Read MoreHow to simulate pressing enter in html text input with Selenium?
We can simulate pressing enter in the html text input box with Selenium webdriver. We shall take the help of sendKeys method and pass Keys.ENTER as an argument to the method. Besides, we can pass Keys.RETURN as an argument to the method to perform the same task.Also, we have to import org.openqa.selenium.Keys package to the code for using the Keys class. Let us press ENTER/RETURN after entering some text inside the below input box.ExampleCode Implementation with Keys.ENTER.import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.By; import org.openqa.selenium.Keys; public class PressEnter{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", ...
Read MoreHow do I change focus to a new popup tab in Selenium?
We can change focus to a new popup tab with Selenium webdriver. The getWindowHandles and getWindowHandle methods are available to handle new popup tabs. The getWindowHandles method stores all the currently opened window handles in Set data structure.The getWindowHandle method stores the window handle of the opened browser in focus. The iterator method is used to iterate over all the window handle ids. We have to add import java.util.Set to accommodate Set and import java.util.List and import java.util.Iterator statements to accommodate the iterator in our code.Selenium driver object can access the elements of the parent window. In order to switch ...
Read MoreHow to wait until an element no longer exists in Selenium?
We can wait until an element no longer exists in Selenium webdriver. This can be achieved with synchronization in Selenium. We shall add an explicit wait criteria where we shall stop or wait till the element no longer exists.Timeout exception is thrown once the explicit wait time has elapsed and the expected behavior of the element is still not available on the page. To check if an element no longer exists on the page, we can take the help of the expected condition invisibilityOfElementLocated.To implement explicit wait conditions, we have to take help of the WebDriverWait and ExpectedCondition class.ExampleCode Implementation.import ...
Read MoreSelenium Web Test Automation Framework Best Practices.
The best practices for Selenium web test automation framework are listed below −Use of dynamic waits like implicit wait and explicit wait instead of using Thread.sleep in the framework to handle sync issues in the application.Usage of Page Object Model framework design to segregate the test scripts from the locators. In case of changes in the webelement properties, test scripts need not be modified only the locators undergo change.Usage of Behavior Driven Development framework. This allows the participation of all members in the agile team to participate in product development.Encourage testing to start from very early phases and in regular ...
Read MoreHow do you click on an element which is hidden using Selenium WebDriver?
We can click on an element which is hidden with Selenium webdriver. The hidden elements are the ones which are present in the DOM but not visible on the page. Mostly the hidden elements are defined by the CSS property style="display:none;". In case an element is a part of the form tag, it can be hidden by setting the attribute type to the value hidden.Selenium by default cannot handle hidden elements and throws ElementNotVisibleException while working with them. Javascript Executor is used to handle hidden elements on the page. Selenium runs the Javascript commands with the executeScript method. The commands ...
Read MoreHow to navigate back to current page from Frame in selenium webdriver?
We can navigate back to the current page from frame with Selenium webdriver. A frame is defined with , or tag in html code. A frame is used to embed an HTML document within another HTML document.Selenium by default has access to the main browser driver. In order to access a frame element, the driver focus has to shift from the main browser window to the frame. To again focus back to the current page from frame, the method switchTo().defaultContent() is used.ExampleCode Implementation.import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class SwitchBackFrame{ public static ...
Read MoreHow to use regex in selenium locators?
We can use regex in locators in Selenium webdriver. This can be achieved while we identify elements with the help of xpath or css locator. Let us have a look at the class of an element in its html code. The class attribute value is gsc-input.Here, with the css expression, we can use the * and perform a partial match with the class attribute value. The css value shall be input[class*='input']. This means the subtext input is present in the actual text gsc-input. We can also use the ^ and perform a match with the class. The css value shall ...
