Selenium Interview Question and Answers
Selenium Interview Question and Answers
Q: What is Selenium?
A: Selenium is an open-source automation testing tool that is widely used for web application testing. It allows testers to automate functional and regression tests for web applications across various browsers and platforms.
Q: What are the different components of Selenium?
A: The different components of Selenium are:
• Selenium IDE
• Selenium WebDriver
• Selenium Grid
• Selenium RC (deprecated)
Q: What is Selenium WebDriver?
A: Selenium WebDriver is a web automation framework that allows you to write test scripts to automate web browser actions. It interacts directly with the browser using the browser’s native support for automation.
Q: What programming languages can you use with Selenium WebDriver?
A: Selenium WebDriver supports multiple programming languages, including Java, C#, Python, Ruby, and JavaScript.
Q: How do you identify elements in Selenium WebDriver?
A: Elements can be identified in Selenium WebDriver using locators. There are several types of locators, including ID, name, class name, tag name, link text, and partial link text.
Q: What is the difference between findElement() and findElements() in Selenium WebDriver?
A: The findElement() method returns the first matching element on the page, while the findElements() method returns a list of all matching elements on the page.
Q: What are the different types of waits in Selenium WebDriver?
A: The different types of waits in Selenium WebDriver are:
• Implicit wait
• Explicit wait
• Fluent wait
Q: What is an implicit wait in Selenium WebDriver?
A: An implicit wait is a setting that instructs the WebDriver to wait for a certain amount of time before throwing a “NoSuchElementException”. It is applied globally to all elements.
Q: What is an explicit wait in Selenium WebDriver?
A: An explicit wait is a type of wait in Selenium WebDriver that waits for a certain condition to occur before moving on to the next step in the test script.
Q: What is a fluent wait in Selenium WebDriver?
A: A fluent wait is a type of explicit wait in Selenium WebDriver that allows you to wait for a certain condition to occur with a maximum time limit. It also allows you to set the polling interval, which is the amount of time between each check for the condition.
Q: What is Selenium Grid?
A: Selenium Grid is a tool that allows you to run tests in parallel across multiple browsers and platforms. It allows you to run tests on multiple machines, which can greatly reduce the time it takes to run a large test suite.
Q: What is a Page Object Model in Selenium?
A: The Page Object Model is a design pattern for organizing Selenium code in a way that separates the page structure and elements from the test code. It involves creating a separate class for each page or component of the application being tested, which contains the elements and actions for that page.
Q: What is a framework in Selenium?
A: A framework in Selenium is a set of guidelines, best practices, and tools that are used to structure and organize Selenium code for efficient and effective test automation. There are different types of frameworks, including data-driven, keyword-driven, and hybrid frameworks.
