What is the major difference between “assert” and “verify” cmd's in Selenium?

Both “assert” and “verify” commands check whether the given condition is true or false :

  • Assert: It stops the execution of the testing if the given condition is false else continue with the further tests.

 Example: assertEquals (expectedMessage, actualMessage);

  • Verify: It doesn’t stop the flow of execution irrespective of the condition being true or false. 

What is the difference between driver.close() and driver.quit() command in Selenium?

  • driver.close() It closes the currently active window on which the user is working.

How can we create right-click and mouse hover actions in Selenium?

This code can replicate right-click action:

 Actions action = new Actions(driver);

 WebElement element = driver.findElement ( By.id("elementId"));

 action.moveToElement( element).perform();

Locating Hyperlinks by Link Text:

driver.FindElement(By.LinkText ("edit this page")).Click();

Locating by ClassName:

driver.findElement( By.className("Header"));

Locating by TagName:

driver.findElement( By.tagName("select') ).click();

  1. driver.navigate().refresh(); - This method refreshes the current page.

  2. driver.navigate().to( "https://neptuneworld.in/"); - Navigates to the provided URL.

  3. driver.navigate().forward(); - This method does the same operation as clicking on the Forward Button of any browser. It neither accepts nor returns anything.
