To reduce execution time in Selenium, optimize test scripts, use efficient locators, and run tests in parallel.

• Optimize test scripts by removing unnecessary steps and reducing wait times

• Use efficient locators such as CSS selectors instead of XPath

• Run tests in parallel using tools like Selenium Grid or TestNG

• Use headless browsers like PhantomJS to speed up tests

• Use page object model to reduce code duplication and improve maintainability

An interface is a contract between two entities that defines the communication between them.

• An interface defines a set of methods that a class must implement.

• It provides a way to achieve abstraction and loose coupling.

• Interfaces can be used to achieve multiple inheritance in Java.

• Example: Java's Comparable interface defines a method to compare objects.

• Example: Selenium WebDriver interface defines methods to interact with web elements.

Explicit wait is a mechanism in Selenium that allows the automation tester to wait for a certain condition to occur before proceeding further.

• Syntax: WebDriverWait wait = new WebDriverWait(driver, timeoutInSeconds);

• wait.until(ExpectedConditions.condition);

• Example: WebDriverWait wait = new WebDriverWait(driver, 10);

• wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("elementId")));
