    basic selenium interview questions: 7 Selenium Interview Questions and Example Answers

    Introduction

    Selenium Interview Questions and Answers for experienced Selenium QA Testers, Software Testers & Automation Engineers.

    What is Selenium framework?

    Selenium is a framework for testing web applications. It allows you to write tests in the same language as your application under test, which makes it easier to read and maintain your tests.

    Selenium tests are written using Selenium Commands, which are then executed by an engine (Selenium Server). Tests can be written using any programming language that can communicate with this server, such as Java or Ruby.

    How to write a test script using the Selenium IDE?

    • Create a new project.
    • Create a test case and add it to the project.
    • Write your test script code in the editor window and save it when done, or use import statements to pull in external files that contain your test scripts if you prefer not to write them directly into Selenium IDE’s editor window.

    What are the different types of locators in selenium?

    There are several types of locators in selenium.

    • By ID: The id attribute is unique and it’s different for every element on the page. This makes it easy to identify an element because its value will never change.
    • By ClassName: You can use this attribute or its value to identify elements that belong to a particular class or CSS style (e.g., “div”).
    • LinkText: This locator type allows you to search for links by their text content only (e.g., “Click here!”). If you want your test script to click on any link with this text content then use this type of locator along with Selenium WebDriver’s click() method call; however, if there are multiple links on the same page with similar content then only one will be clicked!

    What is the difference between assert command and verify command in selenium?

    The assert command is used to assert that a certain condition is true. The verify command is used to assert that a certain condition is false. For example, if you have an email field and want to check whether it has been filled or not, then you can use the assert command as follows:

    assert webElement(By.id(“email”).isPresent())

    How to add conditional code in selenium automated test script using If Statement?

    • You can use if statement to execute a particular set of statements if the condition is true.
    • If statement should be used in the beginning of the test script.
    • If statement should be used after webdriver has been instantiated and it will take care of all other objects like browser, elements, locators etc.

    What is the use of executeScript() method in Selenium Webdriver program?

    The executeScript() method is used to execute a script in the browser. It’s an advanced method, which you can use to run JavaScript code on your webpages. To do this, it requires you to pass two parameters:

    • The path of your script file (which should be in the same folder as where you have written your Selenium Webdriver program).
    • A String value that tells Selenium what function should be called on initialization of that file (for example: window.onload = function() {…}).

    How will you avoid conflict while running multiple tests simultaneously on multiple browsers?

    You should be able to avoid conflicts by using the same browser, version and operating system. You can also use the same virtual machine if you want to test a website that is hosted on multiple servers.

    If you’re running tests in parallel on multiple browsers, make sure that you don’t have two instances of Chrome running at the same time.

    • What is Selenium?

    Selenium is a framework used for automating web applications. It provides support for browsers like Chrome, Firefox and Internet Explorer. Selenium supports many programming languages such as Java, C# etc., which are used by the developers to write tests in their own language instead of JavaScript or Ruby that comes with Selenium WebDriver (SWD). The main advantage of using SWD over other alternatives is that it can be executed on any machine without any dependencies on specific browsers or operating systems.
