Fluent wait is a dynamic wait mechanism in Selenium WebDriver that waits for a condition to be true before proceeding.

• Fluent wait is used to handle dynamic web elements that may load at different times.

• It can define the maximum amount of time to wait for a condition, as well as the frequency of checking.

• Example: WebDriverWait wait = new WebDriverWait(driver, 10); wait.until(ExpectedConditions.visibilityOfElementLocated

I am an Automation Engineer with experience in designing and implementing automated test scripts for web applications.

• Designed and implemented automated test scripts using Selenium WebDriver for regression testing

• Collaborated with developers to integrate automated tests into continuous integration pipeline

• Performed manual testing to identify bugs and validate automated test results

Automate a test case for Makemytrip website

• Use Selenium WebDriver to automate the test case

• Identify the test scenario, such as searching for a flight

• Write test scripts in a programming language like Java or Python

• Use test data to validate the functionality of the website

• Implement assertions to verify expected outcomes

Locator in Selenium is used to identify web elements on a web page.

• Locators are used to find and interact with elements on a web page.

• Common locators include ID, name, class name, tag name, link text, and partial link text.

• XPath and CSS selectors are also commonly used locators in Selenium.

In Selenium, the Select class is used to work with dropdown elements on a web page.

• The Select class is part of the org.openqa.selenium.support.ui package

• It provides methods to interact with dropdown elements such as selecting options by visible text, value, or index

• To use the Select class, you first need to locate the dropdown element using a locator like ID, name, or class name

Waits in Selenium are used to synchronize the test execution with the application's behavior.

• Waits help in handling synchronization issues between test scripts and web elements

• Types of waits in Selenium include Implicit Wait, Explicit Wait, and Fluent Wait

• Example: WebDriverWait wait = new WebDriverWait(driver, 10); wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("elementID")));

Explicit, implicit, and fluent waits are different types of waits used in automation testing to handle synchronization issues.

• Explicit wait is used to wait for a certain condition to be met before proceeding with the test execution. It is defined by the tester in the code.

• Implicit wait is used to wait for a certain amount of time before throwing an exception if the element is not found. It is defined globally for the e...read more
