We can check if an image is displayed on page with Selenium. To verify an image we shall take the help of Javascript Executor. We shall utilize executeScript method to execute the Javascript commands in Selenium.Then pass the command return arguments[0].complete && typeof arguments[0].naturalWidth != \"undefined\" && arguments[0].naturalWidth > 0 as a parameter to that method. Moreover, the statement import org.openqa.selenium.JavascriptExecutor has to be added in code.SyntaxWebElement i = driver.findElement(By.xpath("//img[@title='Tutorialspoint']")); Boolean p = (Boolean) ((JavascriptExecutor)driver) .executeScript("return arguments[0].complete " + "&& typeof arguments[0].naturalWidth != \"undefined\" " + "&& arguments[0].naturalWidth > 0", i);Let us check if the below image is present on page −ExampleCode ...

We can get the innerHTML of the whole page in Selenium. We shall use the method getPageSource and print the values captured by it in the console.SyntaxString s = driver.getPageSource();We can also get the HTML source code via Javascript commands in Selenium. We shall utilize executeScript method and pass the command return document.body.innerHTML as a parameter to the method.SyntaxJavascriptExecutor j = (JavascriptExecutor) driver; String s = (String) j.executeScript("return document.body.innerHTML;");ExampleCode Implementation with getPageSource.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 PageHTMLcode{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = ...

We can get console.log output from Firefox with Selenium. This is done with the setProperty method.FirefoxDriver.SystemProperty.BROWSER_LOGFILE and the path of the file in which the logs are to be captured are passed as parameters to that method.SyntaxSystem.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE, "FFLogs.txt");After refreshing the project folder, we shall get the FFLogs.txt file where the logs shall be captured.ExampleCode Implementation.import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import java.util.concurrent.TimeUnit; import org.openqa.selenium.logging.LogType; public class FirefoxLogs{ public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe"); // set the System Property to BROWSER_LOGFILE and path of log file System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE, ...

The behind scenes workings of Selenium is illustrated below −Source − https://www.tutorialspoint.com/what-is-web-driver-in-seleniumSelenium webdriver architecture comprises of −Selenium Binding Languages – It can used on multiple languages (Java, Ruby, Javascript, C#, Python, and so on). So it possesses the language bindings for multiple languages.JSON Wire Protocol – It is known as the Javascript Object Notation. It sends the data from the server to the client page. It is built on the concepts of Rest API which conveys information within HTTP servers.Browser Driver – A browser has a browser driver. It communicates with its browser. When a driver gets a command, it ... Read More
We can test pages that need authentication with Selenium. For this, we have to send the credentials of the user to the URL. Actually, we are passing both the username and password appended to the URL.Syntaxhttps://username:password@URL https://admin:admin@the-internet.herokuapp.com/basic_authHere, the admin is the username and password.URL – www.the-internet.herokuapp.com/basic_authLet us see how to accept the authentication pop-up.ExampleCode Implementation.import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; public class TestAuthnPopup{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String t = "admin"; // adding username, password with ...

Kivy is an pen source Python library for rapid development of applications that make use of innovative user interfaces, such as multi-touch apps. It is used to develop the Android application, as well as Desktops applications. In this article we will see how to add labels to the windows created through Kivy.Creating LabelIn the below example we create a window and give it a custom label by using Label function available in uix.lable module. Once we run the app with this code we get the new window showing the custom label.Examplefrom kivy.app import App from kivy.uix.label import Label class ... Read More
We can click and wait in Selenium. This can be achieved by the synchronization concept. We shall use the explicit wait condition and wait for an element to be clickable prior to the next step.The explicit wait waits for a specified amount of time before throwing an exception. To verify if an element is clickable, we can use the expected condition elementToBeClickable.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; import org.openqa.selenium.support.ui.ExpectedConditions; import org.openqa.selenium.support.ui.WebDriverWait; public class ElementClickableWait{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); ...

In data analysis using python we may come across situation when two lists need to be merged. But it may be a challenge to handle the duplicate elements present in those lists. In this article we will see how to combine two lists by maintain all the elements form the first list and only the unique elements from the second list.Using extendIn this approach we take the first list and create a result list. Then we design a for loop to check for the presence of element of the first list in the second list and if the element is ... Read More
We can connect to Chromium headless with Selenium. The headless execution helps in reducing resource utilization and is a modern technique used in the industry.Chrome can be used in headless mode after the 59 version. The ChromeOptions class is used to change the default browser behavior. The headless value is passed to the addArguments method as a parameter for headless execution.SyntaxChromeOptions op = new ChromeOptions(); op.addArguments("headless"); WebDriver d = new ChromeDriver(op);ExampleCode Implementation.import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; import org.openqa.selenium.chrome.ChromeOptions; import java.util.concurrent.TimeUnit; public class HeadlessChromium{ public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); //ChromeOptions object ...

A list in python is normally a 1D list where the elements are listed one after another. But in a 2D list we have list nested inside the outer list. In this article we will see how to create a 2D list from a given 1D list. We also supply the values for the number of elements inside the 2D list to the program.Using append and indexIn this approach we will create a for loop to loop through each element in the 2D list and use it as an index for the new list to be created. We keep incrementing ... Read More
