current session, capacity, etc.

  1. Which locator is faster in Selenium?

The ID locator is the fastest locator in Selenium. This is preferred by most users to locate their preferred WebElements on a page. The ID locators are unique for each element on the page; this makes them faster than other locators.

  1. What is TestNG in Selenium?

This is a Java testing framework on the lines of JUnit and NUnit. TestNG has new properties and does not have the constraints of JUnit. These improved features make TestNG a better choice.

  1. Can we compare two images in Selenium?

To compare two images in Selenium, you need to take a screenshot of the original image and save it. A screenshot of the same image needs to be captured while automating the web application. Both the images can then be compared with each other.

  1. What happens if ‘Verify’ fails in Selenium?

In such cases, the test will continue and the failure will be logged. If there is a ‘WaitFor’ command, then the test stops if the condition is false. The condition in this command needs to be met within the specified timeout setting.

  1. Which is faster: CSS or XPath?

CSS is faster than XPath on most browsers. This is because the CSS selectors perform faster and are more reliable than XPath. These selectors are also easier to read and understand as they are shorter than XPath.

  1. What is Jenkins in Selenium?

Jenkins is an open-source CI (Continuous Integration) server. The build and deploy process of web applications gets automated through Jenkins. By using Jenkins for Selenium testing, users can automate testing as a part of the build process.

  1. What is the difference between close and quit on Selenium?

When we use close() only the current window in which Selenium is running the test is closed. Other windows in the WebDriver session remain active and do not get affected. But, the quit() closes all browser windows and ends the entire session.
