10+ Sdet Automation Test Engineer Interview Questions and Answers for Freshers

To wait in Selenium, we can use explicit and implicit waits. To find all links in a page using XPath, we can use the findElements() method.

• To wait in Selenium, we can use explicit wait with ExpectedConditions or implicit wait with the setScriptTimeout() method.

• Explicit wait waits for a certain condition to occur before proceeding with the next steps.

• Implicit wait sets a maximum time for the driver to wait for an element to appear.

• To find all links in a page using XPath, we ca...read more

Page Object Model (POM) is a design pattern used in test automation to create an object repository for web UI elements.

• POM helps in creating reusable and maintainable code by separating the test logic from the page-specific details.

• Each web page is represented as a separate class, and the UI elements and their actions are defined as methods within that class.

• POM improves code readability, reduces code duplication, and enhances test maintenance.

• TestNG annotations are used in T...read more

To handle alerts in Selenium, we use the Alert interface and its methods.

• To switch to an alert, we use the switchTo() method of WebDriver class.

• To accept or dismiss an alert, we use the accept() or dismiss() method of Alert interface.

• To get the text of an alert, we use the getText() method of Alert interface.

• To send text to an alert, we use the sendKeys() method of Alert interface.

To take a screenshot in automation testing, use the built-in methods provided by the testing framework.

• In Selenium, use the getScreenshotAs() method to capture a screenshot.

• In Appium, use the getScreenshotAs() method to capture a screenshot.

• In TestNG, use the ITestResult interface to capture a screenshot on test failure.

• In Cucumber, use the After hook to capture a screenshot after each scenario.

There are 8 locators present in Selenium.

• Selenium provides 8 different locators to identify elements on a web page.

• The locators are: ID, Name, Class Name, Tag Name, Link Text, Partial Link Text, CSS Selector, and XPath.

• Each locator has its own syntax and usage.

• For example, to locate an element by ID, you can use driver.findElement(By.id("elementId"));

Dynamic elements in Selenium are handled using techniques like explicit waits, fluent waits, and dynamic locators.

• Use explicit waits to wait for a specific condition to be met before interacting with the element

• Use fluent waits to wait for an element to be present and visible before interacting with it

• Use dynamic locators like XPath with functions to locate elements that change dynamically

PUT is used to update or replace an existing resource, while POST is used to create a new resource.

• PUT is idempotent, meaning multiple identical requests will have the same effect as a single request

• POST is not idempotent, meaning multiple identical requests may have different effects

• PUT requires the client to specify the URI of the resource to update, while POST does not

• PUT is typically used for updating existing resources, while POST is used for creating new resources

Smoke testing is a quick test to check if the build is stable, while sanity testing is a more thorough test to check if the specific functionalities are working as expected.

• Smoke testing is done to ensure the stability of the build before further testing, while sanity testing is done to ensure the specific functionalities are working correctly.

• Smoke testing is a subset of regression testing, while sanity testing is a subset of acceptance testing.

• Smoke testing is usually done ...read more

POM (Page Object Model) is a design pattern used in test automation to create reusable and maintainable code by separating page objects from test scripts.

• Create a separate class for each web page or component

• Encapsulate the web elements and their actions within the page class

• Use methods in the page class to interact with the web elements

• In test scripts, instantiate the page class and call its methods to perform actions on the page

Program to find duplicates in an array.

• Iterate through the array and compare each element with the rest of the elements.

• If a match is found, add it to a separate array or print it.

• Use a hash table to keep track of the frequency of each element.

• Sort the array and compare adjacent elements to find duplicates.
