How to overlook a particular test method from execution in TestNG?
To overlook a particular test method from execution in TestNG enabled helper attribute is used. This attribute has to be set to false to overlook a test method from execution.ExampleJava class file.@Test(enabled=false) public void verifyRepay(){ System.out.println("Repayment successful"); } @Test public void Login(){ System.out.println("Login is successful "); } @Test public verifyHistory(){ System.out.println ("History verification is successful"); }Here the verifyRepay() method shall be overlooked during execution.
Read MoreHow does the execution of a particular test method depend on other testnmethods in TestNG?
The execution of a particular test method can be made dependent on another test method with the help of dependsOnMethods helper attribute.Example@Test(dependsOnMethods={"Payment"}) public void verifyLoan(){ System.out.println("Loan payment successful"); } @Test public void Payment(){ System.out.println("Payment successful "); } @Test public verifyTransaction(){ System.out.println ("Transaction verification"); }Here in the Java class file, verifyLoan() method will only be executed after the Payment() method is run successfully. But verifyTransaction() method runs independently without having a precondition test method to be executed.
Read MoreWhat is the purpose of the testng.xml file?
The testng.xml file has the numerous uses as listed below −Test cases are executed in groups.Test methods can be included or excluded in the execution.The execution of multiple test cases from multiple java class files can be triggered.Comprises names of the folder, class, method.Capable of triggering parallel execution.Test methods belonging to groups can be included or excluded in the execution.ExampleTestNG.xml file Here as per the xml file, ...
Read MoreWhat are the differences between get() and navigate() method?
The differences between get() and navigate() methods are listed below.sl.no.get()navigate()1It is responsible for loading the page and waits until the page has finished loading.It is only responsible for redirecting the page and then returning immediately.2It cannot track the history of the browser.It tracks the browser history and can perform back and forth in the browser.ExampleWith get().import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import java.util.List; public class LaunchBrw { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver = new ChromeDriver(); String url = "https://www.tutorialspoint.com/index.htm"; ...
Read MoreWhat are the differences between findElement() and findElements() methods?
findElement() and findElements() method tries to search an element in DOM.The differences between them are listed below −sl.no.findElement()findElements()1It returns the first web element which matches with the locator.It returns all the web elements which match with the locator.2Syntax − WebElement button = webdriver.findElement(By.name(""));Syntax − List buttons = webdriver.findElements(By.name(""));3NoSuchElementException is thrown if there are no matching web elementsEmpty list is returned if there are no matching elements.ExampleUsing findElements ().import org.openqa.selenium.By; import org.openqa.selenium.Keys; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; public class RowFindElements { public static void main(String[] args) { System.setProperty("webdriver.chrome.driver", "C:\Users\ghs6kor\Desktop\Java\chromedriver.exe"); WebDriver driver ...
Read MoreWhat is the difference between BLOB and CLOB datatypes?
Blob and Clob together are known as LOB(Large Object Type). The following are the major differences between Blob and Clob data types.BlobClobThe full form of Blob is a Binary Large Object.The full form of Clob is Character Large Object.This is used to store large binary data.This is used to store large textual data.This stores values in the form of binary streams.This stores values in the form of character streams.Using this you can stores files like videos, images, gifs, and audio files.Using this you can store files like text files, PDF documents, word documents etc.MySQL supports this with the following datatypes:TINYBLOBBLOBMEDIUMBLOBLONGBLOBMySQL ...
Read MoreCount divisors of n that have at-least one digit common with n in Java
We are given with a number let’s say, num and the task is to calculate the divisor of a given number thereby count the divisors of num that have at least one digit common with n.Input − num = 24Output − Count is 4Explanation − we will perform the following steps −Firstly, calculate the divisors of a given numberDivisors of 24 are − 1, 2, 3, 4, 6, 8, 12, 24Secondly, check which divisor have at least one digit that matches with the digits of a number2, 4, 12, 24 are the divisors that contain the digit that matches with ...
Read MoreHow to print pid, info, children, and destroy processes in JShell in Java 9?
JShell is a Java Shell tool used to execute simple java statements like classes, methods, interfaces, enums, and etc.. evaluates it, and prints the result in a command-line prompt.Java has improved Process API to manage and control operating system processes. ProcessHandle interface identifies and provides control of native processes, methods to check processes liveness, and destroy the process. ProcessHandle.Info interface gives an Information snapshot of a process.In the below code snippet, we can print pid, info, children, and destroy processes of Process API.in JShell tool.Snippetjshell> ProcessHandle currentProcess = ProcessHandle.current(); currentProcess ==> 3960 jshell> System.out.println("Current Process Id: = " + currentProcess.pid()); Current Process Id: = 3960 jshell> ...
Read MoreHow to get system properties in JShell in Java 9?
JShell is a REPL (Read-Evaluate-Print-Loop) tool used to execute simple statements, evaluates it, and displays the result without a main() method. We can start it by simply type "jshell" in command-line prompt.We need to get the system properties by using System.getProperty() and System.getProperties() methods.In the below code snippet, we can able to display the system properties in the JShell tool by using static method property() of System class.Snippet-1jshell> System.getProperty("java.class.path") $1 ==> "C:\Program Files\Java\jdk-9.0.4\lib;C:\json-jars\json.jar;.;C:\json-jars\json-simple.jar;.;C:\json-jars\gson.jar;.;C:\json-jars\commons-io.jar;.;C:\json-jars\jackson-core.jar;.;C:\json-jars\jackson-databind.jar;.;C:\json-jars\jackson-annotations.jar;.;C:\json jars\flexjson.jar;.;C:\json-jars\jackson-dataformat-xml.jar;.;C:\json-jars\stax2-api.jar;.;C:\json-jars\jackson-dataformat-csv.jar;.;C:\json-jars\javax.json.jar;.;C:\json jars\javax.json-api.jar;.;C:\json-jars\jackson-module-jsonSchema.jar;.;C:\json-jars\json-lib.jar;.;C:\json-jars\commons-lang.jar;.;C:\json-jars\commons-logging.jar;.;"In the below code snippet, we have to use the “properties” object that extends Hashtable. So all properties can be listed as key/value pairs in the JShell tool by using ...
Read MoreHow to implement JShell using JavaFX in Java 9?
JShell is an interactive tool used to implement sample expressions. We can implement JShell programmatically using JavaFX application then we need to import a few packages in the java program listed belowimport jdk.jshell.JShell; import jdk.jshell.SnippetEvent; import jdk.jshell.VarSnippet;In the below example, implemented a sample Java FX application. We will enter different values in the text field and press the "eval" button. It will display values with corresponding data types in a list.Exampleimport javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.*; import javafx.scene.layout.*; import javafx.stage.Stage; import java.util.List; import jdk.jshell.JShell; import jdk.jshell.SnippetEvent; import jdk.jshell.VarSnippet; public class JShellFXTest extends Application { @Override public void start(Stage primaryStage) ...
